cds-question@unistra.frstellar-massesstellar-agesstellar-radiistellar-distancechemical-abundancesWe use asteroseismic data from the Kepler satellite to determine fundamental stellar properties of the 66 main-sequence targets observed for at least one full year by the mission. We distributed tens of individual oscillation frequencies extracted from the time series of each star among seven modeling teams who applied different methods to determine radii, masses, and ages for all stars in the sample. Comparisons among the different results reveal a good level of agreement in all stellar properties, which is remarkable considering the variety of codes, input physics, and analysis methods employed by the different teams. Average uncertainties are of the order of ~2% in radius, ~4% in mass, and ~10% in age, making this the best-characterized sample of main-sequence stars available to date. Our predicted initial abundances and mixing-length parameters are checked against inferences from chemical enrichment laws {Delta}Y/{Delta}Z and predictions from 3D atmospheric simulations. We test the accuracy of the determined stellar properties by comparing them to the Sun, angular diameter measurements, Gaia parallaxes, and binary evolution, finding excellent agreement in all cases and further confirming the robustness of asteroseismically determined physical parameters of stars when individual frequencies of oscillation are available. Baptised as the Kepler dwarfs LEGACY sample, these stars are the solar-like oscillators with the best asteroseismic properties available for at least another decade. All data used in this analysis and the resulting stellar parameters are made publicly available for the community.2017ApJ...835..173Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/835/173CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/121 : Common proper motions stars in AGK3 (Halbwachs, 1986)V/133 : Kepler Input Catalog (Kepler Mission Team, 2009)J/A+A/275/101 : Chemical evolution of the galactic disk I.
