TrES-4b RV and Ic curves
Listed in IVOA Registry (Virtual Observatory)
We update the TrES-4 system parameters using high-precision HARPS-N radial-velocity measurements and new photometric light curves.
Description
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 M_p_=0.49+/-0.04M_Jup_, significantly lower than previously reported.
Combined with the large radius (R_p_=1.84_-0.09_^+0.08^R_Jup_) 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.
