We find a planetary mass of 0.59±0.01MJup and radius of 1.22+0.11-0.08R_Jup. There is a linear trend in the radial velocities of 55±4m/s/y indicating the presence of a long-period third body in the system with a mass >0.45MJup at a distance of >1.2AU from the host star. This third-body is either a low-mass star, white dwarf, or another planet. The transit depth ((RP/R*)2=0.0126) and high impact parameter (b=0.90) suggest that this could be the first known transiting exoplanet expected to undergo grazing transits, but with a confidence of only ∼80%. Description: File table1 contains the Radial velocity and line bisector span measurements of WASP-34 obtained using the CORALIE spectrograph. Files euler1.dat and euler2.dat contain the RG band transit photometry obtained using the Euler Telescopes observed on 2010 March 3 and 2010 April 12, respectively.
