Contrairement à ce que l'on entend parfois, il ne s'agit pas de l'explosion d'une étoile, mais plutôt d'un corps à corps entre les deux étoiles d'un système binaire : une naine blanche et une géante rouge. La première, vestige compact d'une étoile ayant épuisé la majorité de son carburant nucléaire, dévore littéralement sa compagne en fin de vie, dont l'atmosphère enfle, symptôme qu'elle est entrée dans une lente agonie.</p><div><span class="Capsule free"><span class="Phylactery">À LIRE AUSSI</span> <strong class="strong"><a href="https://www.lepoint.fr/astronomie/pourquoi-la-rotation-de-la-terre-pourrait-nous-priver-d-une-seconde-29-03-2024-2556319_1925.php" title="Pourquoi la rotation de la Terre pourrait nous priver d'une seconde" style="text-decoration: none; color: inherit;" data-gtm="click:capsule" data-capsule="À lire aussi">Pourquoi la rotation de la Terre pourrait nous priver d'une seconde</a></strong></span></div><p>Que se passe-t-il alors concrètement ? La matière expulsée par la géante rouge est capturée par la naine blanche jusqu'à ce que la chaleur et la pression à la surface de cette dernière atteignent un point critique à partir duquel se déclenche une explosion thermonucléaire. C'est ainsi que l'étoile binaire T Coronae Borealis, habituellement invisible dans notre ciel, sera sans doute bientôt aussi brillante que l'étoile Polaire.</p><section class="mbl txtcenter"><div id="IN_CONTENT_SCROLL" class="txtcenter mbs slotpub"></div></section><div class="mts"><div class="reset-text mtm mbm"><div class="art-twitter"> <blockquote class="twitter-tweet-unloaded" data-media-max-width="560"> <p dir="ltr" lang="fr">Animation de la nova attendue de l’étoile binaire T Coronae Borealis, qui devrait bientôt apparaître dans le ciel et être visible à l'oeil nu dans la Couronne Boréale.<br /> ��NASA’s Goddard Space Flight Center <a href="https://t.co/se2R3S5nCC">pic.twitter.com/se2R3S5nCC</a></p> — Philippe Berry (@ptiberry) <a href="https://twitter.com/ptiberry/status/1783638214366105935?ref_src=twsrc%5Etfw">April 25, 2024</a> </blockquote> </div></div></div><h2>Tango stellaire</h2><p>Mais comment le sait-on ? Tout simplement parce que, plus qu'une apparition, il s'agit de la réapparition d'un astre ayant passé près d'un siècle dans l'ombre. En effet, c'est un événement rare mais récurrent. Observé en 1946 et en 1886, on retrouve sa trace jusqu'au XIII<sup>e</sup> siècle environ. Il faut dire que les étoiles ne meurent pas en un jour… Ainsi, la danse macabre du couple infernal de la Couronne boréale dure-t-elle depuis bien longtemps, une nova y explosant tous les quatre-vingts ans environ.</p><APP_ONLY><JEU ID="3" TYPE="BON_NOMBRE"/></APP_ONLY><p>Or tout semble indiquer que cela devrait se reproduire très bientôt, probablement entre aujourd'hui même et le mois de septembre prochain. Nul ne peut dire précisément quand. C'est donc en quelque sorte le feuilleton astronomique du printemps, voire de l'été qui vient. Les astronomes, professionnels et amateurs, sont à l'affût pour l'étudier et le public, même le moins expérimenté, peut facilement participer à la fête en guettant, à l'œil nu, le sursaut de luminosité rendant d'un coup l'astre invisible très brillant. Un flamboiement qui ne devrait durer qu'une semaine à partir de son déclenchement.</p><p><span class="Capsule discover-kangourou"> <span class="Phylactery">À Découvrir</span> <strong class="discover-kangourou__line"> <img class="discover-kangourou__img" src="https://static.lpnt.fr/static/img/kangourou/kangourou_filled.svg" /> <strong class="discover-kangourou__txt"> <strong>Le Kangourou du jour</strong> <a href="https://kangourou.lepoint.fr" title="kangourou" data-gtm-cta="kangourou_article" class="discover-kangourou__lnk"> Répondre </a> </strong> </strong> </span><div class="FirstMedia NoBorder middle"><figure class="Figure"><img src="https://static.lpnt.fr/images/2024/04/26/26412905lpw-26413036-embed-libre-jpg_10265851.jpg" loading="lazy" width="809" height="562" alt="Position de la Couronne boréale – où doit se produire la nova – dans le ciel d'Île-de-France, samedi 27 avril vers 23 heures. © Image générée grâce au logiciel gratuit Stellarium"><figcaption class="Figcaption"><span class="description">Position de la Couronne boréale – où doit se produire la nova – dans le ciel d'Île-de-France, samedi 27 avril vers 23 heures. </span><span> © Image générée grâce au logiciel gratuit Stellarium</span></figcaption></figure></div></p><div class="BeOpWidget"></div><p>L'avantage est que la Couronne boréale est parfaitement visible dans le ciel à cette saison et également assez facile à repérer. Il est ainsi tout à fait possible d'y jeter un coup d'œil chaque soir pour voir si le « feu d'artifice » a commencé. Une expérience que l'on ne peut espérer tenter qu'une seule fois dans une vie. Durant le week-end qui vient, vous trouverez facilement la Couronne boréale bien haut dans le ciel en vous tournant vers l'est aux alentours de 23 heures. Des applications et des logiciels, y compris gratuits, peuvent facilement vous aider à la suivre dans le ciel pendant toute la saison. C'est une occasion à ne pas manquer.</p> <div id="paywall-poool-article-gratuit"></div> </div> <div class="article-tags"> <h3 class="article-tags__title">Les mots-clés associés à cet article</h3> <ul class="article-tags__list"><li><a href="/tags/lettre-espace" >La lettre de l'espace</a></li></ul></div><section id="ne-pas-manquer" class="title-top"> <h2>À ne pas manquer</h2> <ul> <li> <h3 class="ListItem Premium"> <a href="/science/dieu-et-la-science-a-chacun-sa-verite-10-09-2023-2534881_25.php" data-gtm-article="A ne pas manquer"> Dieu et la science : à chacun sa vérité !</a> </h3> </li> <li> <h3 class="ListItem"> <a href="/astronomie/comment-les-etoiles-massives-voisines-faconnent-les-systemes-planetaires-29-02-2024-2553911_1925.php" data-gtm-article="A ne pas manquer"> Comment les étoiles massives voisines façonnent les systèmes planétaires</a> </h3> </li> <li> <h3 class="ListItem"> <a href="/eureka/qu-est-ce-que-les-quasars-dont-la-mission-gaia-a-etabli-une-liste-25-03-2024-2555880_4706.php" data-gtm-article="A ne pas manquer"> Astronomie : quasar, vous avez dit quasar ?</a> </h3> </li> </ul> </section>        <div id="taboola-below-article"></div> <script type="text/javascript"> window._taboola = window._taboola || []; _taboola.push({ mode: 'thumbnails-a', container: 'taboola-below-article', placement: 'Below Article', target_type: 'mix' }); </script> <style> #taboola-below-article-split-num-1 { min-height: 3583px; } </style>     <section id="commentaires"> <template id="form-commentaire-abusif"> <form class="commentaire-abusif" action="#" method="post"> <p class="titre">Signaler un contenu abusif</p> <label for="motif">Merci de nous préciser le motif <sup>*</sup></label> <textarea title="Motif" id="motif" maxlength="1200" cols="5" rows="3" name="text" placeholder="Écrire votre motif (1200 caractères maximum)"></textarea> <div class="chars-limit"> <p> <span class="nb">0</span> / <span class="max">1200</span> </p> </div> <label for="captcha_code">Veuillez saisir le code de sécurité ci-dessous <sup>*</sup> : </label> <input name="usercaptcha" id="captcha_code" type="text" value="" placeholder="Code de sécurité"> <input type="hidden" name="idcaptcha"> <p class="error" style="display:none;">Code erroné</p> <div class="captcha_img"></div> <input type="hidden" name="id_commentaire" value=""> <input type="hidden" name="action" value="reportCommentaire"> <div class="btn-container"> <button type="submit" class="btn">Envoyer</button> <button data-vote="" class="btn annuler">Annuler</button> </div> </form> </template> <aside class="paywall" data-ifnot-premium="block"> <div class="paywall-content"> <p class="titre">Un avis, un commentaire ?</p> <p>Partagez votre opinion avec les autres membres du Point.</p> <a href="https://abo.lepoint.fr?provenance=01EDI020077" class="btn" data-campaign="paywall_commentaire" data-gtm="click:paywall-abo">S'abonner</a> <button class="swg-standard-button" id="swg-btn-maison2" role="button" title="S'abonner avec Google" data-gtm="click:paywall-swg"></button> </div> </aside> <div class="info-paywall">Ce service est réservé aux abonnés. <a href="https://moncompte.lepoint.fr/connexion/?return">S’identifier</a></div> <div data-if-blacklisted="block" class="banni"> <div class="msg">Vous ne pouvez plus réagir aux articles suite à la soumission de contributions ne répondant pas à la charte de modération du Point.</div> <div class="liens"> <a href="/html/cgu/">Je consulte la charte de modération</a> <a href="/html/contact/">Je contacte les services de modération</a> </div> </div> <div data-if-cancomment="block" class="message" style="display:none;"></div> <div id="form-add-comment" data-if-cancomment="block"> <header> <span data-user-pseudo></span> </header> <textarea title="Le texte du commentaire est obligatoire" maxlength="2000" cols="5" rows="5" name="commentary" placeholder="Écrire un commentaire (2 000 caractères maximum)"></textarea> <div class="chars-limit"> <p> <span class="nb">0</span> / <span class="max">2000</span> </p> </div> <div class="alert-me"> <input id="alerted-bymail" type="checkbox" checked="checked" value="true" name="emailConfirm"> <label for="alerted-bymail">M'alerter lors de la publication de ma réaction</label> <input type="hidden" name="url" value="/astronomie/alerte-a-la-nova-une-etoile-va-bientot-reapparaitre-dans-le-ciel-26-04-2024-2558757_1925.php"/> <input type="hidden" name="token" value="67b425dfbe57c" /> <input type="hidden" name="id_sans_version" value="2558757" /> <input type="hidden" name="titre_article" data-vh="ueii" value="Alerte à la nova !
