cds-question@unistra.frastronomical-modelsdwarf-starsg-starsThe Kepler space telescope yielded unprecedented data for the study of solar-like oscillations in other stars. The large samples of multi-year observations posed an enormous data analysis challenge that has only recently been surmounted. Asteroseismic modeling has become more sophisticated over time, with better methods gradually developing alongside the extended observations and improved data analysis techniques. We apply the latest version of the Asteroseismic Modeling Portal (AMP) to the full-length Kepler data sets for 57 stars, comprising planetary hosts, binaries, solar-analogs, active stars, and for validation purposes, the Sun. From an analysis of the derived stellar properties for the full sample, we identify a variation of the mixing-length parameter with atmospheric properties. We also derive a linear relation between the stellar age and a characteristic frequency separation ratio. In addition, we find that the empirical correction for surface effects suggested by Kjeldsen and coworkers is adequate for solar-type stars that are not much hotter (Teff<~6200K) or significantly more evolved (logg>~4.2, <{Delta}{nu}> >~80uHz80) than the Sun. Precise parallaxes from the Gaia mission and future observations from TESS and PLATO promise to improve the reliability of stellar properties derived from asteroseismology.2017A&A...601A..67Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/601/A67CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/133 : Kepler Input Catalog (Kepler Mission Team, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/601/A67https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/601/A67http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/601/A67https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/601/A67https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/601/A67http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/601/A67GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/601/A67/tablea (Spectroscopic constraints and complementary data of the Kepler targets and the Sun, reference models and derived stellar properties using VIRGO data (Tables A1-A3 of the paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/601/A67/tablea?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/601/A67/tablea?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/601/A67/tablea?GETtext/xml+votable180.050000true6/14578 14581 14751 14757 14759 14763 14765 14767 14770-14771 14776 14778-14782 14918 14921 14930-14932 14935 14937 14939 14948 14959-14960 14962-14963 14966-14967 14969 15044 15061-15062 15106 15109 15112 15121 15123 15129 15131 15145-15146 15156 15168 15171-15174 15178https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/601/A67?format=asciidefaultJ/A+A/601/A67/tableaSpectroscopic constraints and complementary data of the Kepler targets and the Sun, reference models and derived stellar properties using VIRGO data (Tables A1-A3 of the paper)recnoRecord number assigned by the VizieR team.
