cds-question@unistra.freclipsing-binary-starssolar-system-planetsradial-velocityphotometryWe present the first ground-based detection of thermal emission from an exoplanet in the H-band. Using HAWK-I on the VLT, we observed an occultation of WASP-19b by its G8V-type host star. WASP-19b is a Jupiter-mass planet with an orbital period of only 19 h, and thus, being highly irradiated, is expected to be hot. We measure an H-band occultation depth of (0.259^+0.046^_-0.044_)%, which corresponds to an H-band brightness temperature of T_H_=2580+/-125K. A cloud-free model of the planet's atmosphere, with no redistribution of energy from day-side to night-side, under predicts the planet/star flux density ratio by a factor of two. As the stellar parameters, and thus the level of planetary irradiation, are well-constrained by measurement, it is likely that our model of the planet's atmosphere is too simple.2010A&A...513L...3Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/513/L3CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/MNRAS/399/287 : Transiting planetary system WASP-4 (Southworth+, 2009)J/AJ/137/3826 : Two transits of the giant planet WASP-4b (Winn+, 2009)J/MNRAS/396/1023 : Transiting planetary system WASP-5 (Southworth+, 2009)J/A+A/501/785 : Discovery and characterization of WASP-6b (Gillon+, 2009)J/A+A/502/395 : WASP-11b (West+, 2009)J/A+A/502/391 : WASP-13b photometry and radial velocities (Skillen+, 2009)J/ApJ/707/167 : Transiting planetary system WASP-18 (Southworth+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/513/L3https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/513/L3http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/513/L3https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/513/L3https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/513/L3http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/513/L3GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/513/L3/hawkihdDetrended HAWK-I H-band photometryrecnoRecord number assigned by the VizieR team.
