Abstract:
We present three newly discovered sub-Jupiter mass planets from the
SuperWASP survey: WASP-54b is a heavily bloated planet, and orbits a
F9 star, evolving off the main sequence, every 3.69 days. WASP-56b and
WASP-57b orbit main sequence stars of spectral type G6 every 4.67 and
2.84 days, respectively. WASP-56b and WASP-57b show no radius anomaly
and a high density implying a large core of heavy elements; possibly
as high as 50MEarth in the case of WASP-57b. We present the Radial
Velocity and line bisector span measurements for the transiting planet
host stars WASP-54, WASP-56 and WASP-57.
