Abstract:
Continuing the effort to provide a homogeneous base of extensive and
accurate grids of stellar models covering a wide range of
metallicities we present a new grid of stellar models at metallicity Z
= 0.008, roughly corresponding to the Large Magellanic Cloud
composition. The models have been computed for 0.8 to 120 solar
masses, using up-to-date input physics and the new radiative opacities
from Rogers and Iglesias (1992ApJS...79..507R 1992ApJS...79..507R) and Kurucz (1991).
Mass loss and moderate core overshooting are taken into account. The
resulting HR diagram and the lifetimes in the H-, He-, and C-burning
phases as well as some general results on massive stars are discussed
and compared with complementary grids, using the same input physics at
metallicities Z of 0.020 and 0.001 used by Schaller et al. (1992, Cat.
