carbon burning

(carbon fusion)
(fusion reaction starting with carbon)

Carbon burning is fusion of two carbon nuclei, which takes place in early stars, producing magnesium and oxygen. A carbon-burning shell appears in a sufficiently-massive star during a phase in the asymptotic giant branch, forming after the helium-burning shell and before the neon-burning shell (if the latter forms). Carbon burning requires a temperature on the order of 5 × 108 K.
