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. WebThen, when two nuclei of helium fuse with each other, they form the nucleus of another element, beryllium. In turn, the fusion of beryllium with helium produces a carbon nucleus; the fusion of carbon and helium nuclei leads to an oxygen nucleus, and so on. This way, through successive fusion reactions, the nuclei of most elements lighter
