cds-question@unistra.freclipsing-binary-starsphotometrymultiple-starsWe report the discovery of a 61-Jupiter-mass brown dwarf (BD), which transits its F8V host star, WASP-30, every 4.16 days. From a range of age indicators we estimate the system age to be 1-2Gyr. We derive a radius (0.89+/-0.02R_Jup_) for the companion that is consistent with that predicted (0.914R_Jup_) by a model of a 1Gyr old, non-irradiated BD with a dusty atmosphere. The location of WASP-30b in the minimum of the mass-radius relation is consistent with the quantitative prediction of Chabrier & Baraffe, thus confirming the theory.2011ApJ...726L..19Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/726/L19CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/531/A60 : WASP-31b photometry and radial velocities (Anderson+, 2011)J/ApJ/718/1353 : Light curve of the triple system NLTT 41135 (Irwin+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/726/L19https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/726/L19http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/726/L19https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/726/L19https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/726/L19http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/726/L19GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/ApJ/726/L19/table2Euler photometry of WASP-30recnoRecord number assigned by the VizieR team.
