It usually happens when its nuclear fusion cannot hold the core against its own gravity. [1] The core collapses, and explodes. The biggest stars that make supernovae are hypergiants and smaller ones are supergiants. They are massive: because of gravity, they use up their energy very quickly.

WebSupernovele sunt extrem de luminoase și cauzează o explozie de radiații care adesea este mai strălucitoare decât o întreagă galaxie, înainte de a dispărea după câteva săptămâni sau luni. De-a lungul acestui interval, o supernovă poate radia tot atâta energie cât ar putea emite Soarele pe toată durata sa de viață. [1] Web23 feb 2024 · For a Type 1A supernova, you need to have at least a binary star system. The white dwarf accretes matter from the other star until it builds up enough mass to trigger the supernova. So for a Sun like star to ever produce a type 1A supernova, it has to have a companion star. The picture is utterly confusing.

WebA type Ia supernova is a type of supernova that occurs in binary systems (two stars orbiting one another) in which one of the stars is a white dwarf. The other star can be anything from a giant star to an even smaller white dwarf. Physically, carbon - oxygen white dwarfs with slow rotation are limited to below 1.44 solar masses.
