TWO SCENARIOS OF MASS EXCHANGE IN CLOSE BINARY SYSTEMS CONSISTING OF THE LOW MASS PRE-MAIN SEQUENCE STARS

In this paper, we present the results of smoothed particle hydrodynamic (SPH) simulations of mass transfer in close binary systems consisting of the low mass pre-main sequence stars. Two scenarios of mass exchange in such systems are possible. If the more massive component is closer to fill its Roche lobe than the less massive, then the binary system merges as a result of the mass exchange. The binary system can survive only in the case if the less massive component is closer to fill its Roche lobe to the beginning of a mass exchange.
