| Abstract: | We consider the time-scale of orbital circularization for those massive binary systems that produce WR+C systems. Using the observation that such systems have acquired circular orbits on a time-scale of the order of the Main-Sequence lifetime of the initial secondary, we estimate the intrinsic time-scale of the tidal interaction  0. We find that the tidal dissipation in such systems is very efficient and that, on the average, 0 ~ 103 yr. |
