The Tycho Catalogue contains reliable (BT , VT ) photometry for double star components with separations above a limit of about 3 arcsec. These data are used to investigate the distribution of mass ratios of main sequence binaries. For that purpose, two other points are treated rst: the correction of Tycho photometry for contamination by neighbour stars, and the derivation of the colour{magnitude diagram in the Tycho photometric system. It appears that the main sequence in the (VT abs, BT VT… CONTINUE READING
