Noun
CNO cycle (plural CNO cycles)
carbon-nitrogen-oxygen cycle
During a star's evolution, convective mixing episodes moves material, within which the CNO cycle has operated, from the star's interior to the surface, altering the observed composition of the star. Source: Internet
A self-maintaining CNO chain starts at approximately main, but its energy output rises much more rapidly with increasing temperatures. citation At approximately main, the CNO cycle starts becoming the dominant source of energy. Source: Internet
In heavier stars, the CNO cycle is more important. Source: Internet
In stars of slightly over convert, the carbon–nitrogen–oxygen fusion reaction ( CNO cycle ) contributes a large portion of the energy generation. Source: Internet
In the Sun, a one solar-mass star, only 1.5% of the energy is generated by the CNO cycle. Source: Internet
Most of the energy produced at Vega's core is generated by the carbon nitrogen oxygen cycle ( CNO cycle ), a nuclear fusion process that combines protons to form helium nuclei through intermediary nuclei of carbon, nitrogen, and oxygen. Source: Internet
