Evolution of binary systems with repeated mass ejections

The effects of a series of isotropic ejections of small amounts of mass from either component of a binary system are studied. The evolution is completely different than in the case where all the mass is lost at once. When the ejections are randomly distributed in time, the final eccentricity may become larger or smaller than the initial one; the differences, however, are in most cases small. When the frequency of the explosions is higher near periastron, the final eccentricity is in most cases larger than the original value. In almost no case the system is disrupted.
