It is shown that the most important source of energy in ordinary stars is the reactions of carbon and nitrogen with protons. These reactions form a cycle in which the original nucleus is reproduced, viz. C12+H=N13, N13=C13+e+, C13+H=N14, N14+H=O15, O15=N15+e+, N15+H=C12 +He4. Thus carbon and nitrogen merely serve as catalysts for the combination of four protons (and two electrons) into an α-particle (§7). The carbon-nitrogen reactions are unique in their cyclical character (§8). For all nuclei… Expand
