Authors:Hay et alAbstract: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 Rp=1.461±0.077RJ and Mp=0.805±0.068MJ. WASP-93b orbits its F4 host star every 2.73 days and has Rp=1.597±0.077RJ and Mp=1.47±0.029MJ. WASP-118b also has a hot host star (F6) and is moderately inflated, where Rp=1.440±0.036RJ and Mp=0.513±0.041MJ 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.
