  ABSTRACT: In this paper, the orbital elements for 11 visual binaries are given and calculated. Eight already possess orbits, but here they are recalculated. The reason is that recent measurements show higher residuals with respect to the corresponding ephemerides calculated by using the orbital elements given in the Sixth Catalog of Orbits of Visual Binary Stars. The eight binaries are: WDS 03454−2752, WDS 03596−1019, WDS 04400+5328, WDS 05322+7049, WDS 06274−2544, WDS 08254+3723, WDS 17457+1743 and WDS 19531−1436. For three binaries the orbital elements are calculated for the first time: WDS 00046+4206, WDS 04496−5353 and WDS 17141−0824. In addition to the orbital elements in this paper masses, dynamical parallaxes, absolute magnitudes and ephemerides for the next five years are also given and calculated.

  ABSTRACT: In this paper orbits for 13 binaries are recalculated and presented. The reason is that recent observations show higher residuals than the corresponding ephemerides calculated by using the orbital elements given in the Sixth Catalog of Orbits of Visual Binary Stars. The binaries studied were: WDS 00182+7257 = A 803, WDS 00335+4006 = HO 3, WDS 00583+2124 = BU 302, WDS 01011+6022 = A 926, WDS 01014+1155 = BU 867, WDS 01112+4113 = A 655, WDS 01361-2954 + HJ 3447, WDS 02333+5219 = STT 42 AB, WDS 04362+0814 = A 1840 AB, WDS 08017-0836 = A 1580, WDS 08277-0425 = A 550, WDS 17471+1742 = STF 2215 and WDS 18025+4414 = BU 1127 Aa-B. In addition, for three binaries - WDS 01532+1526 = BU 260, WDS 02563+7253 =STF 312 AB and WDS 05003+3924 = STT 92 AB - the orbital elements are calculated for the first time. In this paper the authors present not only the orbital elements, but the masses, dynamical parallaxes, absolute magnitudes and ephemerides for the next five years, as well.
