Abstract:
Most outputs of massive star evolution critically depend on the mass
loss rates. In order to broaden the comparison basis and to illustrate
the effects of different mass loss rates, we have computed new sets of
models, with initial masses between 12 and 120 M☉, and
metallicities, Z, between 0.001 and 0.040, with a mass loss rate
increased by a factor of two during the phases when the stellar winds
are believed to be essentially driven by the radiation pressure. A
moderate core-overshooting and the new radiative opacities from
Iglesias et al. (1992ApJ...397..717I 1992ApJ...397..717I) and Kurucz (1991) were taken
into account. These models complete the homogeneous and extended
theoretical database formed by the previous grids of this series,
computed by Schaller et al. (1992, Cat. J/A+AS/96/269) for Z=0.020 and
Z=0.001, by Schaerer et al. (1992, Cat. J/A+AS/98/523; 1993, Cat.
J/A+AS/102/339) for Z=0.008 and Z=0.040 and by Charbonnel et al.
(1993, Cat. J/A+AS/101/415) for Z=0.004. This paper closes this
series. Of particular interest is the predicted behaviour of metal
rich stars such as may be found in the inner regions of our Galaxy.
New evolutionary connexions are found, in particular we show that the
most massive and metal rich stars may spend a relatively long time as
He and N enriched stars and may even end their evolution as white
dwarfs.
