Abstract (from CDS):

We report the discovery of a planet transiting a moderately faint (V = 12.3 mag) late F star, with an orbital period of 3.92289±0.00004 days. From the transit light curve and radial velocity measurements, we determine that the radius of the planet is Rp= 1.40±0.06 RJup and that the mass is Mp= 0.78±0.09 MJup. The density of the new planet, ρ_ p_= 0.35±0.06 g/cm3, fits to the low-density tail of the currently known transiting planets. We find that the center of transit is at Tc = 2454417.9077±0.0003 (HJD), and the total transit duration is 0.143 ± 0.004 days. The host star has M{*}= 1.28±0.13 M and R{*} = 1.32±0.07 R.
