The Period Distribution of Eclipsing and Spectroscopic Binary Systems  Part Two
Abstract
A statistical analysis of period distribution for eclipsing and spectroscopic binary systems, based on the spectral types of the components, shows several common features between the two independent samples. The similarity is increased if we eliminate the geometrical selection effect on the eclipsing binaries sample by means of the method described in previous papers. The period distribution becomes broader (and probably nonunimodal) for advanced spectral types. We also performed an analysis of the mean separation of systems as a function of the spectral type.
