Abstract

A statistical study of physical pairs from IDS catalogue has been performed. For 2811 binaries with luminosity class V primaries it has been found that their mass function is a Salpeter one; their distribution over semi-major axes of orbits is dN ∝ d log a. The rate of duplicity of stars is close to 1.
