Abstract (from CDS):

We report the discovery of HAT-P-16b, a transiting extrasolar planet orbiting the V = 10.8 mag F8 dwarf GSC 2792-01700, with a period P = 2.775960 ±0.000003 days, transit epoch Tc= 2455027.59293±0.00031 (BJD10), and transit duration 0.1276±0.0013 days. The host star has a mass of 1.22 ±0.04 M☉, radius of 1.24±0.05 R☉, effective temperature 6158±80 K, and metallicity [Fe/H] = +0.17±0.08. The planetary companion has a mass of 4.193±0.094 MJ and radius of 1.289±0.066 RJ, yielding a mean density of 2.42±0.35 g/cm3. Comparing these observed characteristics with recent theoretical models, we find that HAT-P-16b is consistent with a 1 Gyr H/He-dominated gas giant planet. HAT-P-16b resides in a sparsely populated region of the mass-radius diagram and has a non-zero eccentricity of e = 0.036 with a significance of 10σ.
