WASP-92b, WASP-93b and WASP-118b: three new transiting close-in giant planets

We present the discovery of three new transiting giant planets, first detected with the WASP telescopes, and establish their planetary nature with follow up spectroscopy and ground-based photometric light curves. WASP-92 is an F7 star, with a moderately inflated planet orbiting with a period of 2.17 d, which has R_p = 1.461 ± 0.077R_J and M_p = 0.805 ± 0.068M_J. WASP-93b orbits its F4 host star every 2.73 d and has R_p = 1.597 ± 0.077R_J and M_p = 1.47 ± 0.029M_J. WASP-118b also has a hot host star (F6) and is moderately inflated, where R_p = 1.440 ± 0.036R_J and M_p = 0.514 ± 0.020M_J and the planet has an orbital period of 4.05 d. They are bright targets (V = 13.18, 10.97 and 11.07, respectively) ideal for further characterization work, particularly WASP-118b, which is being observed by K2 as part of campaign 8. The WASP-93 system has sufficient angular momentum to be tidally migrating outwards if the system is near spin-orbit alignment, which is divergent from the tidal behaviour of the majority of hot Jupiters discovered.
