TESS 20 second cadence flare J/A+A/689/A103 ivo://CDS.VizieR/J/A+A/689/A103 doi:10.26093/cds/vizier.36890103 CDS Zhang L. Yang Z. Su T. Han X.L.

We have used light curves from the TESS 20 second cadence survey from 2020 to 2023 to detect flare events, and determine their properties. By means of repeated fitting to distinguish stellar background light curves and flare events, we detected 32978 flare events associated with 5463 flaring stars. Furthermore, we cross-matched our samples with the Gaia and SDSS surveys, and obtained additional stellar parameters for determination of relationships between stellar and flare properties. We found that the durations of 55% of the studied flares were less than 8 minutes. Flare energies of the TESS 20 second cadence are usually smaller than those obtained by TESS 2-min cadence data. We identified 28425 flare events associated with4,784 flaring stars. The relationship between flare energy and duration for both giant and main sequence stars display a consistentV-shaped distribution. There is a positive correlation trend on both sides with 10^34^erg. Stars with lower effective temperature and mass generate more frequent flare events. In summary, it is necessary to detect more flare events with higher time resolution and our flare samples with 20-second cadence are important for discovering additional new properties. 2024A&A...689A.103Z https://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/689/A103 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to IV/38 : TESS Input Catalog - v8.0 (TIC-8) (Stassun+, 2019) J/A+A/669/A15 : TESS flare events and physical parameters (Yang+, 2023) https://cds.unistra.fr/vizier-org/licences_vizier.html https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/689/A103 https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/689/A103 http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/689/A103 https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/689/A103 https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/689/A103 http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/689/A103 GET text/xml+votable https://tapvizier.cds.unistra.fr/TAPVizieR/tap Cone search capability for table J/A+A/689/A103/tablea1 (Flare parameters of TESS 20 second cadence data for 5471 stars) https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/689/A103/tablea1? https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/689/A103/tablea1? http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/689/A103/tablea1?
