cds-question@unistra.frmultiple-starssolar-system-planetsexoplanetsPrevious secondary eclipse observations of the hot Jupiter Qatar-1b in the Ks band suggest that it may have an unusually high day side temperature, indicative of minimal heat redistribution. There have also been indications that the orbit may be slightly eccentric, possibly forced by another planet in the system. We investigate the day side temperature and orbital eccentricity using secondary eclipse observations with Spitzer. We observed the secondary eclipse with Spitzer/IRAC in subarray mode, in both 3.6 and 4.5um wavelengths. We used pixel-level decorrelation to correct for Spitzer's intra-pixel sensitivity variations and thereby obtain accurate eclipse depths and central phases.2018A&A...610A..55Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/610/A55CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/554/A28 : Qatar-1 differential light curve (Covino+, 2013)J/A+A/555/A92 : Transit timing variations on Qatar-1 (von Essen+, 2013)J/A+A/577/A109 : Transit times of Qatar-1b (Maciejewski+, 2015)J/A+A/595/A61 : Detection of the secondary eclipse of Qatar-1b (Cruz+, 2016)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/610/A55https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/610/A55http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/610/A55https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/610/A55https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/610/A55http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/610/A55GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/610/A55/lcch1Qatar1 3.6 micron eclipsePhasePhasetime.phasedoublerecnoRecord number assigned by the VizieR team.
