cds-question@unistra.frsolar-system-planetsvisible-astronomybroad-band-photometryinfrared-photometrymultiple-starsWe report new spectroscopic and photometric observations of the parent stars of the recently discovered transiting planets TrES-3 and TrES-4. A detailed abundance analysis based on high-resolution spectra yields [Fe/H]=-0.19+/-0.08, Teff=5650+/-75K, and logg=4.4+/-0.1 for TrES-3, and [Fe/H]=+0.14+/-0.09, Teff=6200+/-75K, and logg=4.0+/-0.1 for TrES-4. The accuracy of the effective temperatures is supported by a number of independent consistency checks. The spectroscopic orbital solution for TrES-3 is improved with our new radial velocity measurements of that system, as are the light-curve parameters for both systems based on newly acquired photometry for TrES-3 and a reanalysis of existing photometry for TrES-4. With these revised stellar parameters, we obtain improved values for the planetary masses and radii. We find M_p_=1.910^+0.075^_-0.080_M_Jup_, R_p_=1.336^+0.031^_-0.036_R_Jup_ for TrES-3, and M_p_=0.925+/-0.082M_Jup_, R_p_=1.783^+0.093^_-0.086_R_Jup_ for TrES-4. We confirm TrES-4 as the planet with the largest radius among the currently known transiting hot Jupiters.2009ApJ...691.1145Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/691/1145CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/AJ/136/267 : Six occultations of the exoplanet TrES-3 (Winn+, 2008)J/MNRAS/408/1494 : Planetary transits of TrES-2 and TrES-3 (Colon+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/691/1145https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/691/1145http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/691/1145https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/691/1145https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/691/1145http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/691/1145GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/ApJ/691/1145/table3Differential photometry of TrES-3TelTelescope used in observationinstr.setup;obscharrecnoRecord number assigned by the VizieR team.
