Abstract

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 lightcurves. WASP-92 is an F7 star, with a moderately inflated planet orbiting with a period of 2.17 days, 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 days 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 Mp = 0.513 ± 0.041M_J and the planet has an orbital period of 4.05 days. They are bright targets (V = 13.18, 10.97 and 11.07 respectively) ideal for further characterisation work, particularly WASP-118b, which is being observed by K2 as part of campaign 8. WASP-93b is expected to be tidally migrating outwards, which is divergent from the tidal behaviour of the majority of hot Jupiters discovered.
