Abstract

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 1.11RJ orbiting a G4 star with a period of 4.6 d. WASP-160Bb has a mass and radius (?Mp=0.28MJ?, Rp=1.09RJ?) 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=2.13MJ?, Rp=1.13RJ?) hot Jupiter, orbiting a G2 star on a close-in (P = 1.8 d), but tidally stable orbit. WASP-165b is a classical (?Mp=0.66MJ?, RP=1.26RJ?) 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.
