cds-question@unistra.frmultiple-starssolar-system-planetsstellar-massesWe present a study of 33 Kepler planet-candidate host stars for which asteroseismic observations have sufficiently high signal-to-noise ratio to allow extraction of individual pulsation frequencies. We implement a new Bayesian scheme that is flexible in its input to process individual oscillation frequencies, combinations of them, and average asteroseismic parameters, and derive robust fundamental properties for these targets. Applying this scheme to grids of evolutionary models yields stellar properties with median statistical uncertainties of 1.2 per cent (radius), 1.7 per cent (density), 3.3 per cent (mass), 4.4 per cent (distance), and 14 per cent (age), making this the exoplanet host-star sample with the most precise and uniformly determined fundamental parameters to date. We assess the systematics from changes in the solar abundances and mixing-length parameter, showing that they are smaller than the statistical errors. We also determine the stellar properties with three other fitting algorithms and explore the systematics arising from using different evolution and pulsation codes, resulting in 1 per cent in density and radius, and 2 per cent and 7 per cent in mass and age, respectively. We confirm previous findings of the initial helium abundance being a source of systematics comparable to our statistical uncertainties, and discuss future prospects for constraining this parameter by combining asteroseismology and data from space missions. Finally, we compare our derived properties with those obtained using the global average asteroseismic observables along with effective temperature and metallicity, finding excellent level of agreement. Owing to selection effects, our results show that the majority of the high signal-to-noise ratio asteroseismic Kepler host stars are older than the Sun.2015MNRAS.452.2127Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/452/2127CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/133 : Kepler Input Catalog (Kepler Mission Team, 2009)J/ApJ/767/127 : Asteroseismic solutions for 77 Kepler stars (Huber+, 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/452/2127https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/452/2127http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/452/2127https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/452/2127https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/452/2127http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/452/2127GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/452/2127/table3 (Recommended set of stellar properties and statistical uncertainties of exoplanet candidate host stars as determined with BASTA)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/452/2127/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/452/2127/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/452/2127/table3?GETtext/xml+votable180.050000true292.2473447.96951780.0055555555555555566/14585 14782 14918 14921 14924 14929-14931 14933 14936-14937 14959 14961 14968-14970 15060 15107 15112 15120-15121 15129-15131 15134 15145 15149 15155https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/452/2127?format=asciidefaultJ/MNRAS/452/2127/table3Recommended set of stellar properties and statistical uncertainties of exoplanet candidate host stars as determined with BASTAKICKIC numbermeta.id;meta.mainintTeffEffective temperatureKphys.temperature.effectiveinte_Teffrms uncertainty on Teff (1)Kstat.error;phys.temperature.effectiveint[Fe/H]Metallicityphys.abund.Zfloate_[Fe/H]rms uncertainty on [Fe/H] (1)stat.error;phys.abund.FefloatMassMasssolMassphys.massfloatE_Massrms uncertainty on Mass (1)solMassstat.error;stat.maxfloate_MassRadius (1)solMassstat.error;phys.massfloatRadiusrms uncertainty on RadiussolRadphys.angSize;srcfloatE_RadiusError on radius (upper value) (1)solRadstat.error;stat.maxfloate_RadiusError on radius (lower value) (1)solRadstat.error;phys.size.radiusfloatrhoDensityg.cm**-3src.densityfloatE_rhoError on rho (upper value) (1)g.cm**-3stat.error;stat.maxfloate_rhoError on rho (lower value) (1)g.cm**-3stat.errorfloatloggSurface gravitylog(cm.s**-2)phys.gravityfloatE_loggError on logg (upper value) (1)log(cm.s**-2)stat.error;stat.maxfloate_loggError on logg (lower value) (1)log(cm.s**-2)stat.errorfloatLLuminosity (2)solLumphys.luminosityfloatE_LError on L (upper value) (1)solLumstat.error;stat.maxfloate_LError on L (lower value) (1)solLumstat.errorfloatE_AgeError on Age (upper value) (1)Gyrstat.error;stat.maxfloate_AgeError on Age (lower value) (1)Gyrstat.error;time.agefloatDistDistancepcpos.distancefloatE_DistError on Dist (upper value) (1)pcstat.error;stat.maxfloate_DistError on Dist (lower value) (1)pcstat.errorfloatNotesLiterature sources of confirmed or validated exoplanetsmeta.notecharn_Notes[b] Note (3)meta.notecharRefReference(s)meta.ref;pos.framecharSimbadSimbad column added by the CDSmeta.ref.urlchar_RARight Ascension (J2000) from SIMBAD (not part of the original data)degpos.eq.ra;meta.main_DEDeclination (J2000) from SIMBAD (not part of the original data)degpos.eq.dec;meta.mainAgeAgeGyrtime.agefloatrecnoRecord number assigned by the VizieR team.
