Tables of evolutionary sequences for massive stars in the mass range 9 to 40 solar masses and mass ratios 0.9 and 0.6 are presented. The used code accounts for mass transfer according to case B (i.e., mass exchange after core hydrogen exhaustion) during semidetached and contact phases. The evolution of both components is followed simultaneously. All models are computed for a single initial chemical composition X = 0.7, Z = 0.02. Stellar wind mass losses are taken into account, as well as convective core overshooting (alpha = 0.25). The Roche lobe overflow is calculated according to a simplified hydrodynamical treatment, and accretion is approached assuming that infalling matter has the same specific entropy as the stellar surface layers. For the mixing of infalling material with the original layers, the process of thermohaline mixing is adopted. Moreover, it is assumed that 50 percent of the matter lost by the primary is accreted by the secondary. The models presented here may be used to interpret and evaluate the observations of Wolf-Rayet and massive X-ray binaries.
