Synchronization in the early-type detached binary stars.

PAN K.-K.

Abstract (from CDS):

With a set of homogeneous and refined rotational velocities, we discuss the synchronism in the "normal" (all the particular stars, such as Ap, Am and Of, are excluded) early-type detached binaries. Being different from previous statistical studies, the present paper not only investigates the rotational synchronism of each component, but also estimates its age from new stellar evolutionary grids, and calculates its synchronization time scale with Zahn's dynamically tidal theory. Significantly, we find that the dynamically tidal synchronization mechanism is substantially compatible with the observed data from the comparison of the rotational properties of our components with the theoretical predictions.
