Abstract

Extending our previous study, the present paper reports on the discussion of the orbital circularization in 37 detached binaries with early-type primaries. From comparison of the theoretical predictions with the orbital eccentricities of our binary systems, we find that Zahn's circularization theories are substantially consistent with the observed data for overwhelming majority of our samples. However, we also note that three binaries of whom both components are asynchronized rotators possess circular orbits. How to understand the circularism of the three systems remains a problem not only to Zahn's theories, but to all other present circularization mechanisms.We think that studies on the circularization of pre-main-sequence binary systems could provide some clues for the problem.
