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), which is more efficient at the Sun 's core te...
CNO cycle, sequence of thermonuclear reactions that provides most of the energy radiated by the hotter stars. It is only a minor source of energy for the Sun and does not operate at all in very cool stars. Four hydrogen nuclei are in effect converted into one helium nucleus, a fraction of the mass.

The ‘ CNO cycle’ refers to the Carbon-Nitrogen- Oxygen cycle, a process of stellar nucleosynthesis in which stars on the Main Sequence fuse hydrogen into helium via a six-stage sequence of reactions. This sequence proceeds as follows: A carbon-12 nucleus captures a proton and emits a gamma ray, producing nitrogen-13.
Der Bethe-Weizsäcker-Zyklus (auch CN-Zyklus, CNO-Zyklus, CNO-I-Zyklus, Kohlenstoff-Stickstoff-Zyklus) ist eine der acht Fusionsreaktionen des so genannten Wasserstoffbrennens, durch die Sterne Wasserstoff in Helium umwandeln; die anderen sind die Proton-Proton-Reaktion sowie weitere mögliche CNO-Zyklen, die allerdings bei noch ...
In higher-mass stars, the dominant energy production process is the CNO cycle, which is a catalytic cycle that uses nuclei of carbon, nitrogen and oxygen as intermediaries and in the end produces a helium nucleus as with the proton-proton chain. CNO reaction is a very temperature sensitive process. [3] .
CNO cycle explained. 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), which is more ...
25. Nov. 2020 · Since the 1930s it has been theorised that stars have a specific fusion reaction known as the CNO cycle, but proof has been elusive. Now, a collaboration in Italy report...
