Orbits and masses of twenty double stars discovered by Paul Couteau.

DOCOBO J.A. and LING J.F.

Abstract (from CDS):

In this article we present the orbits and masses of 20 double stars discovered by P. Couteau at the Nice Observatory (France), namely WDS 01450+2703 (COU 750), 03321+4340 (1688), 03423+3141 (691), 06503+2409 (768), 12409+2708 (596),14138+3059 (606), 15390+2545 (612), 16584+3943 (1289), 17075+3810 (1291), 17221+2310 (415), 18035+ 4032 (1785), 18043+4206 (1786), 19089+3404 (1462), 19180+2012 (321), 20151+3742 (2416), 20216+1930 (327 AB), 21593+4606 (2138), 22077+2622 (537), 22307+1758 (234) and 23199+2844 (439). For two of these stars, COU 750 and COU 1289, these are the first orbits to be published other than IAU Circulars; for the others, previously published orbits are improved on by those presented here. Star masses were in fifteen cases calculated from Hipparcos parallax data, and in the other five from dynamical parallaxes; in all cases, the error is estimated. Some of the other physical and orbital properties of these stars are also discussed.
