Interacting binary stars
Internal structure coefficients for zero age Main Sequence (ZAMS) model stars with different initial metallicities are presented. A series of (Eggleton) stellar models with masses between 1 – 40 M ⊙ $1\mbox{--}40\,M_{\odot}$ and metallicities Z = 0.0001 $Z=0.0001$ , Z = 0.001 $Z=0.001$ , Z = 0.004 $Z=0.004$ , Z = 0.01 $Z=0.01$ , Z = 0.02 $Z=0.02$ , and Z = 0.03 $Z=0.03$ were used. We have also calculated the same coefficients for a recommended solar metallicity value Z = 0.0134 $Z=0.0134$ (Asplund et al. in Annu. Rev. Astron. Astrophys. 47:481, 2009). For each model, values of the internal structure constants k 2 $k_{2}$ , k 3 $k_{3}$ , k 4 $k_{4}$ and related coefficients have been derived by numerically integrating Radau’s equation with the (FORTRAN) program RADAU. The (Eggleton) stellar models used come from the ‘EZ-Web’ compilation of the Dept. of Astronomy, University of Wisconsin, Madison. The calculations follow the procedure given by Inlek and Budding (Astrophys. Space Sci. 342:365, 2012). These new results were compared with others in the literature.
