J/A+AS/133/123 Stellar models until He burning - IV. (Claret+ 1998) ================================================================================ Stellar models for a wide range of initial chemical compositions until helium burning IV. From X=0.65 to X=0.80 for Z=0.004 Claret A., Gimenez A. =1998A&AS..133..123C (SIMBAD/NED BibCode) ================================================================================ ADC_Keywords: Models, evolutionary Keywords: binaries: eclipsing - stars: evolution; interiors; fundamental parameters - Magellanic Clouds 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.
