Abstract:

We present a new grid of stellar models from 0.8 to tex2html_wrap_inline1053 at Z=0.10, with mass loss and moderate overshooting, from the zero age main sequence to either the helium flash (low mass stars), the early AGB phase (intermediate-mass stars) or the end of carbon burning (massive stars). The calculations are done with opacities provided by Iglesias & Rogers (1993), completed by those of Alexander & Ferguson (1994) at low temperatures. This grid is a homogeneous extension to very high metallicity of the previous grids published by the Geneva group. It is useful for the study of galactic bulges, elliptical galaxies and eventually quasars. Calculations of stars more massive than tex2html_wrap_inline1053 are not presented as these objects lose almost their entire mass during their main sequence phase, and are likely to end their life as white dwarfs.
