Abstract:
As a continuation of previous papers in a series devoted to the
computation of stellar structure and evolution models we present a
grid specifically obtained for detailed studies of the stellar content
of the Small Magellanic Cloud. The initial metal content has thus been
adopted to be Z=0.004 while the hydrogen content varies from 0.65 to
0.80 leaving as an intermediate value that given by standard laws of
enrichment, X=0.744. Interpolation for different environment is
therefore possible with these new models. Other input physics
parameters, e.g. convective overshooting, mixing-length, opacities or
nuclear reaction rates, have been adopted to be homogeneous with the
previously published models in order to facilitate comparative
studies.
