cds-question@unistra.frmultiple-starsproper-motionsvisible-astronomytrigonometric-parallaxstellar-massesIn this paper we present the latest results of our ongoing multiplicity survey of (Community) TESS Objects of Interest, using astrometry and photometry from the latest data release of the ESA Gaia mission to detect stellar companions of these stars and to characterize their properties. A total of 92 binary and two hierarchical triple star systems are identified among the 745 target stars whose multiplicity is explored in this study, all at distances of less than 500pc around the Sun. As expected for components of gravitationally bound star systems, the targets and the detected companions are at the same distance and share a common proper motion, as shown by their accurate Gaia astrometry. The companions have masses of about 0.12 to 1.6M_{sun}_ and are most frequently found in the mass range up to 0.6M_{sun}_. The companions have projected separations from the targets between about 110 and 9600au. Their frequency is highest and constant from about 300 to 800au, decreasing at larger projected separations. In addition to main sequence stars, five white dwarf companions are detected in this study, whose true nature is unveiled by their photometric properties.2025AN....34670005Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AN/346/70005CatalogResearchIsServedByTAP 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/other/FrASS/8.624907 : (Sub)Stellar companions of exoplanet hostsJ/AN/342/840 : Stellar companions of (C)TOIs (Mugrauer+, 2021)J/AN/343/24017 : Stellar companions of (C)TOIs (Mugrauer+, 2022)J/AN/344/55 : Stellar companions of (C)TOIs (Mugrauer+, 2023)J/MNRAS/527/3183 : (Sub)Stellar companions of exoplanet hosts (Michel+, 2024)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/346/70005https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AN/346/70005http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AN/346/70005https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AN/346/70005https://vizier.iucaa.in/viz-bin/votable?-source=J/AN/346/70005http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AN/346/70005GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AN/346/70005/table1 (Astrometry and Photometry of (C)TOIs & Companions)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AN/346/70005/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AN/346/70005/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AN/346/70005/table1?GETtext/xml+votable180.050000true242.415076465.82798470.005555555555555556Cone search capability for table J/AN/346/70005/table3 (Equatorial Coordinates and Properties of Companions)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AN/346/70005/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AN/346/70005/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AN/346/70005/table3?GETtext/xml+votable180.050000true242.425717062265.821262843630.0055555555555555566/119 222 396 542 622 723 728 768 1144 1513 1676 3705 4179 4268 4303 4659 4953 5129 5173 5216 5436 5472 6446 6580 7033 7075 7216 7788 8043 8797 9789 10164 10420 11559 11667 11771 12028 12074 12283 13645 13839 14352 14570 14745 14971 15296 16070 16132 16270 16400 17277 17903 18038 18487 18548 18606 18759 18826 18899 19043 19536 20300 22031 22297 22507 24146 24210 24213 24239 24291 24404 24424 24455 24475 25846 27371 28047 28276 28633 32201 34036 34537 36086 36468 38492 38990 40472 40599 41386 42036 43409 45228 47193https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AN/346/70005?format=asciiOpticaldefaultJ/AN/346/70005/table1Astrometry and Photometry of (C)TOIs & CompanionsrecnoRecord number assigned by the VizieR team.
