Abstract
We present a large grid of stellar evolutionary models with the initia l chemical composition [Z = 0.0001, Y = 0.23]. These tracks are concei ved to extend the grid of stellar models described in the previous pap ers of this series, and are computed with the new radiative opacities by Iglesias et al. (1992) and convective overshoot. The tracks span th e range of initial masses from 0.6 M. to 100 M., and extend from the z ero age main sequence (ZAMS) till very advanced evolutionary phases. S pecifically, low- and intermediate-mass stars are followed till the be ginning of the thermally pulsing regime of the asymptotic red giant br anch phase (TP-AGB), while massive stars are followed till the core C- ignition. With respect to previous papers of this series, these models incorporate a number of small modifications in the input physics, par ticularly on the equation of state, which now incorporates the effect of Coulomb interactions between charged particles. The effect of these modifications is discussed. The corresponding theoretical isochrones are presented.
