Opacity tables for using in Paczynski stellar modelling and their effects on stellar evolutions
Öz
We have constructed opacity tables for using in stellar modelling in a format particularly applicable to the Paczynski freeware program GOB. Our tables are derived from those of Allard and Weiss for lower metal content envelopes, using the Lagrange interpolation method. This allows accurate opacities to be given as numerical functions of density and temperature with given proportions of hydrogen (X), helium (Y), and ‘metals’ (Z). Inlek et al. showed that it is possible independently to check opacity effects from modern high-quality observational data. These tables will be useful for such purposes.
