Abstract

We report the discovery of WASP-103 b, a new ultra-short-period planet (P = 22.2 h) transiting a 12.1 V-magnitude F8-type main-sequence star (1.22±0.04 M_⊙, 1.44_-0.03^+0.05 R_⊙, T_eff= 6110±160 K). WASP-103 b is significantly more massive (1.49±0.09 M_Jup) and larger (1.53_-0.07^+0.05 R_Jup) than Jupiter. Its large size and extreme irradiation (~ 9 x 10⁹ erg s^-1 cm^-2) 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.
