摘要：
A comparative investigation of the population of Galactic binary stars is performed for two modes of star formation: star formation at a constant rate over 10(10) yrs, and a burst of star formation that reprocesses the same mass of gas into stars over 10(9) yrs. Estimates are presented for the star-formation rates and populations of about 100 types of binaries and the products of their evolution. For most close binary systems, the models depend only weakly on the common-envelope parameter a,,. (C) 2002 MAIK "Nauka/Interperiodica".
