Abstract:
We use estimates of ages and abundances made for a set of eclipsing
binaries (Kovaleva, 2001, Cat. <J/AZh/78/1104), to re-calculate
observational values of radii, effective temperatures and luminosities
of these stars for solar abundance ZAMS. Geneva group evolutionary
grids of models were used for this recalculation. We also present
empirical and semi-empirical (for ZAMS evolutionary stage and solar
metallicity) relations between mass and luminosity, temperature and
radius.
