cds-question@unistra.freclipsing-binary-starsmultiple-starssolar-system-planetsphotometryradial-velocityWe report the discovery of WASP-103 b, a new ultra-short-period planet (P=22.2h) transiting a 12.1 V-magnitude F8-type main-sequence star (1.22+/-0.04M_{sun}_, 1.44_-0.03_^+0.05^R_{sun}_, Teff=6110+/-160K). WASP-103 b is significantly more massive (1.49+/-0.09M_Jup_) and larger (1.53_-0.07_^+0.05^R_Jup_) than Jupiter. Its large size and extreme irradiation (~9x10^9^erg/s/cm2) make it an exquisite target for a thorough atmospheric characterization with existing facilities. Furthermore, its orbital distance is less than 20% larger than its Roche radius, meaning that it might be significantly distorted by tides and might experience mass loss through Roche-lobe overflow. It thus represents a new key object for understanding the last stage of the tidal evolution of hot Jupiters.2014A&A...562L...3Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/562/L3CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/559/A36 : Discovery of WASP-65b and WASP-75b (Gomez Maqueo Chew+, 2013)J/A+A/552/A82 : WASP-64b and WASP-72b light curves (Gillon+, 2013)J/A+A/547/A61 : WASP78 and WASP79 RV and photometric data (Smalley+, 2012)J/A+A/551/A80 : WASP-80 photometric and radial velocity data (Triaud+, 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/562/L3https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/562/L3http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/562/L3https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/562/L3https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/562/L3http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/562/L3GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/562/L3/waspWASP survey photometryrecnoRecord number assigned by the VizieR team.
