cds-question@unistra.frvariable-starssolar-system-planetsphotometryWe present transit photometry of three exoplanets, TrES-4b, HAT-P-3b, and WASP-12b, allowing for refined estimates of the systems' parameters. TrES-4b and WASP-12b were confirmed to be "bloated" planets, with radii of 1.706+/-0.056R_Jup_ and 1.736+/-0.092R_Jup_, respectively. These planets are too large to be explained with standard models of gas giant planets. In contrast, HAT-P-3b has a radius of 0.827+/-0.055R_Jup_, smaller than a pure hydrogen-helium planet and indicative of a highly metal-enriched composition. Analyses of the transit timings revealed no significant departures from strict periodicity. For TrES-4, our relatively recent observations allow for improvement in the orbital ephemerides, which is useful for planning future observations.2011AJ....141..179Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/141/179CatalogResearchIsServedByTAP 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/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/AJ/141/179https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/141/179http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/141/179https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/141/179https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/141/179http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/141/179GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/AJ/141/179/table2Photometry of TrES-4 in irecnoRecord number assigned by the VizieR team.
