cds-question@unistra.frvariable-starsdwarf-starsThe theory of stellar evolution presents shortcomings when confronted with asteroseismic probes of interior physical properties. The differences between observations and theory are often great because stellar models have mainly been calibrated from observables connected to the surface of stars. Period-spacing patterns caused by gravity modes are a particularly powerful asteroseismic tool that are useful for probing the near-core rotation and mixing of chemical elements in main-sequence stars with convective cores. We aim to compose a catalog of intermediate-mass stars in the Transiting Exoplanet Survey Satellite (TESS) southern continuous viewing zone (CVZ) to reveal period-spacing patterns caused by gravity modes for use in future asteroseismic modeling. TESS full frame images (FFI) were inspected to select stars of intermediate- and high-mass using color-magnitude criteria. Light curves were extracted from custom masks per star, adopting stringent constraints on the aperture masks and contamination. The extracted light curves were subject to iterative prewhitening to detect gravity modes. We developed a method relying on the assumption that period spacings are an approximately linear function of the mode periods to build a template pattern. This template was used to extract the patterns and their uncertainties, relying on a bootstrap approach. Our TESS catalog of high-quality period-spacing patterns is the first of its kind and contains 140 gravity-mode patterns in 106 {gamma} Dor stars and two slowly pulsating B-type (SPB) stars. Half of these patterns contain seven or more measured mode periods and the longest pattern contains 20 modes. We provide the community with a convenient software tool to search for period-spacing patterns and to process the extracted light curves. Our catalog offers a fruitful starting point for future gravity-mode asteroseismology of rotating dwarfs with convective cores in the southern hemisphere.2022A&A...662A..82Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/662/A82CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIV/38 : TESS Input Catalog - v8.0 (TIC-8) (Stassun+, 2019)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/662/A82https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/662/A82http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/662/A82https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/662/A82https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/662/A82http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/662/A82GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/662/A82/tablea2 (Period-spacing patterns catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/662/A82/tablea2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/662/A82/tablea2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/662/A82/tablea2?GETtext/xml+votable180.050000true62.8537175-71.13339720.0055555555555555565/9729 6/32884 32893 33026 33029 33033 33036 33046 33055 33061 33064 33067 33080 33082 33113 33125 33134 33146 33158 33227 33799 33801 33809 33811 33814 33819-33821 33833 33846 33852 33861 33865 33870 33876 33880 37033 37048 37388 37398 37400-37402 37412-37413 37415 37418 37424-37425 37427 37429 37434 37438 37451 37474 37481 37483-37484 37507 37511 37520 37522 37526-37527 37535 37540 37557 37559 37565 37570 37574 37576-37577 37582 37609 37612 38921 38927 38929 38931 38941 38943-38944 38950 38953-38955 38957-38958 38960 38967 38974 38984 39041 39053 39076https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/662/A82?format=asciidefaultJ/A+A/662/A82/tablea2Period-spacing patterns cataloge_alphaOne-sigma negative error of alphastat.error;pos.eq.radoublerecnoRecord number assigned by the VizieR team.
