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 astrometric and photometric data from the ESA-Gaia mission to detect stellar companions of these stars and characterize their properties. A total of 134 binary, 6 hierarchical triple, and 2 quadruple star systems are identified among 1106 targets whose multiplicity is investigated in the course of our survey, located at distances closer than about 500pc around the Sun. The detected companions and targets are at the same distance and have a common proper motion, as expected for components of gravitationally bound stellar systems, as demonstrated by their accurate Gaia DR3 astrometry. The companions have masses from about 0.11 to 2M_{sun}_ and are most abundant in the mass range between 0.2 and 0.5M_{sun}_. The companions have projected separations from the targets between about 50 and 9700au. Their frequency is the highest and constant from about 300 up to 750au, decreasing at larger projected separations. In addition to main sequence stars, four white dwarf companions are detected in this study, whose true nature is revealed by their photometric properties.2023AN....34430055Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AN/344/55CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/490/5088 : Stellar companions of exoplanet host stars (Mugrauer, 2019)J/AN/341/996 : Stellar companions of (C)TOIs (Mugrauer+, 2020)J/AN/342/840 : Stellar companions of (C)TOIs (Mugrauer+, 2021)J/AN/343/24017 : Stellar companions of (C)TOIs (Mugrauer+, 2022)J/other/FrASS/8.624907 : (Sub)Stellar companions of exoplanet hostshttps://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/344/55https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AN/344/55http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AN/344/55https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AN/344/55https://vizier.iucaa.in/viz-bin/votable?-source=J/AN/344/55http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AN/344/55GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AN/344/55/table3 (Equatorial coordinates and properties of companions)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AN/344/55/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AN/344/55/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AN/344/55/table3?GETtext/xml+votable180.050000true52.67980914211-22.005741004480.0055555555555555566/445 832 1020 1271 1307 1508 1826 1841 2250 2687 2996 3070 3227 3499 3646 3682 3729 3848 3853 4040 4974 5193 6877 6932 6943 6953 7347 7582 7992 8029 8139 8864 9179 9206 9632 9644 9889 9919 10109 10879 10979 11182 11253 11338 11519 11775 11972 13033 14266 14292 14308 14458 14613 14627 14753 14944 15199 15420 15474 15493 15584 16100 16126 16186 16588 16905 16989 17262 17614 18225 19959 20701 21427 22257 22660 24551 24666 24951 25611-25612 28704 28714 28768 32148 32544 32948 33014 33236 33840 34209 35243 36229 36248 36965 37039 37172 37267 37324 37607 37834 37934 37995 38050 38192 38273 38400 38963 39199 39233 39359 39704 39889 39892 39949 40799 41160 41274 41435 41640 41696 41708 41838 42054 42100 42525 42826 43270 43499 43861 43925 43928 44161 44565 44677 45088 47122 47205 47231 47384 47502 47767https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AN/344/55?format=asciiOpticaldefaultJ/AN/344/55/table1Astro- and photometry of (C)TOIs and companionsrecnoRecord number assigned by the VizieR team.
