WebApr 23, 2024 · As the star ages, helium accumulates and begins to “burn,” undergoing fusion to form heavier elements such as carbon and oxygen. As the adolescent star matures, significant amounts of iron and nickel are formed by fusion of the heavier elements formed previously. WebWhen a star is fusing iron in its core, it's still giving off insane amounts of energy. The helium, hydrogen, carbon, oxygen, and silicon are still there in the star in different shells.
Webwas taken from Prialnik, Figure 8.6, for a star of seven solar masses. It is assumed that this is a reasonable density for a solar mass star also. Inevitably, the calculations in this Chapter are rough illustrations only. The helium burning phase of a stars evolution is far more complicated than the hydrogen burning phase, as described in ...
