Stothers, R., 1973: The role of rotation in close binary systems of high mass. Publ. Astron. Soc. Pacific, 85, 363-378.
A quantitative confrontation of theory and observation of massive close binary systems is presented in order to evaluate the role of axial rotation in the evolution of the individual stellar components as well as the system as a whole. The detached systems are essentially unevolved, and possess components in approximately uniform rotation. The semidetached systems are definitely evolved, having suffered a heavy mass exchange before the stage of hydrogen exhaustion at the center of the original primary, and often possess mass-gaining components in fast nonuniform rotation. Except in the case of wide systems (P > 2 days), tidal friction eventually reintroduces synchronism of rotation in both components and both components evolve inhomogeneously. Spin-down times of the envelope and core, total rotational angular moments, and effects of spin-orbit interaction are calculated. A number of unexplained phenomena remain.
