Proper motion derivatives of binaries J/AJ/129/2420 ivo://CDS.VizieR/J/AJ/129/2420 doi:10.26093/cds/vizier.51292420 CDS Makarov V.V. Kaplan G.H. 2017-12-22T05:33:08Z 2005-06-06T22:30:19Z CDS support team CDS, Observatoire de Strasbourg, 11 rue de l'Universite, F-67000 Strasbourg, France cds-question@unistra.fr multiple-stars proper-motions visible-astronomy trigonometric-parallax Useful constraints on the orbits and mass ratios of astrometric binaries in the Hipparcos catalog are derived from the measured proper motion differences of Hipparcos and Tycho-2 ({Delta}{mu}), accelerations of proper motions (d{mu}/dt) and second derivatives of proper motions (d^2^{mu}/dt^2^). It is shown how, in some cases, statistical bounds can be estimated for the masses of the secondary components. Two catalogs of astrometric binaries are generated, one of binaries with significant proper motion differences and the other of binaries with significant accelerations of their proper motions. 2005AJ....129.2420M https://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/129/2420 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to I/239 : The Hipparcos and Tycho Catalogues (ESA 1997) https://cds.unistra.fr/vizier-org/licences_vizier.html https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/129/2420 https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/129/2420 http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/129/2420 https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/129/2420 https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/129/2420 http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/129/2420 GET text/xml+votable https://tapvizier.cds.unistra.fr/TAPVizieR/tap Cone search capability for table J/AJ/129/2420/table1 (A catalog of astrometric binaries with discrepant proper motions in Hipparcos and Tycho-2) https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/129/2420/table1? https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/129/2420/table1? http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/129/2420/table1?
