cds-question@unistra.freffective-temperaturestellar-agesstellar-massesstellar-radiiAsteroseismology with the Kepler space telescope is providing not only an improved characterization of exoplanets and their host stars, but also a new window on stellar structure and evolution for the large sample of solar-type stars in the field. We perform a uniform analysis of 22 of the brightest asteroseismic targets with the highest signal-to-noise ratio observed for 1 month each during the first year of the mission, and we quantify the precision and relative accuracy of asteroseismic determinations of the stellar radius, mass, and age that are possible using various methods. We present the properties of each star in the sample derived from an automated analysis of the individual oscillation frequencies and other observational constraints using the Asteroseismic Modeling Portal (AMP), and we compare them to the results of model-grid-based methods that fit the global oscillation properties. We find that fitting the individual frequencies typically yields asteroseismic radii and masses to ~1% precision, and ages to ~2.5% precision (respectively, 2, 5, and 8 times better than fitting the global oscillation properties). The absolute level of agreement between the results from different approaches is also encouraging, with model-grid-based methods yielding slightly smaller estimates of the radius and mass and slightly older values for the stellar age relative to AMP, which computes a large number of dedicated models for each star. The sample of targets for which this type of analysis is possible will grow as longer data sets are obtained during the remainder of the mission.2012ApJ...749..152Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/749/152CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/133 : Kepler Input Catalog (Kepler Mission Team, 2009)J/ApJS/199/30 : Effective temperature scale for KIC stars (Pinsonneault+, 2012)J/ApJ/746/16 : Modelling the convection zone (van Saders+, 2012)J/AJ/142/112 : KIC photometric calibration (Brown+, 2011)J/A+A/531/A124 : Visibilities of stellar oscillation modes (Ballot+, 2011)J/ApJ/729/L10 : KIC stars properties in NGC 6791 and NGC 6819 (Basu+, 2011)J/A+A/512/A54 : Teff and Fbol from Infrared Flux Method (Casagrande+, 2010)J/ApJ/718/L97 : Early asteroseismic results from Kepler (Van Grootel+, 2010)J/ApJ/469/355 : Teff, B-V and BC relation (Flower, 1996)http://amp.ucar.edu/ : The Asteroseismic Modeling Portal (AMP) Web sitehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/749/152https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/749/152http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/749/152https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/749/152https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/749/152http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/749/152GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/749/152/stars (Non-seismic constraints and physical parameters from AMP analysis)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/749/152/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/749/152/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/749/152/stars?GETtext/xml+votable180.050000true287.361813938.71401640.0055555555555555566/14581 14770 14771 14778 14918 14930 14931 14932 14935 14947 14948 14960 15044 15061 15106 15112 15124 15132 15133 15145 15156 15178https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/749/152?format=asciidefaultJ/ApJ/749/152/starsNon-seismic constraints and physical parameters from AMP analysisZ[0.003/0.05] Star metallicityphys.abund.ZfloatrecnoRecord number assigned by the VizieR team.
