Evolutionary sequences of stellar models with very high metallicity. V. Z=0.1

1994
We present detailed tabulations of a large grid of stellar models with initial chemical compositions [Y = 0.475, Z = 0.1] computed with the radiative opacities by Huebner et al. (1977) and convective overshoot. This choice of the opacity is due to the high metallicity in use, because the Livermore Library of radiative opacities (Iglesias et al.

Evolutionary sequences of stellar models with semiconvection and convective overshoot. I. Z=0.008.

1993
We present two grids of evolutionary stellar models covering the phases of core H- and He-burning for stars having masses in the range 0.6M. to 100M. with composition (Y = 0.25 and Z = 0.008). The computations were performed for two different mixing schemes in the convective regions, i.e.

Evolutionary sequences of stellar models with new radiative opacities. IV. Z=0.004 and Z=0.008

1994
We present detailed tabulations of two large grids of stellar models with the initial chemical compositions [Y=0.240, Z=0.004] and [Y=0.250, Z=0.008], computed with the most recent radiative opacities (OPAL) by Iglesias et al. (1992). This paper continues the series initiated by Bressan et al.

Evolutionary sequences of stellar models with new radiative opacities. III. Z=0.0004 and Z=0.05

1994
We present detailed tabulations of two large grids of stellar models with the extreme initial chemical composition [Z=0.0004, Y=0.230], and [Z=0.050, Y=0.352]. The models are computed with the most recent radiative opacities (OPAL) by Iglesias et al.
