cds-question@unistra.frmultiple-starsorbitsOrbital elements of 18 visual binaries are computed using the measurements collected in the Fourth Catalog of Interferometric Measurements of Binary Stars; 15 orbits are determined for the first time and three orbits are revised. Eleven of the binaries, denoted as HDS, were discovered during the Hipparcos mission. The remaining binaries were discovered a few years earlier or later than 1991. All studied pairs are close, and all measured separations are less than 0.46". The shortest orbital period is 10 years and the longest orbital period is 127 years. Dynamical parallaxes and total masses of systems are derived from the orbital elements. We also give absolute magnitudes, spectral types, and (O-C) residuals in {theta} and {rho}.2017AJ....154..273Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/154/273CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/135 : Henry Draper Catalogue and Extension (Cannon+ 1918-1924; ADC 1989)V/39 : 4th Catalog of Orbits of Visual Binaries (Worley+, 1983)I/239 : The Hipparcos and Tycho Catalogues (ESA 1997)I/311 : Hipparcos, the New Reduction (van Leeuwen, 2007)J/AJ/111/370 : Orbits of 37 close visual systems (Hartkopf+ 1996)J/A+A/341/121 : Visual binary orbits and masses (Soederhjelm 1999)J/AJ/123/1023 : Binary star orbits (Seymour+, 2002)J/A+A/546/A69 : Orbits of visual binaries and dynamical masses (Malkov+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/154/273https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/154/273http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/154/273https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/154/273https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/154/273http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/154/273GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/154/273/stars (Stars positions (from Simbad))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/154/273/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/154/273/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/154/273/stars?GETtext/xml+votable180.050000true1.533477291666679.7149364166666740.0055555555555555566/419 1181 1318 6720 9834 12701 12889 16823 17713 19563 23271 23519 42076 46681https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/154/273?format=asciidefaultJ/AJ/154/273/table3Observational data and residualsrecnoRecord number assigned by the VizieR team.
