cds-question@unistra.frasteroseismologygiant-starsvisible-astronomyTransiting Exoplanet Survey Satellite (TESS) has produced long-term photometry for millions of stars across the sky. In this work, we present an asteroseismic catalogue of 19151 red giants in the TESS Continuous Viewing Zones using sectors 1-87 (Years 1-7). We visually assessed the power spectra for oscillations, and then applied the computationally efficient nuSYD method to confirm reliability. We identified an increase of 80% in the number of previously known oscillating red giants at a TESS magnitude >8. We determined the frequency of maximum power (numax) and the large frequency separation (deltanu) using the pySYD pipeline, achieving typical precisions of 1.5% and 1.0%, respectively. We classified the stars into Red Giant Branch (RGB) and Core Helium Burning (CHeB) classes using a Convolutional Neural Network. Using spectroscopic data for 10,298 stars with reliable asteroseismic measurements, we have been able to measure stellar mass and radii with precisions of 7.5% and 2.8%, which is comparable to that from 4-yr Kepler data. A comparison of the seismic radii with Gaia radii shows excellent agreement. With three years of TESS data, the asteroseismic parameters are precise enough to identify the RGB bump and delineate the Zero Age Helium Burning edge. Combined with astrometric data, these parameters reveal established trends across the Galactic plane, providing a valuable set of uniformly determined asteroseismic parameters for Galactic Archaeology.2026MNRAS.548ag671Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/548/G671CatalogResearchIsServedByTAP 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/548/G671https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/548/G671http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/548/G671https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/548/G671https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/548/G671http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/548/G671GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/548/G671/table1 (Catalogue of asteroseismic parameters for 19151 oscillating red giants in the TESS CVZs)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/548/G671/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/548/G671/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/548/G671/table1?GETtext/xml+votable180.050000true279.630956777.69709220.0055555555555555566/https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/548/G671?format=asciiOpticaldefaultJ/MNRAS/548/G671/table1Catalogue of asteroseismic parameters for 19151 oscillating red giants in the TESS CVZsrecnoRecord number assigned by the VizieR team.
