Contact Binaries, Geometrical And Physical Parameters, Distribution

Scientific paper

The distributions of geometrical and physical parameters from the CCBS (Catalogue of Contact Binary Stars) and the ASAS-3 (The All Sky Automated Survey) are discussed. The distributions of orbital periods of light curves for 374 contact binaries from the CCBS as well as 3590 contact binaries, selected by Fourier decomposition of 4216 eclipsing binaries from the ASAS-3 database, are similar. The maxima of the period distributions are between 0.31 0.40 days (0.25 0.32 days for W-type and 0.35 0.40 days for A-type) and 0.40 0.45 days for the CCBS and ASAS-3 dataset, respectively.
