cds-question@unistra.frmultiple-starsorbitsinterferometryOrbits of 44 close and fast visual binaries are computed using the latest speckle observations; 23 orbits are determined for the first time, and the rest are revisions, some of those substantial. Six combined orbits use radial velocities. The median period is 15.6 years, and the shortest period is one year. Most stars are nearby late-type dwarfs. Dynamical parallaxes and estimates of the masses are derived from the orbital elements and the photometry of the components.2017AJ....154..110Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/154/110CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/wds : The Washington Visual Double Star Catalog (Mason+ 2001-2014)V/130 : Geneva-Copenhagen Survey of Solar neighbourhood III (Holmberg+, 2009)I/311 : Hipparcos, the New Reduction (van Leeuwen, 2007)J/AJ/152/138 : Orbits based on SOAR speckle interferometry (Tokovinin, 2016)J/ApJ/799/4 : Robo-AO observations of binary stars (Riddle+, 2015)J/AJ/150/50 : Speckle interferometry at SOAR in 2014 (Tokovinin+, 2015)J/AJ/147/123 : Speckle interferometry with SOAR in 2012-13 (Tokovinin+, 2014)J/AJ/144/56 : Speckle interferometry at SOAR in 2012 (Tokovinin+, 2012)J/AJ/143/42 : Speckle interferometry at SOAR in 2010 & 2011 (Hartkopf+, 2012)J/ApJ/734/70 : Chromospheric activity of Southern stars (Arriagada, 2011)J/AJ/139/743 : Speckle interferometry in 2008-09 (Tokovinin+, 2010)J/ApJ/521/682 : Binaries in the Praesepe and Coma clusters (Abt+, 1999)J/A+AS/123/93 : Lambda Boo stars consolidated catalogue (Paunzen+ 1997)J/AJ/106/773 : Mass-luminosity relation (Henry+, 1993)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/154/110https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/154/110http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/154/110https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/154/110https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/154/110http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/154/110GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/154/110/binaries (Orbital elements (table1), and parallaxes and photometry (table3))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/154/110/binaries?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/154/110/binaries?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/154/110/binaries?GETtext/xml+votable180.050000true3.37115-36.8287050.0055555555555555566/359 4670 4698 6146 16401 18508 19569 20841 21149 21498 22762 22792 23312 25037 25206 25267 27204 27596 29784 31748 32257 33224 33411 33582 34517 35063 35088 39256 39676 40769 41655 42109 42328 43364 44447 44865 45551 45918 46010 46998 47254 47529 48212 48345https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/154/110?format=asciidefaultJ/AJ/154/110/binariesOrbital elements (table1), and parallaxes and photometry (table3)recnoRecord number assigned by the VizieR team.
