A statistical analysis of the 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 the geometrical selection effect on the eclipsing binary sample is eliminated by means of the method described in previous papers. The period distribution becomes broader (and probably nonunimodal) for advanced spectral types. Analysis of the mean separation of systems as a function of the spectral type was also performed.

Abstract
A statistical analysis of the 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 the geometrical selection effect on the eclipsing binary sample is eliminated by means of the method described in previous papers. The period distribution becomes broader (and probably nonunimodal) for advanced spectral types. Analysis of the mean separation of systems as a function of the spectral type was also performed.File in questo prodotto:
