cds-question@unistra.fra-starsvariable-starsasteroseismologyeffective-temperaturevisible-astronomyWe present the first asteroseismic results for {delta} Scuti and {gamma} Doradus stars observed in Sectors 1 and 2 of the TESS mission. We utilize the 2-min cadence TESS data for a sample of 117 stars to classify their behaviour regarding variability and place them in the Hertzsprung-Russell diagram using Gaia DR2 data. Included within our sample are the eponymous members of two pulsator classes, {gamma} Doradus and SX Phoenicis. Our sample of pulsating intermediate-mass stars observed by TESS also allows us to confront theoretical models of pulsation driving in the classical instability strip for the first time and show that mixing processes in the outer envelope play an important role. We derive an empirical estimate of 74 per cent for the relative amplitude suppression factor as a result of the redder TESS passband compared to the Kepler mission using a pulsating eclipsing binary system. Furthermore, our sample contains many high-frequency pulsators, allowing us to probe the frequency variability of hot young {delta} Scuti stars, which were lacking in the Kepler mission data set, and identify promising targets for future asteroseismic modelling. The TESS data also allow us to refine the stellar parameters of SX Phoenicis, which is believed to be a blue straggler.2019MNRAS.490.4040Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/490/4040CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIV/38 : TESS Input Catalog - v8.0 (TIC-8) (Stassun+, 2019)I/345 : Gaia DR2 (Gaia Collaboration, 2018)I/311 : Hipparcos, the New Reduction (van Leeuwen, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/490/4040https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/490/4040http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/490/4040https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/490/4040https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/490/4040http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/490/4040GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/490/4040/tablea1 (Stellar parameters for the TESS {delta} Sct and {gamma} Dor pulsators observed at 2-min cadence during the first two pointings in the ecliptic Southern hemisphere)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/490/4040/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/490/4040/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/490/4040/tablea1?GETtext/xml+votable180.050000true357.1917308-8.14571060.0055555555555555566/16424 16435 16445 16486 16497 16587 16597 16611 16617 16906 16915 16976 17037 17111 17156 17311-17312 18444 32789 32793 32816 32831 32919 32974 32982 32985 33037 33077 33224-33225 33276 33298 33326 33332 33424 33429 33437 33447 33465 33469 33522 33535 33570 33716 33732 33865 33874 33952 34839 34858 34897 34926 34976 35053 35082 35104 35426 35447 35483 35541 35548 37498 37586 38922 38924 38929 38942 38959 39010 39052 39076 45426 45539 45543 45876 45896 45900 45927 45941 46053 46079 46181 46234 46238 46250 46294 46363 46372 46419 46425 46482 46496 46562 46572 46630 46680 46692 46704 46711 46720 46744 46800 46911-46912 46939 46979 47027 47037 47069 48153 48205 48285 48352 48361 48417 48517https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/490/4040?format=asciiOpticaldefaultJ/MNRAS/490/4040/tablea1Stellar parameters for the TESS {delta} Sct and {gamma} Dor pulsators observed at 2-min cadence during the first two pointings in the ecliptic Southern hemisphereNameStar namemeta.idcharSimbadSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
