Abstract

We report the identification of new wide common proper motion pairs extracted from the LSPM-North Catalogue. Objects with proper motion differences from 5% to 10% and separations from four seconds of arc up to approximately twelve arc minutes have been included in our list. The primary star of one of the pairs we have detected has a measured parallax of 106+/-55 mas, while for another 12 of them the parallaxes are from 10 to 38 mas (with errors in the range +/-0.7 mas to +/-2.3 mas). If these 13 systems are physically connected and the secondaries are located at distances similar to the primaries, then the total population of stars within 100 pc of the Sun may have 13 new members.
