Test of Convective Core Overshooting Using Evolved Eclipsing Binaries.
Double-lined eclipsing binaries are known to be the source of accurate stellar dimensions. Masses of radii of the component stars can be obtained with uncertainties around 1-2%, thus leading to the much-needed test of current models for stellar structure and evolution. In the present communication we focus on the comparison of observational data and model predictions for a sample of evolved eclipsing binaries, i.e. with components close to or beyond the TAMS, with the aim of studying the significance of convective core overshoot.
