The CPMDS catalogue of common proper motion double stars in the Bordeaux Carte du Ciel zone.


Abstract (from CDS):

The present knowledge of common proper motion double stars is rather poor and almost entirely restricted to the Luyten LDS catalogue of 6210 pairs, to 439 pairs of Halbwachs catalogue of common proper motion stars in AGK3, and to Greaves new northern common proper motion pairs (975 pairs). We present a search for new double stars with common proper motion in the Bordeaux, PM2000, proper motion catalogue (+11°≤δ≤+18°). The selection of double stars, on the basis of common proper motion, was performed by testing the candidate pairs with a Student t-distribution hypothesis test. A classification was performed by the analysis of the photometric properties of the components. We present a catalogue, which contains 2572 new common proper motion pairs with angular separations ρ≤2 ' and PM2000 meridian magnitudes for both components. As a by-product, we present the remeasurement of the parameters of 926 visual pairs from the WDS Washington double star catalogue. The present catalogue, which is a list of candidate binaries, is an important step in the knowledge of double stars because it increases the number of known common proper motion pairs by 30%.
