Abstract:
We present a detailed study of the evolution of massive stars of
masses 15, 20, 25, and 30M☉ assuming solar-like initial chemical
composition. The stellar sequences were evolved through the advanced
burning phases up to the end of core oxygen burning. We present a
careful analysis of the physical characteristics of the stellar
models. In particular, we investigate the effect of the
still-unsettled reaction 12C(α,γ)16O on the advanced
evolution by using recent compilations of this rate.
