Özet:

 

The orbital angular momentum (orbital AM) of a sample of  forty RS CVn-type binaries with the orbital periods P \leq 10 days  were estimated and the orbital AM distribution with respect to P was  critically interpreted as the orbital AM evolution of these systems  caused by the magnetic breaking process with the existence of  spin-orbit coupling.  The empirical relations (between the orbital AM  loss, mass loss and period variation) derived from the diagram of the  orbital AM distribution were used in deriving a semi-empirical formula  for the dynamical evolution of the RS CVn-type binaries.  The magnetic breaking induced dynamical evolution of the RS CVn-type  binaries maybe at different rates but is always towards the shorter  periods in the existence of spin-orbit coupling and before the Roche lobe filling of a component star.
