Abstract (from CDS):

We report high-precision transit photometry for the recently detected planet HD17156b. Using these new data with previously published transit photometry and radial velocity measurements, we perform a combined analysis based on a Markov Chain Monte Carlo approach. The resulting mass Mp=3.09+0.22–0.17MJup and radius Rp=1.23+0.17–0.20RJup for the planet places it at the outer edge of the density distribution of known transiting planets with ρp=1.66+1.37–0.60ρJup. The obtained transit ephemeris is TTr=2454438.48271+0.00077–0.00057+Nx21.21747+0.00070–0.00067BJD. The derived plausible tidal circularization time scales for HD17156b are larger than the age of the host star. The measured high orbital eccentricity e=0.6719+0.0052–0.0063 can thus not be interpreted as the clear sign of the presence of another body in the system.
