The CNO cycle (for carbon–nitrogen–oxygen; sometimes called Bethe–Weizsäcker cycle after Hans Albrecht Bethe and Carl Friedrich von Weizsäcker) is one of the two known sets of fusion reactions by which stars convert hydrogen to helium, the other being the proton–proton chain reaction (p–p cycle), … See more Under typical conditions found in stars, catalytic hydrogen burning by the CNO cycles is limited by proton captures. Specifically, the timescale for beta decay of the radioactive nuclei produced is faster than the timescale … See more Under conditions of higher temperature and pressure, such as those found in novae and X-ray bursts, the rate of proton captures exceeds the rate of beta-decay, pushing the burning to the proton drip line. The essential idea is that a radioactive species will capture … See more • Bethe, H. A. (1939). "Energy Production in Stars". Physical Review. 55 (5): 434–56.

WebLe cycle carbone-azote-oxygène(ou, avec les symboles chimiques, cycle CNO), parfois appelé cycle de Bethe, ou cycle de Bethe-Weizsäcker[1], est l'une des deux réactions de fusion nucléairepar lesquelles les étoilesconvertissent de l'hydrogèneen hélium ; l'autre réaction est la chaîne proton-proton.
