On the origin of the distribution of binary-star periods

Abstract

Pre-main sequence and main-sequence binary systems are observed to have periods, P , ranging from one day to 10 days and eccentricities, e, ranging from 0 to 1. We pose the problem if stellar-dynamical interactions in very young and compact star clusters may broaden an initially narrow period distribution to the observed width. N -body computations of… (More)
