The observational data on 58 pre-main sequence (PMS) double-lined spectroscopic binaries (SB2) and 115 stars with protoplanetary disks are compiled for statistical investigation. These stars are located in different star-forming regions. The constructed distributions of young stars by component masses, taking into account the effects of observational selection (discovery probability and/or occupied volume), are approximated with a power law
stars: pre-main sequence, binaries: spectroscopic, mass function; methods: statistical
