cds-question@unistra.frmultiple-starsproper-motionsvisible-astronomytrigonometric-parallaxstellar-massesThe first results of a new survey are reported, which explores the 2nd data release of the ESA-Gaia mission, in order to search for stellar companions of (Community) TESS Objects of Interest and to characterize their properties. In total, 193 binary and 15 hierarchical triple star systems are presented, detected among 1391 target stars, which are located at distances closer than about 500pc around the Sun. The companions and the targets are equidistant and share a common proper motion, as it is expected for gravitationally bound stellar systems, proven with their accurate Gaia astrometry. The companions exhibit masses in the range between about 0.08M_{sun}_ and 3M_{sun}_ and are most frequently found in the mass range between 0.13 and 0.6M_{sun}_. The companions are separated from the targets by about 40 up to 9900au, and their frequency continually decreases with increasing separation. While most of the detected companions are late K to mid M dwarfs, also 5 white dwarf companions were identified in this survey, whose true nature is revealed by their photometric properties.2020AN....341..996Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AN/341/996CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/490/5088 : Stellar companions of exoplanet host stars (Mugrauer, 2019)https://www.astro.uni-jena.de/Users/markus/Multiplicity_of_(C)TOIs.html :https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AN/341/996https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AN/341/996http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AN/341/996https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AN/341/996https://vizier.iucaa.in/viz-bin/votable?-source=J/AN/341/996http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AN/341/996GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AN/341/996/table1 (Astro- & Photometry of (C)TOIs & Companions)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AN/341/996/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AN/341/996/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AN/341/996/table1?GETtext/xml+votable180.050000true79.5209381356-80.964383992720.005555555555555556Cone search capability for table J/AN/341/996/table3 (Equatorial Coordinates & Properties of Companions)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AN/341/996/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AN/341/996/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AN/341/996/table3?GETtext/xml+votable180.050000true79.52265766889-80.96493231970.0055555555555555566/508 1585 2403 2970 2999 3294 3475 3753 3934 5186 5326 5702 5755 6059 6240 6583 6978 6997 7161 7241 7383 7689 7838 7934 7973 8179 8864 9960 10089 10182 10223 10231 10476 11029 11510 11542 11590 11598 11602 11612 11672 11724 11763 11770 11905 12924 13750 13770 13892 13916 14054 14178 14241 14317 14381 14576 14847 14878 15101 15182 15226 15252 15254 15281 15316 15376 15438 15504 15732 15748 15817 15868 15911 15915 16003-16004 16012 16014 16020 16037 16052-16053 16055 16092 16238 16300-16301 16318 16632 16722 17240 20460 20538 20692 20758 21176 21197 21206 21271 21346 21766 21986 22662 23007 24557 25193 27985 28071 30705 32811 32813 32838 32858 32912-32913 32940 33000 33073 33110 33159 33164 33207 33224 33279 33299 33321 33477 33598 33702 33818 33840 33849 33854 33903 33959 34423 34468 34784 34843 34986 35018 35210 35240 35406 35439 35841 35914 36112 36643 36972 37014 37067 37284 37303 37309 37313 37361 37435 37497 37690 37809 37938 38101 38143 38386 38480 38615 38743 39006 39013 39036 39084 39139 39349 39422 39463 39569 39646 40189 40315 40425 40456 40545 40571 40673 40754 40968 41995 42895 43437 43551 44046 45163 45165 45172 45453 45499 45925 46093 46111 46151 46771 46866 47133 47327 48169 48457https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AN/341/996?format=asciiOpticaldefaultJ/AN/341/996/table1Astro- & Photometry of (C)TOIs & CompanionsRA_ICRSRight Ascension (ICRS) at Ep=2015.5degpos.eq.ra;meta.mainrecnoRecord number assigned by the VizieR team.
