Abstract (from CDS):

We report the discovery of WASP-103b, a new ultra-short-period planet (P=22.2h) transiting a 12.1 V-magnitude F8-type main-sequence star (1.22±0.04M☉, 1.44–0.03+0.05R☉, Teff=6110±160K). WASP-103b is significantly more massive (1.49±0.09MJup) and larger (1.53–0.07+0.05RJup) than Jupiter. Its large size and extreme irradiation (∼9x109erg/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.
