cds-question@unistra.frmultiple-starsproper-motionsvisible-astronomytrigonometric-parallaxstellar-massesThe latest results from our ongoing multiplicity study of (Community) TESS Objects of Interest are presented, using astro- and photometric data from the ESA-Gaia mission, to detect stellar companions of these stars and characterize their properties. A total of 124 binary and 7 hierarchical triple star systems were detected among 2175 targets, whose multiplicity was investigated in the course of our survey, which are located at distances closer than about 500 pc around the Sun. The detected companions and the targets are located at the same distance and share a common proper motion, as expected for components of gravitationally bound stellar systems, as proven with their accurate Gaia EDR3 astrometry. The companions have masses in the range between about 0.09 and 2.5M_{sun}_ and are most frequently found in the mass range between 0.15 and 0.8M_{sun}_. The companions exhibit projected separations to the targets between about 50 to 9700au and their frequency is the highest and constant up to about 500au, while it decreases for larger projected separations. In addition to mainly mid M to early K dwarfs, 4 white dwarf companions were detected in this survey, whose true nature could be identified with their photometric properties.2022AN....34324017Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AN/343/24017CatalogResearchIsServedByTAP 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/AN/342/840 : Stellar companions of (C)TOIs (Mugrauer+, 2021)J/other/FrASS/8.624907 : (Sub)Stellar companions of exoplanet hostshttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AN/343/24017https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AN/343/24017http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AN/343/24017https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AN/343/24017https://vizier.iucaa.in/viz-bin/votable?-source=J/AN/343/24017http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AN/343/24017GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AN/343/24017/table3 (Equatorial Coordinates & Properties of Companions)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AN/343/24017/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AN/343/24017/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AN/343/24017/table3?GETtext/xml+votable180.050000true353.8350692912-64.556358237330.0055555555555555566/502 1830 2364 2626 2802 3033 3036 3047 3484 3514 3611 4040 5755 6610 6693 6971 7787 10068 10097 10226 10776 11279 11482 11943 12014 12971 13493 13564 13801 14351 14696 14801 15129 15132 15199 15219 15247 15399 15643 16007 16022 16079 16215 16619 17819 20535 20579 20741 20835 20977 21391 21501 21528 21638 21644 21921 22459 22584 22736 22820 23013 23264 23277 23451 24878 24889 26019 27142 27328 28279 32749 32935 32959 32975 33260 33395 33598 33861 34121 34159 34187 34370 34516 34599 34751 34780 34996 36640 36712 37033 37375 37488 37570 37670 37748 37756 37828 37877 37880 37886 38746 39052 39209 39219 39626 39691 39909 40119 40141 40347 40356 40456 41134 42005 42362 43111 43932 44056 45498 45632 46088 46217 46463 46549 46575 46816 46881 46952 47000 47810 48005https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AN/343/24017?format=asciiOpticaldefaultJ/AN/343/24017/table1Astro- & Photometry of (C)TOIs & CompanionsrecnoRecord number assigned by the VizieR team.
