cds-question@unistra.frf-starsvisible-astronomyWe present stellar parameter estimates for 939457 southern FGK stars that are candidate targets for the Transiting Exoplanet Survey Satellite (TESS) mission. Using a data-driven method similar to the CANNON, we build a model of stellar colours as a function of stellar parameters. We then use these in combination with stellar evolution models to estimate the effective temperature, gravity, metallicity, mass, radius, and extinction for our selected targets. Our effective temperature estimates compare well with those from spectroscopic surveys and the addition of Gaia DR2 parallaxes allows us to identify subgiant interlopers into the TESS sample. We are able to estimate the radii of TESS targets with a typical uncertainty of 9.3 per cent. This catalogue can be used to screen exoplanet candidates from TESS and provides a homogeneous set of stellar parameters for statistical studies.2019MNRAS.486..251Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/486/251CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/345 : Gaia DR2 (Gaia Collaboration, 2018)IV/39 : TESS Input Catalog version 8.2 (TIC v8.2) (Paegert+, 2021)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/486/251https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/486/251http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/486/251https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/486/251https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/486/251http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/486/251GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/486/251/tablea1 (Matched Gaia detections for TESS CTL objects)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/486/251/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/486/251/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/486/251/tablea1?GETtext/xml+votable180.050000true329.03633772213-10.966926863620.0055555555555555560/0-11 6/1.9867573869263685e-19 3.916500758235022e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/486/251?format=asciiOpticaldefaultJ/MNRAS/486/251/tablea1Matched Gaia detections for TESS CTL objectsNameTESS Input Catalog identifiermeta.id;meta.mainlong_RA.icrsRight ascension (ICRS) at Epoch=J2000, proper motions taken into accountdegpos.eq.raindexed_DE.icrsDeclination (ICRS) at Epoch=J2000, proper motions taken into accountdegpos.eq.decindexedrecnoRecord number assigned by the VizieR team.
