A Bayesian search for binaries in Hipparcos J/ApJS/192/2 ivo://CDS.VizieR/J/ApJS/192/2 doi:10.26093/cds/vizier.21920002 CDS Shaya E.J. Olling R.P. 2023-07-21T13:40:57Z 2011-04-11T19:26:34Z CDS support team CDS, Observatoire de Strasbourg, 11 rue de l'Universite, F-67000 Strasbourg, France cds-question@unistra.fr multiple-stars proper-motions radial-velocity We develop Bayesian statistical methods for discovering and assigning probabilities to non-random (e.g., physical) stellar companions. These companions are either presently bound or were previously bound. The probabilities depend on similarities in corrected proper motion parallel and perpendicular to the brighter component's motion, parallax, and the local phase-space density of field stars. Control experiments are conducted to understand the behavior of false positives. The technique is applied to the Hipparcos Catalogue (Cat. I/239) within 100pc. This is the first all-sky survey to locate escaped companions still drifting along with each other. In the <100pc distance range, ~220 high probability companions with separations between 0.01 and 1pc are found. The first evidence for a population (~300) of companions separated by 1-8pc is found. 2011ApJS..192....2S https://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/192/2 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to I/239 : The Hipparcos and Tycho Catalogues (ESA 1997) I/311 : Hipparcos, the New Reduction (van Leeuwen, 2007) I/259 : The Tycho-2 Catalogue (Hog+ 2000) https://cds.unistra.fr/vizier-org/licences_vizier.html https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/192/2 https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/192/2 http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/192/2 https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/192/2 https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/192/2 http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/192/2 GET text/xml+votable https://tapvizier.cds.unistra.fr/TAPVizieR/tap Cone search capability for table J/ApJS/192/2/catalog (Candidate companions for candidate primaries within 25pc (table3; Seq 1-111) between 25 and 50pc (table4; Seq 112-376) or between 50 and 100pc (table5 of the paper; Seq 377-840)) https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/192/2/catalog? https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/192/2/catalog? http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/192/2/catalog?
