Carbon-burning process - Wikipedia
The carbon-burning process or carbon fusion is a set of nuclear fusion reactions that take place in the cores of massive stars (at least 8 ⊙ at birth) that combines carbon into other elements. It requires high temperatures (> 5×10 8 K or 50 keV) and densities (> 3×10 9 kg/m 3).. These figures for temperature and density are only a guide. More massive stars burn their nuclear fuel more ...
