cds-question@unistra.frexoplanetsstellar-radiiastronomical-modelsThe properties of a transiting planet's host star are written in its transit light curve. The light curve can reveal the stellar density ({rho}_*_) and the limb-darkening profile in addition to the characteristics of the planet and its orbit. For planets with strong prior constraints on orbital eccentricity, we may measure these stellar properties directly from the light curve; this method promises to aid greatly in the characterization of transiting planet host stars targeted by the upcoming NASA Transiting Exoplanet Survey Satellite mission and any long-period, singly transiting planets discovered in the same systems. Using Bayesian inference, we fit a transit model, including a nonlinear limb-darkening law, to 66 Kepler transiting planet hosts to measure their stellar properties. We present posterior distributions of {rho}*, limb-darkening coefficients, and other system parameters for these stars. We measure densities to within 5% for the majority of our target stars, with the dominant precision-limiting factor being the signal-to-noise ratio of the transits. Of our measured stellar densities, 95% are in 3{sigma} or better agreement with previously published literature values. We make posterior distributions for all of our target Kepler objects of interest available online at 10.5281/zenodo.1028515.2017AJ....154..228Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/154/228CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/133 : Kepler Input Catalog (Kepler Mission Team, 2009)J/A+A/510/A21 : Stellar Limb-Darkening Coefficients (Sing, 2010)J/AJ/143/39 : Analysis of hot Jupiters in Kepler Q2 (Coughlin+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/154/228https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/154/228http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/154/228https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/154/228https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/154/228http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/154/228GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/154/228/catalog (Occultation targets (table 1) , tidally circularized ("tidal") targets (table 2) and compact multi-planet systems ("multis") (table 3))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/154/228/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/154/228/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/154/228/catalog?GETtext/xml+votable180.050000true286.808491449.31641420.0055555555555555566/14580 14581 14583 14584 14585 14589 14591 14733 14735 14746 14750 14751 14753 14760 14762 14765 14767 14768 14772 14779 14780 14783 14816 14818 14819 14826 14827 14923 14925 14929 14931 14935 14936 14942 14952 14958 14962 14963 14966 14969 14971 14973 15040 15104 15112 15118 15120 15122 15124 15126 15140 15143 15148 15153 15158 15159 15169 15171 15233https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/154/228?format=asciidefaultJ/AJ/154/228/catalogOccultation targets (table 1) , tidally circularized ("tidal") targets (table 2) and compact multi-planet systems ("multis") (table 3)SimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
