WASP-147b, 160Bb, 164b and 165b : two hot Saturns and two Jupiters, including two planets with metal-rich hosts

We report the discovery of four transiting hot Jupiters, WASP-147, WASP-160B, WASP-164 and WASP-165 from the WASP survey. WASP-147b is a near Saturn-mass (MP = 0.28MJ) object with a radius of 1.11 RJ orbiting a G4 star with a period of 4.6 d. WASP-160Bb has a mass and radius (Mp = 0.28 MJ, Rp = 1.09 RJ) near-identical to WASP-147b, but is less irradiated, orbiting a metal-rich ([Fe/H]* = 0.27) K0 star with a period of 3.8 d. WASP-160B is part of a near equal-mass visual binary with an on-sky separation of 28.5 arcsec. WASP-164b is a more massive (MP = 2.13 MJ, Rp = 1.13 RJ) hot Jupiter, orbiting a G2 star on a close-in (P = 1.8 d), but tidally stable orbit. WASP-165b is a classical (Mp = 0.66 MJ, RP = 1.26 RJ) hot Jupiter in a 3.5 d period orbit around a metal-rich ([Fe/H]* = 0.33) star. WASP-147b and WASP-160Bb are promising targets for atmospheric characterization through transmission spectroscopy, while WASP-164b presents a good target for emission spectroscopy.
