Core of a star that glows by stored heat
WebIn a supernova, the star's core collapses and then explodes. In massive stars, a complex series of nuclear reactions leads to the production of iron in the core. Having achieved iron, the star has wrung all the energy it can out of nuclear fusion - fusion reactions that form elements heavier than iron actually consume energy rather than produce it. WebStars that have earned the title of "supergiant" are so massive and so hot that they begin fusing silicon to a solid core of iron. Once the star starts fusing iron, that’s it-- it’s doomed ...

WebFeb 28, 2015 · In fact, fusion acts as a regulator: too much of it and the star expands and cools, slowing down fusion; too little and the star collapses further, heating up more and increasing the fusion rate. In summary, gravitational collapse provides the initial energy to heat a star. As it uses up this energy source, it begins to tap into fusion.
