Red Giant Stars: Facts, Definition & the Future of the Sun

WebAll stars with initial masses up to about eight times that of the Sun will eventually become red giants in the later stages of their lives. They start to cool down and lose a large amount of their mass in a steady, dense wind that streams outwards from the star. WebApr 1, 2024 · All these stars go through a giant phase, He core burning and asymptotic giant branch phases. Above this then carbon burning will be initiated in the core and it is likely that burning will continue through to iron, followed by core-collapse and a supernova.

How do main-sequence stars become giants

WebWhen stars have exhausted all their hydrogen fuel, they evolve to red giants. Their outer layers of gas expand and cool; therefore, the stars move to the right on the H-R diagram. Although a star cools when it becomes a red giant, it grows so large its luminosity (or total power emitted) increases. Therefore, the star also moves up the H-R diagram.
