Abstract (from CDS):

We present the discovery of WASP-39b, a highly inflated transiting Saturn-mass planet orbiting a late G-type dwarf star with a period of 4.055259±0.000008d, Transit Epoch T0=2455342.9688±0.0002(HJD), of duration 0.1168±0.0008d. A combined analysis of the WASP photometry, high-precision follow-up transit photometry, and radial velocities yield a planetary mass of Mpl=0.28±0.03MJ and a radius of Rpl=1.27±0.04RJ, resulting in a mean density of 0.14±0.02ρJ. The stellar parameters are mass M*=0.93±0.03M☉, radius R*=0.895±0.23R☉, and age 9+3–4Gyr. Only WASP-17b and WASP-31b have lower densities than WASP-39b, although they are slightly more massive and highly irradiated planets. From our spectral analysis, the metallicity of WASP-39 is measured to be [Fe/H]=-0.12±0.1dex, and we find the planet to have an equilibrium temperature of 1116+33–32K. Both values strengthen the observed empirical correlation between these parameters and the planetary radius for the known transiting Saturn-mass planets.
