Mostren un fort camp magnètic d’uns quants milers de <a href="/wiki/Gauss_(unitat)" title="Gauss (unitat)">Gauss</a>, que varia a mesura que l'estrella gira des de la perspectiva de la Terra. El lleuger canvi de llum d’un màxim de 0,1 de magnitud aparent és el resultat d’una acumulació química de <a href="/wiki/Silici" title="Silici">silici</a>, <a href="/wiki/Crom" title="Crom">crom</a> i <a href="/wiki/Terra_rara" title="Terra rara">terres rares</a> al voltant dels pols del camp magnètic.</li> <li>Les <a href="/wiki/Variable_BY_Draconis" title="Variable BY Draconis">estrelles BY Draconis</a> són <a href="/wiki/Estel_nan" title="Estel nan">nanes</a> tardanes amb <a href="/wiki/L%C3%ADnia_espectral" title="Línia espectral">línies d'emissió</a> amb un <a href="/wiki/Tipus_espectral" title="Tipus espectral">tipus espectral</a> de dKe a dMe.

La variabilitat és conseqüència de les taques estel·lars i de l’activitat cromosfèrica a causa de la rotació ràpida. A les estrelles <a href="/wiki/Variable_BY_Draconis" title="Variable BY Draconis"> BY Draconis</a>, també s’han observat erupcions solars com les de les estrelles <a href="/wiki/Estrella_fulgurant" title="Estrella fulgurant">UV-Ceti</a>.</li> <li>Les variables <a href="/wiki/Variable_FK_Comae_Berenices" title="Variable FK Comae Berenices">FK Comae Berenices</a> són variables que roten ràpidament amb una brillantor superficial desigual i un tipus espectral de G a K.

Probablement són estrelles simples que han sorgit recentment d’una fusió d’un sistema estel·lar binari proper i on el camp magnètic encara no ha tingut temps d’alentir la rotació. La durada de rotació i el període de canvis de brillantor són inferiors a 5 dies.</li> <li>Els <a href="/wiki/P%C3%BAlsars" class="mw-redirect" title="Púlsars">púlsars</a> són <a href="/wiki/Estrelles_de_neutrons" class="mw-redirect" title="Estrelles de neutrons">estrelles de neutrons</a> que giren ràpidament amb un fort camp magnètic. El temps de rotació oscil·la entre 0,01 i pocs segons. En els púlsars joves, el camp magnètic és suficient per arrencar <a href="/wiki/Electr%C3%B3" title="Electró">electrons</a> de l'escorça de l'estrella de neutrons i accelerar-los al llarg de les línies del camp magnètic.
