Orbits, masses and dynamical parallaxes of 12 visual binary systems

Abstract

In this paper the preliminary orbital elements are presented for the following double stars: WDS 00153+4412 = A 1256 AB, WDS 00470+2315 = HU 413, WDS 00520+3154 = A 924, WDS 01036+6341 = MLR 87, WDS 01131+2942 = A 1260, WDS 01158+0947 = A 2102, WDS 01200-1549 = HJ 2036, WDS 02423+4925 = HU 539, WDS 02512+0141 = A 2338, WDS 02514-2139 = DON 43, WDS 06253+0130 = FIN 343, WDS 20329+1142 = J 1. For all pairs in addition to the orbital elements, the dynamical parallaxes, the masses, the absolute magnitudes, the observations the residuals (O-C) and the ephemerides for the next six years are given.
