Stellar Evolution: Massive Stars, Stellar Evolution: Opacities
Scientific paper
The authors compute the theoretical evolution of a massive and an intermediate-mass star through main sequence and core He-burning phase with the most recent radiative opacities. The computations are performed by adopting a moderate nonlocal overshoot from the convective region. The use of overshooting produces appreciable variation of the evolutionary paths in the HR diagram, the duration of the central H- and He-burning phases, and the characteristics of the H-shell burning stage when compared with the results derived under classical convection conditions. It is noticed that the Tc-ρc relation of intermediate-mass stars is very sensitive to the use of overshooting. The authors discuss these results theoretically.
