A photometric study of wide visual double stars. IV - UVBY photometry of wide visual double stars with G-type primaries
We performed uvby aperture photometry of wide visual double stars withG-type primaries. The minimum angular separation of the components is 10arcsecs and mainly less than 20 arcsecs. As both components have oftensimilar photometric and astrophysical parameters, we infer that most ofthese double stars have components of common origin.
