The host star has a mass of 1.22±0.04M, radius of 1.24±0.05R, effective temperature 6158±80K, and metallicity [Fe/H]=+0.17±0.08. The planetary companion has a mass of 4.193±0.094MJ and radius of 1.289±0.066RJ, yielding a mean density of 2.42±0.35g/cm3. Comparing these observed characteristics with recent theoretical models, we find that HAT-P-16b is consistent with a 1Gyr 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. Description: To confirm the transit signal and obtain high-precision light curves for modeling the system, we conducted photometric follow-up observations with the KeplerCam CCD on the FLWO 1.2m telescope. We observed four transit events of HAT-P-16 on the nights of 2009 September 10 and 21, October 19 and 30.
