Abstract (from CDS):

We update the TrES-4 system parameters using high-precision HARPS-N radial-velocity measurements and new photometric light curves. A combined spectroscopic and photometric analysis allows us to determine a spectroscopic orbit with a semi-amplitude K=51±3m/s. The derived mass of TrES-4b is found to be Mp=0.49±0.04MJup, significantly lower than previously reported. Combined with the large radius (Rp=1.84–0.09+0.08RJup) inferred from our analysis, TrES-4b becomes the transiting hot Jupiter with the second-lowest density known. We discuss several scenarios to explain the puzzling discrepancy in the mass of TrES-4b in the context of the exotic class of highly inflated transiting giant planets.
