WASP-54b, WASP-56b and WASP-57b: Three new sub-Jupiter mass planets from SuperWASP

We present three newly discovered sub-Jupiter mass planets from the SuperWASP survey: WASP-54b is a heavily bloated planet of mass 0.636\(^{+0.025}_{-0.024}\) \mj and radius 1.653\(^{+0.090}_{-0.083}\) \rj. It orbits a F9 star, evolving off the main sequence, every 3.69 days. Our MCMC fit of the sys...
