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.
| CCD measurements of visual binaries
CCD measurements of visual double stars were obtained with the ESO 1.5 mdanish reflector. All binaries observed are candidates for the HIPPARCOSInput Catalogue. More than 400 observations have been made in four clearnights. The accuracy obtained is comparable to the accuracy of thephotographic technique, but the observing and reduction times are oneorder of magnitude smaller.
