Supernovae in binary systems.
Abstract
The general problem of a supernova explosion in a binary star system is studied. We show that to a good approximation the effect of the impinging blast wave which strips and ablates mass from the companion can be expressed in terms of a single parameter. The eccentricity imparted to the system and the ratio of final to initial semi-major axes depend on two to six parameters, depending on the level of approximation. Results for calculation of the eccentricity imparted to an initially circular system are presented by means of graphs, tables, and sample fitting formulae for two basic types of models: one in which the companion is a 'normal' star and one in which the companion is in a 'red-giant' phase. We conclude that neutron stars can be formed in close binary systems but that the resulting orbit must have a finite eccentricity.
