Résumé en anglais

We present a preliminary version of CPMDS, a new catalogue of Northern common proper motion visual double stars. All these stars are laying in the Bordeaux Carte du Ciel zone +11°<=δ<=+18°. We applied a statistical hypothesis t-test in the proper motions of the components. The proper motions used in our list were adopted from the Bordeaux proper motion catalogue PM2000. We detected 2831 new common proper motion double stars covering about 6% of the sky. This new catalogue is a large contribution to the small list of known common proper motion double stars.< Réduire
