The planetary companion has a mass Mp = 1.80 \\pm 0.17 MJ and radius Rp = 1.16 \\pm 0.07 RJ, yielding a mean density of 1.15 \\pm 0.15 times that of Jupiter. From a spectral analysis and comparisons with stellar models, we find the host star has M* = 0.925 \\pm 0.120 Msun, R* = 1.003 \\pm 0.053 Rsun, Teff = 5800 \\pm 150 K and [Fe/H] = -0.40 \\pm 0.12.
