The Visual Double Stars in the Bordeaux PM2000 Astrometric Catalogue

Authors
Abstract:
We present astrometric characteristics of about 1250 wide visual double stars. They are all binaries contained in the data base of the Washington Double Star Catalogue (WDS), which could be found in the 2.400.000 stars of the Bordeaux PM2000 astrometric catalogue. They sum up to 1.2% of all entries of the last version (2006) of WDS. Minimum angular separation of the pairs is 8 arcseconds. The faintest secondary found is a 15th magnitude star. Although they are very wide double stars, about 30% of them are statistically common proper motion pairs and thus, their components are consequently common origin stars.
