oxygen burning
(fusion reaction starting with oxygen)
Oxygen burning is fusion of two oxygen nuclei,
along with some subsequent reactions, which
takes place in early stars, and produces silicon,
phosphorus, sulfur, and magnesium.
An oxygen-burning shell
appears in a sufficiently-massive star during a phase while in the
asymptotic giant branch (AGB). According to one common model, it forms after the
neon-burning shell and before the silicon-burning shell
(if the latter forms). Oxygen burns after neon because it
requires a higher temperature (on the order of 109
K): an oxygen nucleus is more stable and more kinetic energy is required
to bring the nuclei together.
