VizieR Online Data Catalog: Orbits of visual binaries and dynamical masses (Malkov+, 2012)

To compile the orbit list, we combined data from both OARMAC (catalog of Orbits and Ephemerides of Visual Double Stars) and ORB6 (Sixth Catalog of Orbits of Visual Binary Stars). At this stage, we maintained systems without parallax, but removed systems without a period / semi-major axis. The resulting list contains 3139 orbits for 2278 pairs: 1588 pairs have a single orbit, 548 pairs have two orbits, 120 pairs have three orbits, 19 pairs have four orbits, one pair has five orbits, and two pairs have seven orbits.

Table 1 contains a compiled set (1) of 3139 orbit solutions for visual binary stars. Separate entries are provided for different pairs in multiple systems. Several solutions per pair are possible. Each entry includes main orbital elements (Semi-major axis, period, eccentricity with corresponding uncertainties), indication of multiplicity and number of solutions, as well as visual magnitudes, spectral classes of the components, parallax and interstellar extinction estimate.

Table 2 contains a refined set of 652 solely binary systems with reliable orbit and determined parallax. One entry corresponds to one system. 3 masses estimates are provided: 1) Dynamical mass with uncertainty derived from Kepler's third law and trigonometric parallax, 2) Photometric mass estimated from visual magnitudes, parallax and mass-luminosity relation, 3) Spectroscopic mass based on mass-spectrum relation introduced by Straizys V. & Kuriliene G. 1981Ap&SS..80..353S.
