The analysis of the period distribution of eclipsing and spectroscopic binary systems shows the presence of some secondary maxima, which cannot depend on selection effects. These secondary maxima are mainly due to late type stars, as can be seen from the distribution curves for eclipsing binaries of various spectral types. The average separation of the components (in units of the sum of stellar radii) increases with the spectral type from O types to late B types, remaining almost constant for later spectral types.

Abstract
The analysis of the period distribution of eclipsing and spectroscopic binary systems shows the presence of some secondary maxima, which cannot depend on selection effects. These secondary maxima are mainly due to late type stars, as can be seen from the distribution curves for eclipsing binaries of various spectral types. The average separation of the components (in units of the sum of stellar radii) increases with the spectral type from O types to late B types, remaining almost constant for later spectral types.File in questo prodotto:
