The next step would be fusing iron into some heavier element but doing so requires energy instead of releasing it. The star’s iron core collapses until forces between the nuclei push the brakes, then it rebounds.

WebJun 27, 2014 · As Joan.bdm pointed out, stars have an interior volume, the burning zone down towards the core in which the pressures are high enough for fusion to take place. Probably should call it the burning volume The burning volume is the volume in which fusion can occur. Fusion occurs once a specific threshold of heat and pressure have been reached. http://sunshine.chpc.utah.edu/Labs/StarLife/oldstars.html
WebSo, do stars actually burn out? It isn’t as simple as losing their heat, but stars can eventually burn out due to a particular catastrophic event.

But the main one is that the forces that balance out this giant object fall into an imbalance. Here’s how NASA explains it: “Massive stars burn huge amounts of nuclear fuel at their cores, or centers. This produces tons of energy, so the center gets very hot.
