1 When a star exhausts the hydrogen in its core, it becomes a giant or supergiant. 2  sun become hot enough to fuse helium into carbon. 3  sun become hot enough to fuse carbon into heavier elements.
Once all the hydrogen in the core has been converted to helium by nuclear fusion, there is no energy outflow to counter the inward force of gravity and the star rapidly collapses. This in turn heats the core and the region around it to such an extent that hydrogen fusion begins in the outer layers.
