cds-question@unistra.frmultiple-starsorbitsinterferometryThe orbits of 55 visual binary stars are computed using recent speckle interferometry data from the SOAR telescope: 33 first-time orbits and 22 revisions of previous orbit calculations. The orbital periods range from 1.4-370 years, and the quality of the orbits ranges from definitive to preliminary and tentative. Most binaries consist of low-mass dwarfs and have short periods (median period 31 years). The dynamical parallaxes and masses are evaluated and compared to the Hipparcos parallaxes. Using differential speckle photometry, binary components are placed on the color-magnitude diagram.2016AJ....152..138Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/152/138CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/wds : The Washington Visual Double Star Catalog (Mason+ 2001-2014)I/311 : Hipparcos, the New Reduction (van Leeuwen, 2007)I/239 : The Hipparcos and Tycho Catalogues (ESA 1997)V/39 : 4th Catalog of Orbits of Visual Binaries (Worley+, 1983)J/AJ/150/151 : DSSI observations of binaries.
