J/A+AS/103/67     Evolutionary sequences with MC metallicities  (de Loore+ 1994)

Evolutionary sequences for massive close binary stars with Magellanic Cloud metallicities with Rogers-Iglesias opacities de Loore C., Vanbeveren D. <Astron. Astrophys. Suppl. Ser. 103, 67 (1994)> =1994A&AS..103...67D

The orbital periods are chosen such that mass transfer according to case B occurs, i.e. mass exchange after core hydrogen exhaustion, during semi-detached and contact phases. The evolutionary code used by de Loore & De Greve (1992A&AS...94..453D) for galactic massive close binaries was updated, i.e. new thermodynamic quantities and new opacities were installed. The evolution of both components is followed simultaneously. Stellar wind mass loss rates during the OB phase are scaled according to the radiatively driven wind theory. Wolf-Rayet mass loss rates are assumed to be independent of metallicity. The models presented here may be used to interpret and evaluate the observations of Wolf-Rayet stars and massive binary X-ray sources in the Small and Large Magellanic Clouds. File Summary:

Note (1): The different phases is as follows: ZAMS: Zero Age Main Sequence RP1: Red Point of the primary component Xc1=0: end of core hydrogen burning of the primary RLOFi: onset of a case B of Roche Lobe Overflow Lmin: minimum luminosity of the primary Xat<0.76 (SMC, or 0.74 (LMC)): hydrogen abundance of the primary drops below its initial value CHeB1i: onset of core helium burning of the primary VHeB1i: onset of core helium burning of the primary RLOFf: end of Roche Lobe Overflow Yc1=0: end of core helium burning of the primary RP2: red point of the secondary Xc2=0: end core hydrogen burning of the secondary. Teffmin2: minimum of the effective temperature of the secondary Teffmax2: maximum of the effective temperature of the secondary WNL1,WNE1, WC1 denote the onset of the different Wolf-Rayet phases, the WNL,WNE and WC-phases of the primary.
