cds-question@unistra.frmultiple-starssolar-system-planetsWe present z-band photometry of three consecutive transits of the exoplanet TrES-1, with an accuracy of 0.15% and a cadence of 40s. We improve on estimates of the system parameters, finding in particular that the planetary radius is 1.081+/-0.029R_Jup_ and the stellar radius is 0.011+/-0.020R_{sun}_. The uncertainties include both the statistical error and the systematic error arising from the uncertainty in the stellar mass. The transit times are determined to within about 15s and allow us to refine the estimate of the mean orbital period: P=3.0300737+/-0.0000026days. We find no evidence for starspots or other irregularities that have been previously reported.2007ApJ...657.1098Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/657/1098CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/458/997 : Abundances for 6 transiting planet host stars (Santos+, 2006)J/AJ/131/2274 : Tres-1 equivalent widths (Sozzetti+, 2006)J/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/655/1103 : Five transits of the exoplanet OGLE-TR-10b (Holman+, 2007)J/AJ/133/1828 : Transit light curves of HD 189733 (Winn+, 2007)J/ApJ/664/1185 : Three transits of the exoplanet TrES-2 (Holman+, 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/657/1098https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/657/1098http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/657/1098https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/657/1098https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/657/1098http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/657/1098GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/ApJ/657/1098/table1Photometry of TrES-1RFluxRelative fluxphot.flux;arith.ratiodoublerecnoRecord number assigned by the VizieR team.
