cds-question@unistra.frmultiple-starssolar-system-planetsphotometryThe sample of hot Jupiters that have been studied in great detail is still growing. In particular, when the planet transits its host star, it is possible to measure the planetary radius and the planet mass (with radial velocity data). For the study of planetary atmospheres, it is essential to obtain transit and occultation measurements at multiple wavelengths. We aim to characterize the transiting hot Jupiter WASP-19b by deriving accurate and precise planetary parameters from a dedicated observing campaign of transits and occultations. We have obtained a total of 14 transit lightcurves in the r'-Gunn, I-Cousins, z'-Gunn, and I+z' filters and 10 occultation lightcurves in z'-Gunn using EulerCam on the Euler-Swiss telescope and TRAPPIST. We also obtained one lightcurve through the narrow-band NB1190 filter of HAWK-I on the VLT measuring an occultation at 1.19 micron. We performed a global MCMC analysis of all new data, together with some archive data in order to refine the planetary parameters and to measure the occultation depths in z'-band and at 1.19 micron. We measure a planetary radius of R_p_=1.376+/-0.046R_J_, a planetary mass of M_p_=1.165+/-0.068M_J_, and find a very low eccentricity of e=0.0077(-0.0032/+0.0068), compatible with a circular orbit. We have detected the z'-band occultation at 3 sigma significance and measure it to be delta_F_occ,z'=352+/-116ppm, more than a factor of 2 smaller than previously published. The occultation at 1.19 micron is only marginally constrained at delta_F_occ,NB1190=1711(-726/+745)ppm. We show that the detection of occultations in the visible range is within reach, even for 1m class telescopes if a considerable number of individual events are observed. Our results suggest an oxygen-dominated atmosphere of WASP-19b, making the planet an interesting test case for oxygen-rich planets without temperature inversion.2013A&A...552A...2Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/552/A2CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/MNRAS/408/1680 : Transiting planetary system WASP-2 (Southworth+, 2010)J/ApJ/715/421 : Relative photometry of WASP-3 (Tripathi+, 2010)J/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/A+A/530/A5 : WASP-4b thermal emission Ks-band detection (Caceres+, 2011)J/A+A/539/A159 : WASP-4b transit griz light curves (Nikolov+, 2012)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/527/A8 : Transiting planetary system WASP-7 (Southworth+, 2011)J/A+A/517/L1 : Radial velocities of WASP-8b planet (Queloz+, 2010)J/ApJ/692/L100 : Relative photometry of WASP-10 (Johnson+, 2009)J/A+A/535/A7 : Transit light curves of WASP-10 b (Maciejewski+, 2011)J/ApJ/720/872 : A spectropolarimetric analysis of WASP-12 (Fossati+, 2010)J/A+A/528/A65 : WASP-12b transits (Maciejewski+, 2011)J/AJ/141/179 : Transits of TrES-4b, HAT-P-3b and WASP-12b (Chan+, 2011)J/A+A/502/391 : WASP-13b photometry and radial velocities (Skillen+, 2009)J/ApJ/709/159 : Relative Ic photometry of WASP-17 (Anderson+, 2010)J/ApJ/707/167 : Transiting planetary system WASP-18 (Southworth+, 2009)J/A+A/513/L3 : WASP-19b H-band thermal emission (Anderson+, 2010)J/A+A/519/A98 : Transit of exoplanet WASP-21b (Bouchy+, 2010)J/A+A/534/A16 : WASP-22 & WASP-26 photometry & velocities (Anderson+, 2011)J/A+A/531/A24 : WASP-23 photometric and radial velocity data (Triaud+, 2011)J/A+A/520/A56 : WASP-26b RV and photometric data (Smalley+, 2010)J/ApJ/726/L19 : Gunn r photometry of WASP-30 (Anderson+, 2011)J/A+A/531/A60 : WASP-31b photometry and radial velocities (Anderson+, 2011)J/A+A/526/L10 : Transits of WASP-33 (Herrero+, 2011)J/A+A/526/A130 : WASP-34b photometry and radial velocities (Smalley+, 2011)J/A+A/525/A54 : Transits of WASP-38b (Barros+, 2011)J/A+A/531/A40 : Transits of WASP-39b (Faedi+, 2011)J/A+A/542/A4 : WASP-43b thirty eclipses (Gillon+, 2012)J/A+A/544/A72 : WASP-42 and WASP-49 photometry and velocities (Lendl+, 2012)J/A+A/533/A88 : WASP-50b photometry and radial velocities (Gillon+, 2011)J/A+A/547/A61 : WASP78 and WASP79 RV and photometric data (Smalley+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/552/A2https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/552/A2http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/552/A2https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/552/A2https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/552/A2http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/552/A2GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/552/A2/eulericEulerCam photometry (I Cousins filter)AMAirmassobs.airMassfloatrecnoRecord number assigned by the VizieR team.
