Statistical regularities of spectral characteristics of the components of visual binaries.
Abstract
Spectral distributions and some statistical relations among the brightness differences and composite spectra of 394 components of 197 visual binaries are analyzed. The spectral distribution of binaries with two main-sequence components is determined, and properties of the composite spectra of these systems are examined. Statistical relations between the components of systems containing at least one post-main-sequence component are discussed.
