WebThe CNO cycle (for carbon-nitrogen-oxygen), or sometimes Bethe-Weizsäcker-cycle, is one of two fusion reactions by which stars convert hydrogen to helium, the other being the proton-proton chain.. The proton-proton chain is more important in stars the mass of the sun or less. Only 1.7% of 4 He nuclei being produced in the Sun are born in the CNO cycle. … WebNov 25, 2024 · The second process is the CNO cycle, which was proposed independently in 1938 by Hans Bethe and Carl Friedrich von Weizsacker. It is believed to account for about 1% of fusion energy in Sun-sized stars — but is thought to …
