cds-question@unistra.frg-starssolar-system-planetsradial-velocityccd-photometryWe report the discovery of WASP-78b and WASP-79b, two highly-bloated Jupiter-mass exoplanets orbiting F-type host stars. WASP-78b orbits its V=12.0 host star (TYC 5889-271-1) every 2.175 days and WASP-79b orbits its V=10.1 host star (CD-30 1812) every 3.662 days. Planetary parameters have been determined using a simultaneous fit to WASP and TRAPPIST transit photometry and CORALIE radial-velocity measurements. For WASP-78b a planetary mass of 0.89+/-0.08M_Jup_ and a radius of 1.70+/-0.11R_Jup_ is found. The planetary equilibrium temperature of T_P_=2350+/-80K for WASP-78b makes it one of the hottest of the currently known exoplanets. WASP-79b its found to have a planetary mass of 0.90+/-0.08M_Jup_, but with a somewhat uncertain radius due to lack of sufficient TRAPPIST photometry. The planetary radius is at least 1.70+/-0.11R_Jup_, but could be as large as 2.09+/-0.14R_Jup_, which would make WASP-79b the largest known exoplanet.2012A&A...547A..61Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/547/A61CatalogResearchIsServedByTAP 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/A+A/530/A5 : WASP-4b Ks-band thermal emission detection (Caceres+, 2011)J/A+A/539/A159 : WASP-4b transit griz light curves (Nikolov+, 2012)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/527/A8 : Transiting planetary system WASP-7 (Southworth+, 2011)J/A+A/517/L1 : Radial velocities of WASP-8b planet (Queloz+, 2010)J/A+A/535/A7 : Transit light curves of WASP-10 b (Maciejewski+, 2011)J/ApJ/692/L100 : Relative photometry of WASP-10 (Johnson+, 2009)J/A+A/528/A65 : WASP-12b transits (Maciejewski+, 2011)J/ApJ/720/872 : A spectropolarimetric analysis of WASP-12 (Fossati+, 2010)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/544/A72 : WASP-42 and WASP-49 photometry and velocities (Lendl+, 2012)J/A+A/542/A4 : WASP-43b thirty eclipses (Gillon+, 2012)J/A+A/533/A88 : WASP-50b photometry and radial velocities (Gillon+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/547/A61https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/547/A61http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/547/A61https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/547/A61https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/547/A61http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/547/A61GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/547/A61/rvWASP78 and WASP79 radial velocity and line bisector spansrecnoRecord number assigned by the VizieR team.
