WebTriple Alpha Process. If the central temperature of a star exceeds 100 million Kelvins, as may happen in the later phase of red giants and red supergiants, then helium can fuse … During helium fusion, stars build up an inert core rich in carbon and oxygen. The inert core eventually reaches sufficient mass to collapse due to gravitation, whilst the helium burning moves gradually outward. This decrease in the inert core volume raises the temperature to the carbon ignition temperature. … Meer weergeven 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 These figures for temperature and density are only a … Meer weergeven • Alpha process • Carbon detonation • CNO cycle • Neon-burning process Meer weergeven This sequence of reactions can be understood by thinking of the two interacting carbon nuclei as coming together to form an excited state of the Mg nucleus, … Meer weergeven Neutrino losses start to become a major factor in the fusion processes in stars at the temperatures and densities of carbon burning. Though the main reactions don't involve neutrinos, the side reactions such as the proton–proton chain reaction do. But the main … Meer weergeven
