On the Modeling of Algol-Type Binaries

In earlier papers, we presented a binary evolutionary code for the purpose of reproducing orbital parameters, masses, radii, and location in Hertzsprung Russell diagram (abbreviated as HRD) well-observed Algol systems. subsequent versions, effects mass angular momentum losses tidal coupling were included order to produce observed distributions periods ratios Algol-type binaries. The loss includes stellar wind possible liberal evolution, when gainer star is not capable absorb all matter during transfer from donor star. We added magnetic braking our better reproduce equatorial velocities. Large velocities mass-gaining stars are now lowered by interaction braking. Tides mainly at work short periods, leaving alone longer periods. values gainers binaries mostly well reproduced code. According models, Algols have with strong field.
