CNO-siklus

Die CNO-siklus is 'n kringloop van kernreaksies wat in sterre plaasvind wat 'n massa groter as 1,1 sonmassas besit. In hierdie kringloop word protium in helium omgesit volgens:[1]

4\ ^{1}H^{+}\to \ ^{4}He^{2+}+4\gamma +2e^{+}+2\nu

Die CNO-siklus

Die siklus betref nogtans kerne van koolstof, stikstof en suurstof. Dit begin met ¹²₆C. Reaksie met 'n proton vereis 'n temperatuur bokant 16 miljoen Kelvin.
