Grids of stellar models. VI. Horizontal branch and early asymptotic giant branch for low mass stars (Z=0.020, 0.001).
Abstract
New grids of models covering the evolution of low mass stars (0.8 to 1.7Msun_) with metallicities Z=0.020 and 0.001 from the zero age main sequence up to the end of the early asymptotic giant branch are presented. The evolutionary tracks have been calculated with the new OPAL radiative opacities by Iglesias & Rogers (1993) and Kurucz (1991). They complete the base of extensive grids of stellar models computed by the Geneva Group with up-to-date input physics (Schaller et al. 1992; Schaerer et al. 1992; Charbonnel et al. 1993; Schaerer et al. 1993; Meynet et al. 1994).
