cds-question@unistra.frmultiple-starsproper-motionsvisible-astronomytrigonometric-parallaxstellar-massesWe present the latest results of our ongoing multiplicity study of (Community) TESS Objects of Interest, using astro- and photometric data from the ESA-Gaia mission, to detect stellar companions of these stars and to characterize their properties. In total, 107 binary, 5 hierarchical triple star systems, as well as one quadruple system were detected among 585 targets surveyed, which are all located at distances closer than about 500pc around the Sun. As proven with their accurate Gaia EDR3 astrometry, the companions and the targets are located at the same distance and share a common proper motion, as it is expected for components of gravitationally bound stellar systems. The companions exhibit masses in the range between about 0.09M_{sun}_ and 4.5M_{sun}_ and are most frequently found in the mass range between 0.15 and 0.6M_{sun}_. The companions are separated from the targets by about 120 up to 9500au and their frequency is the highest and constant within about 500au while it continually decreases for larger separations. Beside mainly early to mid M dwarfs, also 5 white dwarf companions were identified in this survey, whose true nature was revealed by their photometric properties.2021AN....342..840Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AN/342/840CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/490/5088 : Stellar companions of exoplanet host starsJ/AN/341/996 : Stellar companions of (C)TOIs (Mugrauer+, 2020)J/other/FrASS/8.624907 : (Sub)Stellar companions of exoplanet hostshttps://www.astro.uni-jena.de/Users/markus/Multiplicity_of_(C)TOIs.htmlhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AN/342/840https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AN/342/840http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AN/342/840https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AN/342/840https://vizier.iucaa.in/viz-bin/votable?-source=J/AN/342/840http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AN/342/840GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AN/342/840/table3 (Equatorial coordinates and properties of companions)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AN/342/840/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AN/342/840/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AN/342/840/table3?GETtext/xml+votable180.050000true116.37063898358-52.382569046570.0055555555555555566/1213 2954 3004 3717 3731 3994 4163 4579 5547 7600 7670 7888 8675 9219 9318 9480 9482 9555 9580 9618 9660 10678 10700 11238 11573 11719 11739 12239 14291 14878 14951 14973 15143 15609 15780 15979 16108 16222 16306 16660 16808 17344 17605 17832 18009 19836 20869 21045 21820 22554 23555 24769 25122 27971 31727 32225 32550 32801 32826 33001 33096 33172 33393 33612 33973 34113 34332 34423 34480 34516 35157 35192 36640 36978 37230 37391 37514 37556 37568 37592 37595 37764 37910 38203 38282 39006 39054 39179 39428 39580 39599 42614 43017 43163 43361 43368 43410 43696 43778 43916 44552 44561 45285 45638 46015 46527 46718 47015 47469 47947 48009 48175 48521https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AN/342/840?format=asciiOpticaldefaultJ/AN/342/840/table1Astro- and Photometry of (C)TOIs & CompanionsrecnoRecord number assigned by the VizieR team.
