Descripción
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 Rp = 1.461 ±
0.077RJ and Mp = 0.805 ±
0.068MJ. WASP-93b orbits its F4 host star every 2.73 d 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 = 0.514 ± 0.020MJ
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.
