User design methods were applied to sonify data that could allow the classification of accretion discs. The sonification was developed over three stages: a requirements gathering exercise that inquired about the astronomer’s work and the data, design and development, as well as an evaluation. Twenty datasets were sonified and analysed. The sonification effectively represented the accretion discs allowing the astronomer to commence a preliminary, comparative classification. Multiple parameter mappings provide rich auditory stimuli. Spatial mapping and movement allow for easier identification of fast changes and peaks in the data which improved the understanding of the extent of these changes.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/69712433" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="aa7a39afc15db856e8bb966d81ae38b4" rel="nofollow" data-download="{"attachment_id":79703105,"asset_id":69712433,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/79703105/download_file?st=MTczOTgwMDAyMCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="14393530" href="https://napier.academia.edu/MichaelQuinton">Michael Quinton Ph.D</a><script data-card-contents-for-user="14393530" type="text/json">{"id":14393530,"first_name":"Michael","last_name":"Quinton Ph.D","domain_name":"napier","page_name":"MichaelQuinton","display_name":"Michael Quinton Ph.D","profile_url":"https://napier.academia.edu/MichaelQuinton?f_ri=11056","photo":"https://0.academia-photos.com/14393530/3934071/48137011/s65_michael.quinton.jpg"}</script></span></span></li><li class="js-paper-rank-work_69712433 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="69712433"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 69712433, container: ".js-paper-rank-work_69712433", });

WASP-135b is a hot Jupiter with a radius of 1.30±0.09 R Jup , a mass of 1.90±0.08 M Jup and an orbital period of 1.401 days. Its host is a Sun-like star, with a G5 spectral type and a mass and radius of 0.98±0.06 M ⊙ and 0.96±0.05 R ⊙ respectively. The proximity of the planet to its host means that WASP-135b receives high levels of insolation, which may be the cause of its inflated radius. Additionally, we find weak evidence of a transfer of angular momentum from the planet to its star.","downloadable_attachments":[{"id":86049922,"asset_id":79282014,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":219280754,"first_name":"Alexios","last_name":"Liakos","domain_name":"independent","page_name":"AlexiosLiakos","display_name":"Alexios Liakos","profile_url":"https://independent.academia.edu/AlexiosLiakos?f_ri=11056","photo":"https://0.academia-photos.com/219280754/77360586/65896704/s65_alexios.liakos.png"}],"research_interests":[{"id":498,"name":"Physics","url":"https://www.academia.edu/Documents/in/Physics?f_ri=11056","nofollow":true},{"id":11056,"name":"Exoplanets","url":"https://www.academia.edu/Documents/in/Exoplanets?f_ri=11056","nofollow":true},{"id":39286,"name":"Exoplanet detection","url":"https://www.academia.edu/Documents/in/Exoplanet_detection?f_ri=11056","nofollow":true},{"id":41236,"name":"Extrasolar planets","url":"https://www.academia.edu/Documents/in/Extrasolar_planets?f_ri=11056","nofollow":true},{"id":469820,"name":"QC","url":"https://www.academia.edu/Documents/in/QC?f_ri=11056"},{"id":1561236,"name":"Hot Jupiters","url":"https://www.academia.edu/Documents/in/Hot_Jupiters?f_ri=11056"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_71963943" data-work_id="71963943" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/71963943/Ultraviolet_radiation_constraints_around_the_circumstellar_habitable_zones">Ultraviolet radiation constraints around the circumstellar habitable zones</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Ultraviolet radiation is known to inhibit photosynthesis, induce DNA destruction and cause damage to a wide variety of proteins and lipids.

The field of exoplanet research is moving towards the detection and characterization of habitable planets. These exo-Earths can be easily found around low-mass stars by using either photometric transit or radial-velocity (RV) techniques. In the latter case the gain is twofold because the signal induced by the planet of a given mass is higher due to the more favourable planet-star mass ratio and because the habitable zone lies closer to the star. However, late-type stars emit mainly in the infrared (IR) wavelength range, which calls for IR instruments. Aims. SPIRou is a stable RV IR spectrograph addressing these ambitious scientific objectives. As with any other spectrograph, calibration and drift monitoring is fundamental to achieve high precision. However, the IR domain suffers from a lack of suitable reference spectral sources. Our goal was to build, test and finally operate a Fabry-Pérot-based RV-reference module able to provide the needed spectral information over the full wavelength range of SPIRou. Methods. We adapted the existing HARPS Fabry-Pérot calibrator for operation in the IR domain. After manufacturing and assembly, we characterized the FP RV-module in the laboratory before delivering it to the SPIRou integration site. In particular, we measured finesse, transmittance, and spectral flux of the system. Results. The measured finesse value of F = 12.8 corresponds perfectly to the theoretical value. The total transmittance at peak is of the order of 0.5%, mainly limited by fibre-connectors and interfaces. Nevertheless, the provided flux is in line with the the requirements set by the SPIRou instrument. Although we could test the stability of the system, we estimated it by comparing the SPIRou Fabry-Pérot with the already operating HARPS system and demonstrated a stability of better than 1 m s −1 during a night. Conclusions. Once installed on SPIRou, we will test the full spectral characteristics and stability of the RV-reference module. The goal will be to prove that the line position and shape stability of all lines is better than 0.3 m s −1 between two calibration sequences (typically 24 hours), such that the RV-reference module can be used to monitor instrumental drifts. In principle, the system is also intrinsically stable over longer time scales such that it can also be used for calibration purposes.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/31493616" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="5bfb8cff9bf41edc0d9e9ed814d3c869" rel="nofollow" data-download="{"attachment_id":51843131,"asset_id":31493616,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/51843131/download_file?st=MTczOTgwMDAyMCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="1271094" href="https://unige.academia.edu/FedericaCersullo">Federica Cersullo</a><script data-card-contents-for-user="1271094" type="text/json">{"id":1271094,"first_name":"Federica","last_name":"Cersullo","domain_name":"unige","page_name":"FedericaCersullo","display_name":"Federica Cersullo","profile_url":"https://unige.academia.edu/FedericaCersullo?f_ri=11056","photo":"https://0.academia-photos.com/1271094/466934/588952/s65_federica.cersullo.jpg"}</script></span></span></li><li class="js-paper-rank-work_31493616 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="31493616"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 31493616, container: ".js-paper-rank-work_31493616", });

With the discovery of these planets, called “exoplanets,” comes the question of extraterrestrial life, a concept scientists have been exploring for years. The possibility of exoplanetary habitability relies on a number of factors, such as spectral type, density, and eccentricity, but most importantly: whether the exoplanet in question contains water, the fundamental requirement for life, as we know it, to exist. To determine whether an exoplanet provides the ideal conditions for sustaining this vital ingredient for life, we considered the concept of the Goldilocks Zone, or the circumstellar habitable zone (CHZ)—the range of orbits around a star where liquid water is capable of existing. The research we have been conducting this summer utilizes the public dataset provided by NASA and Caltech and data mining methods, including Python and Microsoft Excel, to identify exoplanets with potentially habitable conditions. The discovery of the exoplanet K2-18b’s water vapor-containing atmosphere was a major part of our research, in which we focused on identifying exoplanets with similar attributes to that of K2-18b, in hopes that they too may be able to retain atmospheric water vapor. After a two-month period, we discovered that 59 exoplanets orbit in the CHZ of their host star. As for the K2-18b ruleset, only 1 planet, K2-3d, satisfies the conditions. We believe K2-3d to have a high degree of similarity to K2-18b, but more in-depth analysis will have to be conducted to conclude its potential to support atmospheric water vapor and life as we know it.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/44808806" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="b3d0b047417f6b5b760865a0f7adc26b" rel="nofollow" data-download="{"attachment_id":65308366,"asset_id":44808806,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/65308366/download_file?st=MTczOTgwMDAyMCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="174030512" href="https://independent.academia.edu/HrithikPai">Hrithik Pai</a><script data-card-contents-for-user="174030512" type="text/json">{"id":174030512,"first_name":"Hrithik","last_name":"Pai","domain_name":"independent","page_name":"HrithikPai","display_name":"Hrithik Pai","profile_url":"https://independent.academia.edu/HrithikPai?f_ri=11056","photo":"https://0.academia-photos.com/174030512/48523259/38495965/s65_hrithik.pai.jpg"}</script></span></span></li><li class="js-paper-rank-work_44808806 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="44808806"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 44808806, container: ".js-paper-rank-work_44808806", });

We believe K2-3d to have a high degree of similarity to K2-18b, but more in-depth analysis will have to be conducted to conclude its potential to support atmospheric water vapor and life as we know it.","downloadable_attachments":[{"id":65308366,"asset_id":44808806,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":174030512,"first_name":"Hrithik","last_name":"Pai","domain_name":"independent","page_name":"HrithikPai","display_name":"Hrithik Pai","profile_url":"https://independent.academia.edu/HrithikPai?f_ri=11056","photo":"https://0.academia-photos.com/174030512/48523259/38495965/s65_hrithik.pai.jpg"}],"research_interests":[{"id":2008,"name":"Machine Learning","url":"https://www.academia.edu/Documents/in/Machine_Learning?f_ri=11056","nofollow":true},{"id":2009,"name":"Data Mining","url":"https://www.academia.edu/Documents/in/Data_Mining?f_ri=11056","nofollow":true},{"id":11056,"name":"Exoplanets","url":"https://www.academia.edu/Documents/in/Exoplanets?f_ri=11056","nofollow":true},{"id":47599,"name":"Astronomy","url":"https://www.academia.edu/Documents/in/Astronomy?f_ri=11056","nofollow":true},{"id":334552,"name":"Habitable Exoplanets","url":"https://www.academia.edu/Documents/in/Habitable_Exoplanets?f_ri=11056"},{"id":1336364,"name":"Habitable Zones","url":"https://www.academia.edu/Documents/in/Habitable_Zones?f_ri=11056"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_25947453" data-work_id="25947453" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/25947453/Brief_History_of_Exoplanetology">Brief History of Exoplanetology</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest">Brief History of Exoplanetology</div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/25947453" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="3845d27f06f4534a91b6dd8ef686ce9d" rel="nofollow" data-download="{"attachment_id":46302542,"asset_id":25947453,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/46302542/download_file?st=MTczOTgwMDAyMCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="32732614" href="https://independent.academia.edu/LlerenaAlberto">Alberto Llerena</a><script data-card-contents-for-user="32732614" type="text/json">{"id":32732614,"first_name":"Alberto","last_name":"Llerena","domain_name":"independent","page_name":"LlerenaAlberto","display_name":"Alberto Llerena","profile_url":"https://independent.academia.edu/LlerenaAlberto?f_ri=11056","photo":"https://0.academia-photos.com/32732614/9820917/10944088/s65_alberto.llerena.jpg_oh_847cd30947c3eaf073156ba18fca7cf4_oe_5657a031___gda___1448521500_c1c5b86ac1c3d724f3398fef93bad8ee"}</script></span></span></li><li class="js-paper-rank-work_25947453 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="25947453"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 25947453, container: ".js-paper-rank-work_25947453", });

Advanced civilizations may exist on these, and significant effort has been expended on the theoretical analysis of planetary systems, and accompanying practical detection instruments.<br /><br />The longevity of technological civilizations is unknown, as is the probability of less advanced societies becoming technological. Accordingly, searching for pre-industrial extra-terrestrial societies may be more productive.<br /><br />Using the earth as a model, a consideration of possible detectible proxies suggests that observation of seasonal agriculture may be possible in the near future – particularly in ideal circumstances, for which quantitative analysis is provided. More speculatively, other detectible processes may include: species introduction; climate change; large urban fires and land-use or aquatic changes.<br /><br />Primitive societies may be both aware that their activities may be observed from other planets, and may deliberately adjust these activities to aid or conceal detection.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/44703950" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="17c2422bbbf0abeaf047f90072899bb4" rel="nofollow" data-download="{"attachment_id":65181797,"asset_id":44703950,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/65181797/download_file?st=MTczOTgwMDAyMCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="16446192" href="https://ucl.academia.edu/AndrewLockley">Andrew Lockley</a><script data-card-contents-for-user="16446192" type="text/json">{"id":16446192,"first_name":"Andrew","last_name":"Lockley","domain_name":"ucl","page_name":"AndrewLockley","display_name":"Andrew Lockley","profile_url":"https://ucl.academia.edu/AndrewLockley?f_ri=11056","photo":"https://0.academia-photos.com/16446192/4478962/35481100/s65_andrew.lockley.jpg"}</script></span></span></li><li class="js-paper-rank-work_44703950 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="44703950"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 44703950, container: ".js-paper-rank-work_44703950", });

Advanced civilizations may exist on these, and significant effort has been expended on the theoretical analysis of planetary systems, and accompanying practical detection instruments.\n\nThe longevity of technological civilizations is unknown, as is the probability of less advanced societies becoming technological. Accordingly, searching for pre-industrial extra-terrestrial societies may be more productive.\n\nUsing the earth as a model, a consideration of possible detectible proxies suggests that observation of seasonal agriculture may be possible in the near future – particularly in ideal circumstances, for which quantitative analysis is provided. More speculatively, other detectible processes may include: species introduction; climate change; large urban fires and land-use or aquatic changes.\n\nPrimitive societies may be both aware that their activities may be observed from other planets, and may deliberately adjust these activities to aid or conceal detection.","downloadable_attachments":[{"id":65181797,"asset_id":44703950,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":16446192,"first_name":"Andrew","last_name":"Lockley","domain_name":"ucl","page_name":"AndrewLockley","display_name":"Andrew Lockley","profile_url":"https://ucl.academia.edu/AndrewLockley?f_ri=11056","photo":"https://0.academia-photos.com/16446192/4478962/35481100/s65_andrew.lockley.jpg"}],"research_interests":[{"id":5001,"name":"Astrobiology","url":"https://www.academia.edu/Documents/in/Astrobiology?f_ri=11056","nofollow":true},{"id":11056,"name":"Exoplanets","url":"https://www.academia.edu/Documents/in/Exoplanets?f_ri=11056","nofollow":true},{"id":334552,"name":"Habitable Exoplanets","url":"https://www.academia.edu/Documents/in/Habitable_Exoplanets?f_ri=11056","nofollow":true}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_49090548 coauthored" data-work_id="49090548" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/49090548/The_Exploration_of_Habitable_Exoplanets_using_Data_Mining_Algorithms_and_Data_Manipulation">The Exploration of Habitable Exoplanets using Data Mining Algorithms and Data Manipulation</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">The NASA Exoplanet Archive is a dataset that is an extraction from the total sets of data from the Keck, Kepler, TESS, and Gaia observations, where observations show that the observed stellar objects have been determined to possess one or... <a class="more_link u-tcGrayDark u-linkUnstyled" data-container=".work_49090548" data-show=".complete" data-hide=".summarized" data-more-link-behavior="true" href="#">more</a></div><div class="complete hidden">The NASA Exoplanet Archive is a dataset that is an extraction from the total sets of data from the Keck, Kepler, TESS, and Gaia observations, where observations show that the observed stellar objects have been determined to possess one or more planets.

JWST will revolutionize our knowledge of the physical properties of dozens to possibly hundreds of exoplanets by making a variety of different types of observations. Here we focus on transits and phase curves; direct detection via coronagraphy was considered in a 2007 white paper (for all JWST white papers see papers) and will be revisited in the near future. JWST 's unique combination of high sensitivity and broad wavelength coverage enables the accurate measurement of transit and orbital parameters with high signal-to-noise (SNR). Most importantly, JWST will investigate planetary atmospheres, determine atomic and molecular compositions, probe vertical and horizontal structure, and follow dynamical evolution (i.e. exoplanet weather). It will do this for a diverse population of planets of varying masses and densities, in a wide variety of environments characterized by a range of host star masses and metallicities, orbital semi-major axes and eccentricities. 3 The sensitivity of JWST over its wavelength range of 0.6 to 28 microns compared to other missions and ground-based facilities has been amply documented () and JWST 's halo orbit around the Earth-Sun L2 point provides long, highly stable, uninterrupted observing sequences 3 Of particular interest for JWST will be small planets (R< 2-4R ⊕ ) located at a distance from their host stars such that their equilibrium temperatures could be comparable to that of our Earth. The range of the so-called "Habitable Zone" has been argued over by many authors since its original definition .

JWST will revolutionize our knowledge of the physical properties of dozens to possibly hundreds of exoplanets by making a variety of different types of observations. Here we focus on transits and phase curves; direct detection via coronagraphy was considered in a 2007 white paper (for all JWST white papers see papers) and will be revisited in the near future. JWST 's unique combination of high sensitivity and broad wavelength coverage enables the accurate measurement of transit and orbital parameters with high signal-to-noise (SNR). Most importantly, JWST will investigate planetary atmospheres, determine atomic and molecular compositions, probe vertical and horizontal structure, and follow dynamical evolution (i.e. exoplanet weather). It will do this for a diverse population of planets of varying masses and densities, in a wide variety of environments characterized by a range of host star masses and metallicities, orbital semi-major axes and eccentricities. 3 The sensitivity of JWST over its wavelength range of 0.6 to 28 microns compared to other missions and ground-based facilities has been amply documented () and JWST 's halo orbit around the Earth-Sun L2 point provides long, highly stable, uninterrupted observing sequences 3 Of particular interest for JWST will be small planets (R\u003c 2-4R ⊕ ) located at a distance from their host stars such that their equilibrium temperatures could be comparable to that of our Earth. The range of the so-called \"Habitable Zone\" has been argued over by many authors since its original definition .

Whilst much effort has been spent on searching for Earth-like planets, large moons may also be common, temperate abodes for life as well. The methods to detect extrasolar moons, or "exomoons" are more subtle than their planetary counterparts and in this thesis I aim to provide a method to find such bodies in transiting systems, which offer the greatest potential for detection. Before one can search for the tiny perturbations to the planetary signal, an understanding of the planetary transit must be established. Therefore, in Chapters 3 to 5 I discuss the transit model and provide several new insights. Chapter 4 presents new analytic expressions for the times of transit minima and the transit duration, which will be critical in the later search for exomoons. Chapter 5 discusses two sources of distortion to the transit signal, namely blending (with a focus on the previously unconsidered self-blending scenario) and light curve smearing due to long integration times. I provide methods to compensate for both of these effects, thus permitting for the accurate modelling of the planetary transit light curve. In Chapter 6, I discuss methods to detect exomoons through their gravitational influence on the host planet, giving rise to transit timing and duration variations (TTV and TDV). The previously known TTV effect is updated with a new model and the associated critical problems are outlined. I then predict a new effect, TDV, which solves these problems, making exomoon detection viable. Chapter 7 presents a feasibility study for detecting habitable-zone exomoons with Kepler, where it is found that moons down to 0.2 Earth masses are detectable.

The habitability of this type of objects are becoming increasingly interesting and popular. In this paper, I present the discussion about basic properties of moons including formation and habitability in our solar system and beyond and ﬁndthat the satellites around gas giants are mainly formed via accretion mechanism. Next, the discussion of current techniques of detecting exomoons such as direct imaging, gravitational microlensing and transit time variation(TTV)and transit duration variation(TDV) is demonstrated. It is possible to directly image exomoons with active tidal heating activities, and the result of a planet-moon system using microlensing and the detailed explanation of TTV and TDV are shown. Then, some hypothetical simulations within which constraints such as magnetic ﬁeld shielding, runaway greenhouse eﬀect and orbital dynamics are applied. Researchers reach the conclusion that exomoons need to be embedded in the host planet’s magnetosphere and generate its own magnetic ﬁeld to protect radiation from both the star and the planet. In the simulation about runaway greenhouse eﬀect, people found that it is possible for an moon to be in habitable even if the planet does not spend its entire time in the habitable zone(HZ). Finally suggestions on future observations and simulations have been made along with a brief introduction of future extra solar objects detection mis-sions. All facts indicate that the study of the exomoons is of great attraction and promising result in the near future.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/6949157" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="dc66b4d8428b08d1fee6ce67f3573f82" rel="nofollow" data-download="{"attachment_id":33618717,"asset_id":6949157,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/33618717/download_file?st=MTczOTgwMDAyMCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="5811633" href="https://illinois.academia.edu/LunanSun">Lunan Sun</a><script data-card-contents-for-user="5811633" type="text/json">{"id":5811633,"first_name":"Lunan","last_name":"Sun","domain_name":"illinois","page_name":"LunanSun","display_name":"Lunan Sun","profile_url":"https://illinois.academia.edu/LunanSun?f_ri=11056","photo":"https://0.academia-photos.com/5811633/3379286/20941749/s65_lunan.sun.jpg"}</script></span></span></li><li class="js-paper-rank-work_6949157 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="6949157"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 6949157, container: ".js-paper-rank-work_6949157", });

The habitability of this type of objects are becoming increasingly interesting and popular. In this paper, I present the discussion about basic properties of moons including formation and habitability in our solar system and beyond and ﬁndthat the satellites around gas giants are mainly formed via accretion mechanism. Next, the discussion of current techniques of detecting exomoons such as direct imaging, gravitational microlensing and transit time variation(TTV)and transit duration variation(TDV) is demonstrated. It is possible to directly image exomoons with active tidal heating activities, and the result of a planet-moon system using microlensing and the detailed explanation of TTV and TDV are shown. Then, some hypothetical simulations within which constraints such as magnetic ﬁeld shielding, runaway greenhouse eﬀect and orbital dynamics are applied. Researchers reach the conclusion that exomoons need to be embedded in the host planet’s magnetosphere and generate its own magnetic ﬁeld to protect radiation from both the star and the planet. In the simulation about runaway greenhouse eﬀect, people found that it is possible for an moon to be in habitable even if the planet does not spend its entire time in the habitable zone(HZ). Finally suggestions on future observations and simulations have been made along with a brief introduction of future extra solar objects detection mis-sions. All facts indicate that the study of the exomoons is of great attraction and promising result in the near future.","downloadable_attachments":[{"id":33618717,"asset_id":6949157,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":5811633,"first_name":"Lunan","last_name":"Sun","domain_name":"illinois","page_name":"LunanSun","display_name":"Lunan Sun","profile_url":"https://illinois.academia.edu/LunanSun?f_ri=11056","photo":"https://0.academia-photos.com/5811633/3379286/20941749/s65_lunan.sun.jpg"}],"research_interests":[{"id":11056,"name":"Exoplanets","url":"https://www.academia.edu/Documents/in/Exoplanets?f_ri=11056","nofollow":true},{"id":213732,"name":"Exomoons","url":"https://www.academia.edu/Documents/in/Exomoons?f_ri=11056","nofollow":true}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_9382094" data-work_id="9382094" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/9382094/Beyond_the_Boundary_The_Greatest_Challenge_Manned_Interstellar_Travel">Beyond the Boundary - The Greatest Challenge: Manned Interstellar Travel</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest">Beyond the Boundary: Exploring the Science and Culture of Interstellar Spaceflight</div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/9382094" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="2b3194fcfd3cd104813f3cb298858a1b" rel="nofollow" data-download="{"attachment_id":35709832,"asset_id":9382094,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/35709832/download_file?st=MTczOTgwMDAyMCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="252763" href="https://turn-de.academia.edu/AndreasMHein">Andreas M.

It is a huge, self-contained and self-sustained interstellar vehicle. It travels at a fraction of a per cent of the speed of light and needs several centuries to reach its target star system. The wellknown world ship concept by Alan Bond and Anthony Martin was intended to show its principal feasibility. However, several important issues haven’t been addressed so far: the relationship between crew size and robustness of knowledge transfer, reliability, and alternative mission architectures. This paper addresses these gaps. Furthermore, it gives an update on target star system choice, and develops possible mission architectures. The derived conclusions are: a large population size leads to robust knowledge transfer and cultural adaptation. These processes can be improved by new technologies. World ship reliability depends on the availability of an automatic repair system, as in the case of the Daedalus probe. Star systems with habitable planets are probably farther away than systems with enough resources to construct space colonies. Therefore, missions to habitable planets have longer trip times and have a higher risk of mission failure. On the other hand, the risk of <br />constructing colonies is higher than to establish an initial settlement on a habitable planet. Mission architectures with precursor probes have the potential to significantly reduce trip and colonization risk without being significantly more costly than architectures without. In summary world ships remain an interesting concept, although they require a space colony-based civilization within our own solar system before becoming feasible.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/2111006" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="23e13c2f3bb8c2ab564185e3ae379767" rel="nofollow" data-download="{"attachment_id":30294912,"asset_id":2111006,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/30294912/download_file?st=MTczOTgwMDAyMCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="252763" href="https://turn-de.academia.edu/AndreasMHein">Andreas M.

Presently, over 3800 exoplanets, representing a very wide range of physical and chemical environments, are known. Scientists are not only looking for traces of life outside Earth, but they are also trying to find out which of Earth's known organisms (ex: tardigrades (water bears)) would be able to survive on other planets. In our study, we have established a metric tool for distinguishing the potential survivability of active and cryptobiotic tardigrades on rocky-water and water-gas planets in our solar system and exoplanets, taking into consideration the geometrical means of six physical parameters such as radius, density, escape velocity, revolution period, surface temperature, and surface pressure of the considered planets. More than 3800 exoplanets are available as the main sample from Planetary Habitable Laboratory – Exoplanet Catalog (PHL-EC), from which we have chosen 57 exoplanets in our study including Earth and Mars, with water composition as reference. The Active Tardigrade Index (ATI) and Cryptobiotic Tardigrade Index (CTI) are two metric indices with minimum value 0 (= tardigrades cannot survive) and maximum 1 (= tardigrades will survive in their respective state). Values between 0 and 1 indicate a percentage chance of the active or cryptobiotic tardigrades surviving on a given exoplanet. Among known planets some of the exoplanets are tabulated as ATI and CTI indices for sample representation like: Kepler-100d, Kepler-48d, Kepler-289b, TRAPPIST-1 f and Kepler-106e. The results with Mars as the threshold indicates that Mars could be the only rock-water composition planet that could be more suitable for tardigrades than other considered exoplanets.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/37237423" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="3bfe24eb71711dad5e8e82c6cdbd5aa7" rel="nofollow" data-download="{"attachment_id":57189466,"asset_id":37237423,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/57189466/download_file?st=MTczOTgwMDAyMCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="67117599" href="https://christuniversity.academia.edu/MadhuKashyapJagadeesh">Madhu Kashyap Jagadeesh</a><script data-card-contents-for-user="67117599" type="text/json">{"id":67117599,"first_name":"Madhu Kashyap","last_name":"Jagadeesh","domain_name":"christuniversity","page_name":"MadhuKashyapJagadeesh","display_name":"Madhu Kashyap Jagadeesh","profile_url":"https://christuniversity.academia.edu/MadhuKashyapJagadeesh?f_ri=11056","photo":"https://0.academia-photos.com/67117599/17464444/17544324/s65_madhu_kashyap.jagadeesh.jpg"}</script></span></span></li><li class="js-paper-rank-work_37237423 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="37237423"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 37237423, container: ".js-paper-rank-work_37237423", });

Görme, işitme, koklama, tatma ve dokunma yeteneklerimiz arasında, dilin inşası görevi en yüksek oranda işitme duyumuza düşmektedir. Dil, ortam ve koşulları dinleyerek, işiterek ve taklit ederek kurulmuş son derece teknik bir mekanizmadır ve en temel bir varoluş ihtiyacıdır. Mekik ortamı dışındaki uzay koşulları, yok denecek kadar az olan atom seyrekliği nedeniyle (1cm3 alan içinde 1 atom), kokuyu, sesi, tadı ve dokunma duyusunu taşıyabilecek durumda değildir. Sadece taşıyamamak değil, bu duyularımızın alıcısı olacağı etki birimleri hiç oluşmayacaktır.","downloadable_attachments":[{"id":62652228,"asset_id":42477110,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":5089287,"first_name":"Kamil","last_name":"Kartal","domain_name":"independent","page_name":"KamilKartal","display_name":"Kamil Kartal","profile_url":"https://independent.academia.edu/KamilKartal?f_ri=11056","photo":"https://0.academia-photos.com/5089287/2224180/2603553/s65_kamil.kartal.jpg"}],"research_interests":[{"id":499,"name":"Acoustics","url":"https://www.academia.edu/Documents/in/Acoustics?f_ri=11056","nofollow":true},{"id":700,"name":"Space Sciences","url":"https://www.academia.edu/Documents/in/Space_Sciences?f_ri=11056","nofollow":true},{"id":2417,"name":"Planetary Science","url":"https://www.academia.edu/Documents/in/Planetary_Science?f_ri=11056","nofollow":true},{"id":3146,"name":"Shakespeare","url":"https://www.academia.edu/Documents/in/Shakespeare?f_ri=11056","nofollow":true},{"id":4535,"name":"Space astronomy","url":"https://www.academia.edu/Documents/in/Space_astronomy?f_ri=11056"},{"id":7091,"name":"History of Space Travel","url":"https://www.academia.edu/Documents/in/History_of_Space_Travel?f_ri=11056"},{"id":11056,"name":"Exoplanets","url":"https://www.academia.edu/Documents/in/Exoplanets?f_ri=11056"},{"id":13320,"name":"Mars","url":"https://www.academia.edu/Documents/in/Mars?f_ri=11056"},{"id":33806,"name":"Turkish Language","url":"https://www.academia.edu/Documents/in/Turkish_Language?f_ri=11056"},{"id":36190,"name":"Cultural Astronomy","url":"https://www.academia.edu/Documents/in/Cultural_Astronomy?f_ri=11056"},{"id":46787,"name":"Mustafa Kemal Atatürk","url":"https://www.academia.edu/Documents/in/Mustafa_Kemal_Ataturk?f_ri=11056"},{"id":47599,"name":"Astronomy","url":"https://www.academia.edu/Documents/in/Astronomy?f_ri=11056"},{"id":188203,"name":"Türkçe Eğitimi","url":"https://www.academia.edu/Documents/in/Turkce_Egitimi?f_ri=11056"},{"id":588502,"name":"Tesla","url":"https://www.academia.edu/Documents/in/Tesla?f_ri=11056"},{"id":685215,"name":"Güneş Dil Teorisi","url":"https://www.academia.edu/Documents/in/Gunes_Dil_Teorisi?f_ri=11056"},{"id":1209290,"name":"Elon Musk","url":"https://www.academia.edu/Documents/in/Elon_Musk?f_ri=11056"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_3029649" data-work_id="3029649" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/3029649/Theoretical_Orbits_of_Planets_in_Binary_Star_Systems">Theoretical Orbits of Planets in Binary Star Systems</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest">Stable S-type and P-type planetary orbits in binary star systems.

As a counterpoint to the fabric of reality his visions of the virtual worlds were hauntingly sketched well ahead of their realisation.","downloadable_attachments":[{"id":31016661,"asset_id":3088933,"asset_type":"Work","always_allow_download":false},{"id":31015475,"asset_id":3088933,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":3495113,"first_name":"Richard","last_name":"Grosser","domain_name":"cpit","page_name":"RichardGrosser","display_name":"Richard Grosser","profile_url":"https://cpit.academia.edu/RichardGrosser?f_ri=11056","photo":"https://0.academia-photos.com/3495113/1191620/1493141/s65_richard.grosser.png"}],"research_interests":[{"id":110,"name":"Gnosticism","url":"https://www.academia.edu/Documents/in/Gnosticism?f_ri=11056","nofollow":true},{"id":422,"name":"Computer Science","url":"https://www.academia.edu/Documents/in/Computer_Science?f_ri=11056","nofollow":true},{"id":721,"name":"Magnetohydrodynamics","url":"https://www.academia.edu/Documents/in/Magnetohydrodynamics?f_ri=11056","nofollow":true},{"id":1372,"name":"Architecture","url":"https://www.academia.edu/Documents/in/Architecture?f_ri=11056","nofollow":true},{"id":2417,"name":"Planetary Science","url":"https://www.academia.edu/Documents/in/Planetary_Science?f_ri=11056"},{"id":7322,"name":"Mysticism","url":"https://www.academia.edu/Documents/in/Mysticism?f_ri=11056"},{"id":7370,"name":"Symbolism","url":"https://www.academia.edu/Documents/in/Symbolism?f_ri=11056"},{"id":8102,"name":"Futurism","url":"https://www.academia.edu/Documents/in/Futurism?f_ri=11056"},{"id":8694,"name":"Science Fiction","url":"https://www.academia.edu/Documents/in/Science_Fiction?f_ri=11056"},{"id":11049,"name":"Extragalactic Astronomy","url":"https://www.academia.edu/Documents/in/Extragalactic_Astronomy?f_ri=11056"},{"id":11056,"name":"Exoplanets","url":"https://www.academia.edu/Documents/in/Exoplanets?f_ri=11056"},{"id":11152,"name":"Sufism","url":"https://www.academia.edu/Documents/in/Sufism?f_ri=11056"},{"id":14096,"name":"Proclus","url":"https://www.academia.edu/Documents/in/Proclus?f_ri=11056"},{"id":15839,"name":"Dead Sea Scrolls Nag Hammadi Codices","url":"https://www.academia.edu/Documents/in/Dead_Sea_Scrolls_Nag_Hammadi_Codices?f_ri=11056"},{"id":23179,"name":"Astrophysics","url":"https://www.academia.edu/Documents/in/Astrophysics?f_ri=11056"},{"id":23483,"name":"Neoplatonism","url":"https://www.academia.edu/Documents/in/Neoplatonism?f_ri=11056"},{"id":23560,"name":"Solar Physics","url":"https://www.academia.edu/Documents/in/Solar_Physics?f_ri=11056"},{"id":36931,"name":"Iamblichus","url":"https://www.academia.edu/Documents/in/Iamblichus?f_ri=11056"},{"id":60357,"name":"Western Esotericism","url":"https://www.academia.edu/Documents/in/Western_Esotericism?f_ri=11056"},{"id":69384,"name":"Stellar Physics","url":"https://www.academia.edu/Documents/in/Stellar_Physics?f_ri=11056"},{"id":79747,"name":"Colonisation","url":"https://www.academia.edu/Documents/in/Colonisation?f_ri=11056"},{"id":86641,"name":"Hermeticism","url":"https://www.academia.edu/Documents/in/Hermeticism?f_ri=11056"},{"id":159232,"name":"Applied Sciences","url":"https://www.academia.edu/Documents/in/Applied_Sciences?f_ri=11056"},{"id":248579,"name":"Planetary Sciences","url":"https://www.academia.edu/Documents/in/Planetary_Sciences?f_ri=11056"},{"id":482071,"name":"art and artists of the Decadent and Symbolist movements","url":"https://www.academia.edu/Documents/in/art_and_artists_of_the_Decadent_and_Symbolist_movements?f_ri=11056"},{"id":938985,"name":"Hermetic Corpus","url":"https://www.academia.edu/Documents/in/Hermetic_Corpus?f_ri=11056"},{"id":938986,"name":"Henotheism","url":"https://www.academia.edu/Documents/in/Henotheism?f_ri=11056"},{"id":958293,"name":"Solar Terrestrial Physics","url":"https://www.academia.edu/Documents/in/Solar_Terrestrial_Physics?f_ri=11056"},{"id":958299,"name":"Cosmic Gamma Ray Bursts","url":"https://www.academia.edu/Documents/in/Cosmic_Gamma_Ray_Bursts?f_ri=11056"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_44690323" data-work_id="44690323" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/44690323/Dalluniverso_infinito_allinfinit%C3%A0_degli_universi_Gli_orizzonti_scientifici_e_cosmologici_contemporanei">Dall'universo infinito all'infinità degli universi?

These neighboring nomadic planets will provide a new exoplanet population for astronomical research and, eventually, direct exploration by spacecraft.","downloadable_attachments":[{"id":36110495,"asset_id":9305518,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":6529577,"first_name":"Marshall","last_name":"Eubanks","domain_name":"mit","page_name":"MarshallEubanks","display_name":"Marshall Eubanks","profile_url":"https://mit.academia.edu/MarshallEubanks?f_ri=11056","photo":"https://0.academia-photos.com/6529577/2621528/18215157/s65_marshall.eubanks.jpg"}],"research_interests":[{"id":701,"name":"Radio Astronomy","url":"https://www.academia.edu/Documents/in/Radio_Astronomy?f_ri=11056","nofollow":true},{"id":704,"name":"Infrared Astronomy","url":"https://www.academia.edu/Documents/in/Infrared_Astronomy?f_ri=11056","nofollow":true},{"id":11056,"name":"Exoplanets","url":"https://www.academia.edu/Documents/in/Exoplanets?f_ri=11056","nofollow":true},{"id":17147,"name":"Brown Dwarfs","url":"https://www.academia.edu/Documents/in/Brown_Dwarfs?f_ri=11056","nofollow":true},{"id":39286,"name":"Exoplanet detection","url":"https://www.academia.edu/Documents/in/Exoplanet_detection?f_ri=11056"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_40322118" data-work_id="40322118" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/40322118/Searching_for_New_Earth">Searching for New Earth</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">The discovery of exoplanets has intensified interest in the search for extraterrestrial life, especially for planets orbiting the sun like stars in habitable zone.

Transit timing effects have been formerly identified as a potent tool to this end, exploiting the dynamics of the system. In this work, we explore the simulation of transit light curves of a planet plus a single moon including not only the transit timing effects but also the light curve signal of the moon itself. We introduce our new algorithm, LUNA, which produces transit light curves for both bodies, analytically accounting for shadow overlaps, stellar limb darkening and planet-moon dynamical motion. By building the dynamics into the core of LUNA, the routine automatically accounts for transit timing/duration variations and ingress/egress asymmetries for not only the planet, but also the moon. We then generate some artificial data for two feasibly detectable hypothetical systems of interest: a i) prograde and ii) retrograde Earth-like moon around a habitable-zone Neptune for a M-dwarf system. We fit the hypothetical systems using LUNA and demonstrate the feasibility of detecting these cases with Kepler photometry.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/874922" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="c9bd3a37c52b7476718e3569ad038d6b" rel="nofollow" data-download="{"attachment_id":5288405,"asset_id":874922,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/5288405/download_file?st=MTczOTgwMDAyMSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="58042" href="https://harvard.academia.edu/DavidKipping">David Kipping</a><script data-card-contents-for-user="58042" type="text/json">{"id":58042,"first_name":"David","last_name":"Kipping","domain_name":"harvard","page_name":"DavidKipping","display_name":"David Kipping","profile_url":"https://harvard.academia.edu/DavidKipping?f_ri=11056","photo":"https://0.academia-photos.com/58042/16968/115518/s65_david.kipping.png"}</script></span></span></li><li class="js-paper-rank-work_874922 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="874922"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 874922, container: ".js-paper-rank-work_874922", });

One technique to detect these distant worlds is through the direct detection of their thermal emission. The so-called direct imaging technique, is suitable for observing young planets far from their star. These are very low signal-to-noise-ratio (SNR) measurements and limited ground truth hinders the use of supervised learning approaches. In this paper, we combine deep generative and discriminative models to bypass the issues arising when directly training on real data. We use a Generative Adversarial Network to obtain a suitable dataset for training Convolutional Neural Network classifiers to detect and locate planets across a wide range of SNRs. Tested on artificial data, our detectors exhibit good predictive performance and robustness across SNRs. To demonstrate the limits of the detectors, we provide maps of the precision and recall of the model per pixel of ...</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/72052582" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="8db762c33f52cffc9386bb919de14986" rel="nofollow" data-download="{"attachment_id":81138970,"asset_id":72052582,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/81138970/download_file?st=MTczOTgwMDAyMSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="145609436" href="https://independent.academia.edu/NIKOSNIKOLAOU18">NIKOS NIKOLAOU</a><script data-card-contents-for-user="145609436" type="text/json">{"id":145609436,"first_name":"NIKOS","last_name":"NIKOLAOU","domain_name":"independent","page_name":"NIKOSNIKOLAOU18","display_name":"NIKOS NIKOLAOU","profile_url":"https://independent.academia.edu/NIKOSNIKOLAOU18?f_ri=11056","photo":"https://0.academia-photos.com/145609436/50120117/38119033/s65_nikos.nikolaou.png"}</script></span></span></li><li class="js-paper-rank-work_72052582 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="72052582"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 72052582, container: ".js-paper-rank-work_72052582", });

One technique to detect these distant worlds is through the direct detection of their thermal emission. The so-called direct imaging technique, is suitable for observing young planets far from their star. These are very low signal-to-noise-ratio (SNR) measurements and limited ground truth hinders the use of supervised learning approaches. In this paper, we combine deep generative and discriminative models to bypass the issues arising when directly training on real data. We use a Generative Adversarial Network to obtain a suitable dataset for training Convolutional Neural Network classifiers to detect and locate planets across a wide range of SNRs. Tested on artificial data, our detectors exhibit good predictive performance and robustness across SNRs. To demonstrate the limits of the detectors, we provide maps of the precision and recall of the model per pixel of ...","downloadable_attachments":[{"id":81138970,"asset_id":72052582,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":145609436,"first_name":"NIKOS","last_name":"NIKOLAOU","domain_name":"independent","page_name":"NIKOSNIKOLAOU18","display_name":"NIKOS NIKOLAOU","profile_url":"https://independent.academia.edu/NIKOSNIKOLAOU18?f_ri=11056","photo":"https://0.academia-photos.com/145609436/50120117/38119033/s65_nikos.nikolaou.png"}],"research_interests":[{"id":422,"name":"Computer Science","url":"https://www.academia.edu/Documents/in/Computer_Science?f_ri=11056","nofollow":true},{"id":465,"name":"Artificial Intelligence","url":"https://www.academia.edu/Documents/in/Artificial_Intelligence?f_ri=11056","nofollow":true},{"id":498,"name":"Physics","url":"https://www.academia.edu/Documents/in/Physics?f_ri=11056","nofollow":true},{"id":854,"name":"Computer Vision","url":"https://www.academia.edu/Documents/in/Computer_Vision?f_ri=11056","nofollow":true},{"id":2008,"name":"Machine Learning","url":"https://www.academia.edu/Documents/in/Machine_Learning?f_ri=11056"},{"id":4095,"name":"Classification (Machine Learning)","url":"https://www.academia.edu/Documents/in/Classification_Machine_Learning_?f_ri=11056"},{"id":5109,"name":"Pattern Recognition","url":"https://www.academia.edu/Documents/in/Pattern_Recognition?f_ri=11056"},{"id":10005,"name":"Applications of Machine Learning","url":"https://www.academia.edu/Documents/in/Applications_of_Machine_Learning?f_ri=11056"},{"id":11056,"name":"Exoplanets","url":"https://www.academia.edu/Documents/in/Exoplanets?f_ri=11056"},{"id":11598,"name":"Neural Networks","url":"https://www.academia.edu/Documents/in/Neural_Networks?f_ri=11056"},{"id":14417,"name":"Machine Vision","url":"https://www.academia.edu/Documents/in/Machine_Vision?f_ri=11056"},{"id":39286,"name":"Exoplanet detection","url":"https://www.academia.edu/Documents/in/Exoplanet_detection?f_ri=11056"},{"id":54123,"name":"Artificial Neural Networks","url":"https://www.academia.edu/Documents/in/Artificial_Neural_Networks?f_ri=11056"},{"id":69100,"name":"Data Science","url":"https://www.academia.edu/Documents/in/Data_Science?f_ri=11056"},{"id":81182,"name":"Deep Learning","url":"https://www.academia.edu/Documents/in/Deep_Learning?f_ri=11056"},{"id":143038,"name":"Machine Learning and Pattern Recognition","url":"https://www.academia.edu/Documents/in/Machine_Learning_and_Pattern_Recognition?f_ri=11056"},{"id":890015,"name":"Deep Neural Networks","url":"https://www.academia.edu/Documents/in/Deep_Neural_Networks?f_ri=11056"},{"id":1433808,"name":"Convolutional Neural Networks","url":"https://www.academia.edu/Documents/in/Convolutional_Neural_Networks?f_ri=11056"},{"id":2655288,"name":"Generative Adversarial Networks","url":"https://www.academia.edu/Documents/in/Generative_Adversarial_Networks?f_ri=11056"},{"id":2923414,"name":"generative adversarial networks (GANs)","url":"https://www.academia.edu/Documents/in/generative_adversarial_networks_GANs_?f_ri=11056"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_45661274" data-work_id="45661274" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/45661274/M%C3%A9todos_Para_la_Detecci%C3%B3n_de_Exoplanetas_METODOS_PARA_LA_DETECCI%C3%93N_DE_EXOPLANETAS">Métodos Para la Detección de Exoplanetas METODOS PARA LA DETECCIÓN DE EXOPLANETAS</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Resumen.

Desde el año 1995 hasta la fecha se llevan descubiertos unos 500 planetas ajenos a nuestro Sistema Solar que orbitan estrellas en nuestro vecindario galáctico. Las técnicas utilizadas en su detección son básicamente tres: la medición de las velocidades radiales, el estudio de los tránsitos planetarios y la Astrometría. Los principios físicos en los que se basan éstas técnicas están al alcance de los estudiantes secundarios del nivel superior. El objetivo de este apunte es mostrar las aplicaciones prácticas de las leyes de Kepler, la ley de Gravitación Universal de Newton, la ley de conservación del Momento Lineal, el efecto Doppler y otros conceptos importantes haciéndolos confluir en un campo apasionante y novedoso de la Astronomía como es el descubrimiento de exoplanetas. 1. Introducción La búsqueda de planetas extrasolares, es decir de planetas que orbitan estrellas distintas al Sol, es un trabajo que comenzó hace escasos 16 años. Antes del año 1995 se tenía por cierto que debían existir muchos otros sistemas planetarios aparte del nuestro, pero en realidad no se tenía ninguna evidencia que validara esta suposición. Pero ese año, la utilización de una serie de nuevos instrumentos y técnicas permitieron dar con el primer planeta extrasolar, 51-Pegasi-b, que orbita a la estrella 51-Pegasi ubicada a unos 50 años-luz de nuestro Sistema Solar. Este planeta está muy lejos y además orbita muy cerca de su estrella por lo que no es posible observarlo en forma directa. Los datos recolectados indicaban que el planeta debía ser masivo pero de una densidad promedio muy baja, lo que implicaba que se trataba de un planeta gigante gaseoso similar en tamaño a nuestro planeta Saturno. El hecho de que un planeta gigante gaseoso orbitara tan cerca de su estrella implicaba un serio cuestionamiento a la teoría de formación de los sistemas planetarios que predice que los planetas gigantes gaseosos sólo pueden formarse lejos de la estrella que orbitan. Esta controversia disparó una revisión de la teoría de formación de los sistemas planetarios y derivó en el planteo de nuevas teorías que aún están siendo debatidas, como por ejemplo la teoría de la migración planetaria. En los años que siguieron fueron descubiertos varios cientos de planetas gigantes gaseosos que orbitan muy cerca de sus respectivas estrellas, demostrando que 51-Pegasi-b no es un caso extraño sino más bien un caso típico. Como la observación directa de exoplanetas-usando telescopios-no es viable debido a las distancias y a que la luz de las estrellas tiende a ocultar a los cuerpos que la orbitan dentro de un cierto radio, las técnicas de detección que se aplican al descubrimiento de planetas extrasolares son indirectas. Entre las técnicas más utilizadas se encuentra el cálculo de la velocidad radial de la estrella a través del análisis del desplazamiento Doppler; la técnica de la detección de tránsitos planetarios, es decir, el paso del planeta por delante de su estrella; y las técnicas de Astrometría que consisten en detectar el "cabeceo" característico de una estrella que es orbitada por un planeta. El presente trabajo reseña cada una de estas técnicas y da las fundamentaciones teóricas respectivas. Se sintetizan en un cuadro comparativo al final del documento, las ventajas y el alcance de cada una de las técnicas mencionadas. El telescopio espacial Hubble y otros telescopios espaciales de nueva generación como el Kepler han permitido desarrollar técnicas observacionales con las que se obtienen los análisis fotométricos de grandes cantidades de estrellas en forma simultánea y automatizada. Estas técnicas facilitan la detección de tránsitos planetarios pero la cantidad de información que se recolecta es tan grande que la comunidad científica está teniendo dificultades para poder analizarla. Esto ha derivado en la elaboración de proyectos de ciencia ciudadana en los que pueden participar estudiantes, profesores y aficionados de todo el mundo. El objetivo de estos proyectos es el de ayudar a la comunidad científica a detectar planetas extrasolares, por medio del análisis de la información acumulada.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/45661274" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="c7b678c4a37e200db5edd0619c2fa9ef" rel="nofollow" data-download="{"attachment_id":66162406,"asset_id":45661274,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/66162406/download_file?st=MTczOTgwMDAyMSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="83533369" href="https://utnfrba.academia.edu/SergioAlonso">Sergio Alonso</a><script data-card-contents-for-user="83533369" type="text/json">{"id":83533369,"first_name":"Sergio","last_name":"Alonso","domain_name":"utnfrba","page_name":"SergioAlonso","display_name":"Sergio Alonso","profile_url":"https://utnfrba.academia.edu/SergioAlonso?f_ri=11056","photo":"https://0.academia-photos.com/83533369/115114270/104398192/s65_sergio.alonso.jpeg"}</script></span></span></li><li class="js-paper-rank-work_45661274 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="45661274"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 45661274, container: ".js-paper-rank-work_45661274", }); });</script></li><li class="js-percentile-work_45661274 InlineList-item InlineList-item--bordered hidden u-tcGrayDark"><span class="percentile-widget hidden"><span class="u-mr2x percentile-widget" style="display: none">•</span><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 45661274; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-percentile-work_45661274"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></li><li class="js-view-count-work_45661274 InlineList-item InlineList-item--bordered hidden"><div><span><span class="js-view-count view-count u-mr2x" data-work-id="45661274"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 45661274; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=45661274]").text(description); $(".js-view-count-work_45661274").attr('title', description).tooltip(); }); });</script></span><script>$(function() { $(".js-view-count-work_45661274").removeClass('hidden') })</script></div></li><li class="InlineList-item u-positionRelative" style="max-width: 250px"><div class="u-positionAbsolute" data-has-card-for-ri-list="45661274"><i class="fa fa-tag InlineList-item-icon u-positionRelative"></i></div><span class="InlineList-item-text u-textTruncate u-pl6x"><a class="InlineList-item-text" data-has-card-for-ri="11056" rel="nofollow" href="https://www.academia.edu/Documents/in/Exoplanets">Exoplanets</a><script data-card-contents-for-ri="11056" type="text/json">{"id":11056,"name":"Exoplanets","url":"https://www.academia.edu/Documents/in/Exoplanets?f_ri=11056","nofollow":true}</script></span></li><script>(function(){ if (false) { new Aedu.ResearchInterestListCard({ el: $('*[data-has-card-for-ri-list=45661274]'), work: {"id":45661274,"title":"Métodos Para la Detección de Exoplanetas METODOS PARA LA DETECCIÓN DE EXOPLANETAS","created_at":"2021-04-01T21:55:39.423-07:00","url":"https://www.academia.edu/45661274/M%C3%A9todos_Para_la_Detecci%C3%B3n_de_Exoplanetas_METODOS_PARA_LA_DETECCI%C3%93N_DE_EXOPLANETAS?f_ri=11056","dom_id":"work_45661274","summary":"Resumen.

EChO -the Exoplanet Characterisation Observatory- is a mission concept specifically geared for this purpose. EChO will provide simultaneous, multi-wavelength spectroscopic observations on a stable platform that will allow very long exposures. EChO will build on observations by Hubble, Spitzer and groundbased telescopes, which discovered the first molecules and atoms in exoplanetary atmospheres. EChO will simultaneously observe a broad enough spectral region -from the visible to the mid-IR- to constrain from one single spectrum the temperature structure of the atmosphere and the abundances of the major molecular species. The spectral range and resolution are tailored to separate bands belonging to up to 30 molecules to retrieve the comp...</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/72437062" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="3071475c9f3a69e304d22e9988fff5a3" rel="nofollow" data-download="{"attachment_id":81361441,"asset_id":72437062,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/81361441/download_file?st=MTczOTgwMDAyMSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="41818925" href="https://ucm.academia.edu/DavidMontes">David Montes</a><script data-card-contents-for-user="41818925" type="text/json">{"id":41818925,"first_name":"David","last_name":"Montes","domain_name":"ucm","page_name":"DavidMontes","display_name":"David Montes","profile_url":"https://ucm.academia.edu/DavidMontes?f_ri=11056","photo":"https://0.academia-photos.com/41818925/28211026/26416912/s65_david.montes.jpg"}</script></span></span></li><li class="js-paper-rank-work_72437062 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="72437062"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 72437062, container: ".js-paper-rank-work_72437062", });

We present the results of N-body simulations which examine the effect such gas giant planet migration has on the formation of terrestrial planets. The models incorporate a 0.5 Jupiter mass planet undergoing type II migration through an inner protoplanet-planetesimal disk, with gas drag included. Each model is initiated with the inner disk being at successively increased levels of maturity, so that it is undergoing either oligarchic or giant impact style growth as the gas giant migrates. In all cases, a large fraction of the disk mass survives the passage of the giant, either by accreting into massive terrestrial planets shepherded inward of the giant, or by being scattered into external orbits. Shepherding is favored in younger disks where there is strong dynamical friction from planetesimals and gas drag is more influential, whereas scattering dominates in more mature disks where dissipation is weaker. In each scenario, sufficient mass is scattered outward to provide for the eventual accretion of a set of terrestrial planets in external orbits, including within the system’s habitable zone. This scattering, however, significantly reduces the density of solid material, indicating that further accretion will occur over very long time scales. A particularly interesting result is the generation of massive, short period, terrestrial planets from compacted material pushed ahead of the giant. These planets are reminiscent of the short period Neptune-mass planets discovered recently, suggesting that such “hot Neptunes” could form locally as a by product of giant planet migration.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/4156599" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="3833571459b3cacc3c03864e853eedca" rel="nofollow" data-download="{"attachment_id":31663104,"asset_id":4156599,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/31663104/download_file?st=MTczOTgwMDAyMSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="5021359" href="https://independent.academia.edu/MartynFogg">Martyn Fogg</a><script data-card-contents-for-user="5021359" type="text/json">{"id":5021359,"first_name":"Martyn","last_name":"Fogg","domain_name":"independent","page_name":"MartynFogg","display_name":"Martyn Fogg","profile_url":"https://independent.academia.edu/MartynFogg?f_ri=11056","photo":"https://0.academia-photos.com/5021359/2182240/2558362/s65_martyn.fogg.jpg"}</script></span></span></li><li class="js-paper-rank-work_4156599 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="4156599"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 4156599, container: ".js-paper-rank-work_4156599", });

Not only may we never receive a signal, we may also never know why. This uncertainty also cautions us against theological speculations about the nature of aliens. Astrotheology is ultimately about us humans; about aliens we can only learn, if at all, through their own free self-disclosure.","downloadable_attachments":[{"id":55232503,"asset_id":35372302,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":2675330,"first_name":"Alfred","last_name":"Kracher","domain_name":"independent","page_name":"AlfredKracher","display_name":"Alfred Kracher","profile_url":"https://independent.academia.edu/AlfredKracher?f_ri=11056","photo":"https://0.academia-photos.com/2675330/853511/1064113/s65_alfred.kracher.jpg"}],"research_interests":[{"id":11056,"name":"Exoplanets","url":"https://www.academia.edu/Documents/in/Exoplanets?f_ri=11056","nofollow":true},{"id":21047,"name":"Theology and Science","url":"https://www.academia.edu/Documents/in/Theology_and_Science?f_ri=11056","nofollow":true},{"id":36271,"name":"SETI (Search for Extraterrestrial Intelligence)","url":"https://www.academia.edu/Documents/in/SETI_Search_for_Extraterrestrial_Intelligence_?f_ri=11056","nofollow":true},{"id":117701,"name":"Human Uniqueness","url":"https://www.academia.edu/Documents/in/Human_Uniqueness?f_ri=11056","nofollow":true},{"id":531200,"name":"Extraterrestrial Life","url":"https://www.academia.edu/Documents/in/Extraterrestrial_Life?f_ri=11056"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_152468" data-work_id="152468" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/152468/A_Search_for_Transiting_Extrasolar_Planets_from_the_Southern_Hemisphere">A Search for Transiting Extrasolar Planets from the Southern Hemisphere</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">To date, more than 300 planets orbiting stars other than our sun have been discovered using a range of observing techniques, with new discoveries occuring monthly.

The work in this thesis focused on the detection of exoplanets using the transit method. Planets orbiting close to their host stars have a roughly 10 per cent chance of eclipsing (transiting) the star, with Jupiter-sized planets causing a one per cent dip in the flux of the star over a few hours. A wealth of orbital and physical information on the system can be extracted from these systems, including the planet density which is essential in constraining models of planetary formation. <br /> <br />To detect these types of planets requires monitoring tens of thousands of stars over a period of months. To accomplish this, we conduct a wide-field survey using the 0.5-meter Automated Patrol Telescope (APT) at Siding Spring Observatory (SSO) in NSW, Australia. Once candidates were selected from the data-set, selection criteria were applied to separate the likely planet candidates from the false-positives. For this thesis, the methods and instrumentation used in attaining data and selecting planet candidates are discussed, as well as the results and analysis of the planet candidates selected from star fields observed from 2004-2007. <br /> <br />Of the 65 planet candidates initially selected from the 25 target fields observed, only two were consistent with a planet transit. These candidates were later determined to be eclipsing binary stars based on follow up observations using the 40-inch telescope, 2.3-m telescope, and the 3.9-m Anglo-Australian Telescope, all located at SSO. Additionally, two planet candidates from the SuperWASP-North consortium were observed on the 40-inch telescope. Both proved to be eclipsing binary stars. While no planets were found, our search methods and results are consistent with successful transit surveys targeting similar fields with stars in a similar magnitude range and using similar methods.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/152468" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="281772a67cc6638c22dde226533db55b" rel="nofollow" data-download="{"attachment_id":34630404,"asset_id":152468,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/34630404/download_file?st=MTczOTgwMDAyMSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="7981" href="https://unimelb.academia.edu/DuaneHamacher">Duane Hamacher</a><script data-card-contents-for-user="7981" type="text/json">{"id":7981,"first_name":"Duane","last_name":"Hamacher","domain_name":"unimelb","page_name":"DuaneHamacher","display_name":"Duane Hamacher","profile_url":"https://unimelb.academia.edu/DuaneHamacher?f_ri=11056","photo":"https://0.academia-photos.com/7981/2871/30236797/s65_duane.hamacher.jpg"}</script></span></span></li><li class="js-paper-rank-work_152468 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="152468"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 152468, container: ".js-paper-rank-work_152468", });

Analysis of huge planetary data from space missions such as CoRoT and Kepler is directed ultimately at finding a planet similar to Earth- the Earth&#39;s twin, and looking for potential habitability. The Earth Similarity Index (ESI) is defined to find the similarity with Earth, which ranges from 1 (Earth) to 0 (totally dissimilar to Earth). ESI can be computed using four physical parameters of a planet, namely radius, density, escape velocity and surface temperature. The surface temperature entering surface ESI is a non-observable quantity and what we know is only equilibrium temperature of exoplanets. We have established a relation between surface and equilibrium temperatures using the data available for the solar system objects to address the difficulty in determining surface temperature. From the ESI analysis, we have found 20 Earth-like exoplanets with ESI value above...</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/68266771" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="8825100608bba8f89e5604e4d67a12c0" rel="nofollow" data-download="{"attachment_id":78803559,"asset_id":68266771,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/78803559/download_file?st=MTczOTgwMDAyMSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="67117599" href="https://christuniversity.academia.edu/MadhuKashyapJagadeesh">Madhu Kashyap Jagadeesh</a><script data-card-contents-for-user="67117599" type="text/json">{"id":67117599,"first_name":"Madhu Kashyap","last_name":"Jagadeesh","domain_name":"christuniversity","page_name":"MadhuKashyapJagadeesh","display_name":"Madhu Kashyap Jagadeesh","profile_url":"https://christuniversity.academia.edu/MadhuKashyapJagadeesh?f_ri=11056","photo":"https://0.academia-photos.com/67117599/17464444/17544324/s65_madhu_kashyap.jagadeesh.jpg"}</script></span></span></li><li class="js-paper-rank-work_68266771 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="68266771"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 68266771, container: ".js-paper-rank-work_68266771", });

To allow for extended in-situ measurements, the spacecraft needs to be decelerated. One of the currently most promising technologies for deceleration is the magnetic sail which uses the deflection of interstellar matter via a magnetic field to decelerate the spacecraft. However, while the magnetic sail is very efficient at high velocities, its performance decreases with lower speeds. This leads to deceleration durations of several decades depending on the spacecraft mass. Within the context of Project Dragonfly, initiated by the Initiative of Interstellar Studies (i4is), this paper proposes a novel concept for decelerating a spacecraft on an interstellar mission by combining a magnetic sail with an electric sail. Combining the sails compensates for each technologys shortcomings: A magnetic sail is more effective at higher velocities than the electric sail and vice versa. It is demonstrated that using both sails sequentially outperforms using only the magnetic or electric sail for various mission scenarios and velocity ranges, at a constant total spacecraft mass. For example, for decelerating from 5% c, to interplanetary velocities, a spacecraft with both sails needs about 29 years, whereas the electric sail alone would take 35 years and the magnetic sail about 40 years with a total spacecraft mass of 8250 kg. Furthermore, it is assessed how the combined deceleration system affects the optimal overall mission architecture for different spacecraft masses and cruising speeds. Future work would investigate how operating both systems in parallel instead of sequentially would affect its performance. Moreover, uncertainties in the density of interstellar matter and sail properties need to be explored.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/28394236" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="bf0a7fc59fe8d00b8ee96ece07edbf4a" rel="nofollow" data-download="{"attachment_id":48731906,"asset_id":28394236,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/48731906/download_file?st=MTczOTgwMDAyMSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="252763" href="https://turn-de.academia.edu/AndreasMHein">Andreas M.

Yet, despite these astronomical advances, there are presently no well-confirmed tests against which to check the design of interstellar messages. In the meantime, the best we can do is distance ourselves from terracentric assumptions. There is no reason, for example, to assume that all inferential abilities are language-like. With that in mind, I argue that logical reasoning does not have to be couched in symbolic notation. In diagrammatic reasoning, inferences are underwritten, not by rules, but by transformations of self-same qualitative signs. I use the Existential Graphs of C. S. Peirce to show this. Since diagrams are less dependent on convention and might even be generalized to cover non-visual senses, I argue that METI researchers should add some form of diagrammatic representations to their repertoire. Doing so can shed light, not just on alien minds, but on the deepest structures of reasoning itself.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/38087949" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="0e4deb8231f7fe1d076cb5a3b40d88b3" rel="nofollow" data-download="{"attachment_id":60312290,"asset_id":38087949,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/60312290/download_file?st=MTczOTgwMDAyMSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="90594" href="https://kwantlen.academia.edu/MarcChampagne">Marc Champagne</a><script data-card-contents-for-user="90594" type="text/json">{"id":90594,"first_name":"Marc","last_name":"Champagne","domain_name":"kwantlen","page_name":"MarcChampagne","display_name":"Marc Champagne","profile_url":"https://kwantlen.academia.edu/MarcChampagne?f_ri=11056","photo":"https://0.academia-photos.com/90594/25175/116736640/s65_marc.champagne.jpg"}</script></span></span></li><li class="js-paper-rank-work_38087949 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="38087949"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 38087949, container: ".js-paper-rank-work_38087949", });

Yet, despite these astronomical advances, there are presently no well-confirmed tests against which to check the design of interstellar messages. In the meantime, the best we can do is distance ourselves from terracentric assumptions. There is no reason, for example, to assume that all inferential abilities are language-like. With that in mind, I argue that logical reasoning does not have to be couched in symbolic notation. In diagrammatic reasoning, inferences are underwritten, not by rules, but by transformations of self-same qualitative signs. I use the Existential Graphs of C. S. Peirce to show this. Since diagrams are less dependent on convention and might even be generalized to cover non-visual senses, I argue that METI researchers should add some form of diagrammatic representations to their repertoire.
