Abstract:
Double-lined, detached eclipsing binaries are our main source for
accurate stellar masses and radii. In this paper we focus on the
1.15-1.70M☉ interval where convective core overshoot is
gradually ramped up in theoretical evolutionary models. We aim to
determine absolute dimensions and abundances for the F-type detached
eclipsing binary BK Peg, and to perform a detailed comparison with
results from recent stellar evolutionary models, including a sample of
previously studied systems with accurate parameters.
