cds-question@unistra.frmultiple-starsbrown-dwarfsexoplanetsWe present the latest results of an ongoing multiplicity survey of exoplanet hosts, which was initiated at the Astrophysical Institute and University Observatory Jena, using data from the second data release of the ESA-Gaia mission. In this study the multiplicity of 289 targets was investigated, all located within a distance of about 500pc from the Sun. In total, 41 binary, and five hierarchical triple star systems with exoplanets were detected in the course of this project, yielding a multiplicity rate of the exoplanet hosts of about 16%. A total of 61 companions (47 stars, a white dwarf, and 13 brown dwarfs) were detected around the targets, whose equidistance and common proper motion with the exoplanet hosts were proven with their precise Gaia DR2 astrometry, which also agrees with the gravitational stability of most of these systems. The detected companions exhibit masses from about 0.016 up to 1.66M_{sun}_ and projected separations in the range between about 52 and 9555au.2021FrASS.8.624907Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/FrASS/8.624907CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/345 : Gaia DR2 (Gaia Collaboration, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/FrASS/8.624907https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/FrASS/8.624907http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/FrASS/8.624907https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/FrASS/8.624907https://vizier.iucaa.in/viz-bin/votable?-source=J/other/FrASS/8.624907http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/FrASS/8.624907GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/FrASS/8.624907/table2 (Astrometry and photometry of planet hosts and companions)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/FrASS/8.624907/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/other/FrASS/8.624907/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/FrASS/8.624907/table2?GETtext/xml+votable180.050000true3.988845098994.251049733140.005555555555555556Cone search capability for table J/other/FrASS/8.624907/table4 (Equatorial coordinates and properties of companions)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/FrASS/8.624907/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/other/FrASS/8.624907/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/FrASS/8.624907/table4?GETtext/xml+votable180.050000true3.988584703554.252455247140.0055555555555555566/318 474 1040 1063 1075 3715 5207 5413 5614 5854 7264 7652 8235 11686 12935 19476 20381 20690 21076 21820 22773 26768 27332-27333 29852 30505 33116 33160 33212 34643 35786 35985 36197 36390 36759 36948 36956 37274 38381 39504 39807 41109 41179 41759 42714 42958 42980 44139 44143 44293 44311 44352 44378 44404 44436 45041 45108 45382 46333 46458 471681.9867573869263685e-19 3.916500758235022e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/FrASS/8.624907?format=asciidefaultJ/other/FrASS/8.624907/table2Astrometry and photometry of planet hosts and companionsSimbadNameSimbad column added by the CDSmeta.idcharNote2[SHC] SHC if AG is derived from Starhorse catalogmeta.notecharrecnoRecord number assigned by the VizieR team.
