cds-question@unistra.frvariable-starssolar-system-planetsphotometryOf the nearby transiting exoplanets that are amenable to detailed study, TrES-2 is both the most massive and the one with the largest impact parameter. We present z-band photometry of three transits of TrES-2. We improve on the estimates of the planetary, stellar, and orbital parameters, in conjunction with the spectroscopic analysis of the host star by Sozzetti and coworkers. We find the planetary radius to be Rp=1.222+/-0.038R_Jup_ and the stellar radius to be R*=1.003+/-0.027R_{sun}_. The quoted uncertainties include the systematic error due to the uncertainty in the stellar mass (M*=0.980+/-0.062 M_{sun}_) The timings of the transits have an accuracy of 25s and are consistent with a uniform period, thus providing a baseline for future observations with the NASA Kepler satellite, whose field of view will include TrES-2.2007ApJ...664.1185Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/664/1185CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJ/652/1715 : Four transits of the exoplanet XO-1b (Holman+, 2006)J/AJ/133/11 : Photometry of OGLE-TR 111 (Winn+, 2007)J/ApJ/657/1098 : Transit of TrES-1 (Winn+, 2007)J/AJ/133/1828 : Transit light curves of HD 189733 (Winn+, 2007)J/AJ/134/1707 : Six transit of exoplanet HAT-P-1b (Winn+, 2007)J/AJ/136/267 : Six occultations of the exoplanet TrES-3 (Winn+, 2008)J/ApJ/683/1076 : Transits of exoplanet XO-3b (Winn+, 2008)J/ApJ/693/794 : Transit of exoplanet HD 17156b (Winn+, 2009)J/AJ/137/3826 : Two transits of the giant planet WASP-4b (Winn+, 2009)J/AJ/137/4911 : Six transits of the exoplanet XO-2b (Fernandez+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/664/1185https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/664/1185http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/664/1185https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/664/1185https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/664/1185http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/664/1185GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/ApJ/664/1185/table1Relative Photometry of TrES-2recnoRecord number assigned by the VizieR team.
