cds-question@unistra.frmultiple-starsexoplanetsstellar-distancestellar-radiiproper-motionsThe Transiting Exoplanet Survey Satellite (TESS) is finding transiting planet candidates around bright, nearby stars across the entire sky. The large field of view, however, results in low spatial resolution; therefore, multiple stars contribute to almost every TESS light curve. High angular resolution imaging can detect the previously unknown companions to planetary candidate hosts that dilute the transit depths, lead to host star ambiguity, and, in some cases, are the source of false-positive transit signals. We use speckle imaging on the Southern Astrophysical Research (SOAR) telescope to search for companions to 542 TESS planet candidate hosts in the southern sky. We provide correction factors for the 117 systems with resolved companions due to photometric contamination. The contamination in TESS due to close binaries is similar to that found in surveys of Kepler planet candidates. For the solar-type population, we find a deep deficit of close binary systems with projected stellar separations less than 100 au among planet candidate hosts (44 observed binaries compared to 124 expected based on field binary statistics). The close binary suppression among TESS planet candidate hosts is similar to that seen for the more distant Kepler population. We also find a large surplus of TESS planet candidates in wide binary systems detected in both SOAR and Gaia DR2 (Cat. I/345) (119 observed binaries compared to 77 expected). These wide binaries almost exclusively host giant planets, however, suggesting that orbital migration caused by perturbations from the stellar companion may lead to planet-planet scattering and suppress the population of small planets in wide binaries. Both trends are also apparent in the M dwarf planet candidate hosts.2020AJ....159...19Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/159/19CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/wds : The Washington Visual Double Star Catalog (Mason+, 2014)I/345 : Gaia DR2 (Gaia, 2018)I/347 : Distances to 1.33 billion stars in Gaia DR2 (Bailer-Jones+, 2018)IV/38 : TESS Input Catalog - v8.0 (TIC-8) (Stassun+, 2019)J/ApJ/809/77 : Transiting Exoplanet Survey Satellite (TESS) (Sullivan+, 2015)J/AJ/156/102 : The TESS Input Catalog and Candidate Target ListJ/AJ/158/243 : A search for multiplanet systems with TESS (Pearson, 2019)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/159/19https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/159/19http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/159/19https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/159/19https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/159/19http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/159/19GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/159/19/table6 (Full SOAR speckle observation list and binary properties)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/159/19/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/159/19/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/159/19/table6?GETtext/xml+votable180.050000true318.73713-55.871860.0055555555555555566/4161 16395 16405 16472 16481 16488-16489 16512 16518 16581 16633 16662 16722 16808 16840 16847 16851 16904 16938 16971 16987 17001-17002 17012 17072 17089 17106 17109 17120 17162 17166-17167 17185 17202 17225 17240 17253 17280 17287 17297 17300 17312-17313 17430 17605 17705 17774 17995 18012 18437 18452 20480 20538 20575 20613 20667 20692 20745 20758 20835 20843 20906 20977 21114 21125 21137 21176 21197 21199 21206 21227 21234 21259 21270 21346 21441 21766-21767 21824 22656 22661-22662 22691 22696 22709 22805 22885 23033 23178 23214 23252 23282 23460 24585 24889 24999 25145 25196 25401 25496 25635 26634 26637 26648 26727 26734 26840 27056 27163 27176 27184 27263 27358 32795 32811 32819 32830 32838 32848 32862 32872 32912-32913 32961 32975 32979-32980 32991 33004 33010 33022 33041 33045 33049 33070 33078 33085-33087 33093 33096 33098 33112-33113 33124 33126 33133-33134 33140 33145 33148 33151 33157 33169 33197 33200-33201 33207 33210 33212 33224 33230-33231 33241 33260 33279 33283 33285 33299 33386 33398 33426 33428 33449 33457 33466 33544 33564 33592 33598 33629 33652 33687 33702-33703 33733 33792 33805 33814 33818 33823-33824 33839-33840 33849 33851 33854 33861 33868 33874-33875 33883 33890 33892 33898 33900-33901 33903 33908 33914 33923 33932 33943 33954 33958-33959 33972-33973 33978 33984 33989 33995 34002 34005 34068 34186 34254 34264 34276 34281 34301 34341 34370 34421 34423 34441-34442 34448 34452 34468 34471 34578 34749 34751 34784 34820 34832 34843 34933 34937 34949 34955 34961 34986 35003 35018 35035 35057 35065 35087 35159 35210 35213 35240 35275 35346 35350 35371 35374 35381 35398 35406 35412 35434 35439 35486 35515 35517 35532 35534 35536 35551 35562 35575 35588 35592 35608 35624 35639 35668 35696 35841 35868 35914 35936 35938 35975 35985 35993 36015 36115 36191 36248 36348 36419 36525 36614 36643 36717 36746 36772 37049 37064 37157 37309 37313 37317 37351 37393 37398 37418 37422 37436 37448 37453 37472 37484 37497 37519 37530 37552 37594 37600 37611 37688 37713 37751 37828 37834-37835 37860 37886 37934 37989 38116 38206 38268 38287 38301 38315 38340 38345 38351 38376 38416 38437 38458 38480 38488 38493 38560 38615 38623 38644 38752 38914 38934 38942 38946 38954 38968 38977 38982 39007 39009 39012-39013 39042 39044-39045 39052 39059 39063 39126 39138-39139 39148 39198 39219-39220 39227 39231-39232 39247 39255 39258 39329 39331 39345 39349 39351 39356 39368 39396 39398 39408 39420 39452 39489 39512 39551 39569 39606 39623 39631 39652 39672 39683 39691 39697 39699 39764 39792 39844 39912 39938 39976 39981 40109 40129 40220 40222 40351 40456 40472 40480 40518 40526 40545 40571 40573 40833 41013 41015 41179 41255 41786 41995 42103 42296 42520 42659 42682 42865 42897 43065 43247 43378 43442 43551 43553 43580 43631 43668 43753 43771 43782 44011 44046 44272 44590 45372 45382 45515 45527 45539 45553 45922 45946 46088 46109 46128 46135 46160 46164 46242 46333 46356 46365 46394 46405 46414 46432 46437 46439 46462-46463 46544 46546 46549 46557 46561 46575 46616 46693 46738 46780 46854 46873 46887 46908 46913 46935 46959 46975 47058 47061 47094 48138 48160 48251 48327 48350 48353 48415https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/159/19?format=asciidefaultJ/AJ/159/19/table6Full SOAR speckle observation list and binary propertiesrecnoRecord number assigned by the VizieR team.
