Abstract:
We report on three new transiting hot Jupiter planets, discovered from
the WASP surveys, which we combine with radial velocities from
OHP/SOPHIE and Euler/CORALIE and photometry from Euler and TRAPPIST.
The planets WASP-76b, WASP-82b, and WASP-90b are all inflated, with
radii of 1.7-1.8RJup. All three orbit hot stars, of type F5-F7, with
orbits of 1.8-3.9d, and all three stars have evolved,
post-main-sequence radii (1.7-2.2R☉). Thus the three planets fit
a known trend of hot Jupiters that receive high levels of irradiation,
as a result of their being highly inflated. We caution, though, about
the presence of a selection effect, in that non-inflated planets
around ∼2R☉ post-MS stars can often produce transits too shallow
to be detected by the ground-based surveys that have found the
majority of transiting hot Jupiters.
Description:
Radial velocities for three stars (WASP-76, WASP-82 and WASP-90)
obtained with the OHP/SOPHIE and Euler/CORALIE spectrographs, which
reveal the presence of hot Jupiter exoplanets.
