cds-question@unistra.frmultiple-starssolar-system-planetsinfrared-photometryOnly recently it has become possible to measure the thermal emission from hot-Jupiters at near-Infrared wavelengths using ground-based telescopes, by secondary eclipse observations. This allows the planet flux to be probed around the peak of its spectral energy distribution, which is vital for the understanding of its energy budget. The aim of the reported work is to measure the eclipse depth of the planet HAT-P-1b at 2.2micron. This planet is an interesting case, since the amount of stellar irradiation it receives falls in between that of the two best studied systems (HD209458 and HD189733), and it has been suggested to have a weak thermal inversion layer. We have used the LIRIS instrument on the William Herschel Telescope (WHT) to observe the secondary eclipse of HAT-P-1b in the Ks-band, as part of our Ground-based secondary eclipse (GROUSE) project. The observations were done in staring mode, while significantly defocusing the telescope to avoid saturation on the K=8.4 star. With an average cadence of 2.5 seconds, we collected 6520 frames during one night.2011A&A...528A..49Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/528/A49CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/AJ/134/1707 : Six transits of exoplanet HAT-P-1b (Winn+, 2007)J/A+A/523/A84 : Transit light curves of HAT-P-13b (Szabo+, 2010)J/A+A/527/A85 : Light curves of HAT-P-3b and HAT-P-14b (Nascimbeni+, 2011)J/A+A/550/A54 : Ks-band observations of WASP-33b (de Mooij+, 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/528/A49https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/528/A49http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/528/A49https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/528/A49https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/528/A49http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/528/A49GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapInfrareddefaultJ/A+A/528/A49/hatp1_ksKs-band time-series photometry of HAT-P-1brecnoRecord number assigned by the VizieR team.
