Recent Results on the Apsidal Motion Test in Eclipsing Binaries
Published online by Cambridge University Press: 07 August 2017
Abstract
A selected sample of eclipsing binaries with well-defined apsidal motion rates and accurate absolute dimensions has been analysed and compared with most recent evolutionary models of the stellar internal structure. A reasonably good agreement has been achieved when models including convective-core overshooting, mass loss, and stellar rotation in the evolutionary code, are used. The systematic difference in log k2 reported by previous authors between observed and theoretically predicted values is no longer detected for stars with well-determined absolute dimensions, and a few anomalous cases can be easily explained in terms of the validity of the adopted assumptions.
