WebA hydrogen burning shell forms around the helium core, and the shell contributes more and more helium to the core over time. Eventually the core becomes hotter and denser and reaches a temperature of 100 million K, and helium nuclei begin to fuse into carbon. The helium fusion then heats the core rapidly even more and a helium flash takes place. WebThis process also fuses four protons into a Helium nucleus, by using Carbon (C), Nitrogen (N) and Oxygen (O) nuclei as catalysts.
