The CNO Cycle: Advanced Connections

The carbon-nitrogen-oxygen cycle is a hydrogen-fusion network in which carbon, nitrogen, and oxygen nuclei act primarily as catalysts while protons are converted into helium. The CNO cycle explains energy production and interior structure in massive main-sequence stars, contributes to stellar neutrino science, and alters carbon, nitrogen, and oxygen isotope ratios in processed stellar material.

CNO reactions involve larger nuclear charges than proton-proton reactions, so they require more energetic collisions and are extremely temperature-sensitive.
