J/ApJ/611/452         Evolution of massive stars                 (El Eid+, 2004)

Evolution of massive stars up to the end of central oxygen burning. El Eid M.F., Meyer B.S., The L.-S. <Astrophys. J., 611, 452-465 (2004)> =2004ApJ...611..452E

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. File Summary:
