cds-question@unistra.frvariable-starssolar-system-planetsphotometryWe present photometry of the G0 star HAT-P-1 during six transits of its close-in giant planet, and we refine the estimates of the system parameters. Relative to Jupiter's properties, HAT-P-1b is 1.20+/-0.05 times larger, and its surface gravity is 2.7+/-0.2 times weaker. Although it remains the case that HAT-P-1b is among the least dense of the known sample of transiting exoplanets, its properties are in accord with previously published models of strongly irradiated, coreless, solar-composition giant planets. The times of the transits have a typical accuracy of 1 minute and do not depart significantly from a constant period.2007AJ....134.1707Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/134/1707CatalogResearchIsServedByTAP 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/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/134/1707https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/134/1707http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/134/1707https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/134/1707https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/134/1707http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/134/1707GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/AJ/134/1707/table1Photometry of HAT-P-1recnoRecord number assigned by the VizieR team.
