Abstract (from CDS):

We report the discovery of WASP-34b, a sub-Jupiter-mass exoplanet transiting its 10.4-magnitude solar-type host star (1SWASPJ110135.89-235138.4; TYC 6636-540-1) every 4.3177 days in a slightly eccentric orbit (e=0.038±0.012). We find a planetary mass of 0.59±0.01M_Jup 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 γ0.45M_Jup at a distance of γ1.2AU from the host star. This third-body is either a low-mass star, a white dwarf, or another planet. The transit depth ((R_P/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%.
