FIRST ORBIT AND MASS DETERMINATIONS FOR NINE VISUAL BINARIES

摘要

This paper presents the first published orbits and masses for nine visual double stars: WDS?00149–3209 (B 1024), WDS?01006+4719 (MAD 1), WDS?03130+4417 (STT 51), WDS?04357+3944 (HU 1084), WDS?19083+2706 (HO 98 AB), WDS?19222–0735 (A 102 AB), WDS?20524+2008 (HO 144), WDS?21051+0757 (HDS 3004 AB), and WDS?22202+2931 (BU 1216). Masses were calculated from the updated Hipparcos parallax data when available and sufficiently precise, or from dynamical parallaxes otherwise. Other physical and orbital properties are also discussed.
