cds-question@unistra.freclipsing-binary-starssolar-system-planetsradial-velocityphotometryWe report the discovery of the low-density, transiting giant planet WASP-31b. The planet is 0.48 Jupiter masses and 1.55 Jupiter radii. It is in a 3.4-day orbit around a metal-poor, late-F-type, V=11.7 dwarf star, which is a member of a common proper motion pair. In terms of its low density, WASP-31b is second only to WASP-17b, which is a more highly irradiated planet of similar mass.2011A&A...531A..60Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/531/A60CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/MNRAS/408/1680 : Transiting planetary system WASP-2 (Southworth+, 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/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/ApJ/692/L100 : Relative photometry of WASP-10 (Johnson+, 2009)J/A+A/528/A65 : WASP-12b transits (Maciejewski+, 2011)J/A+A/502/391 : WASP-13b photometry and radial velocities (Skillen+, 2009)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/520/A56 : WASP-26b RV and photometric data (Smalley+, 2010)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)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/531/A60https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/531/A60http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/531/A60https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/531/A60https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/531/A60http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/531/A60GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/531/A60/phot*WASP-31 deredenned and normalised differential survey photometry from WASP-South and follow-up photometry from FTN/fs03 and EulerrecnoRecord number assigned by the VizieR team.
