Scientific paper

Three homogeneous samples of late-type single- and double-lined main sequence spectroscopic binaries (a total of 56 systems) were analyzed by the maximum likelihood method. The distribution function of the masses of secondary components in each of the three samples exhibits two peaks at 0.1 and 0.5 solar mass and a gap at 0.2 solar mass. The bimodal character of the distribution disappears with orbital periods greater than about 150 d. At the lower end of the main sequence the frequency of spectroscopic binaries is less, and two-thirds of them have mass ratios greater than 0.5.
