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 ( $M_{P} = 0.28 M_{J}$ ) object with a radius of $1.11 R_{J}$ orbiting a G4 star with a period of $4.6$ d. WASP-160Bb has a mass and radius ( $M_{p} = 0.28 M_{J}$ , $R_{p} = 1.09 R_{J}$ ) 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 ( $M_{P} = 2.13 M_{J}$ , $R_{p} = 1.13 R_{J}$ ) hot Jupiter, orbiting a G2 star on a close-in ( $P = 1.8$ d), but tidally stable orbit. WASP-165b is a classical ( $M_{p} = 0.66 M_{J}$ , $R_{P} = 1.26 R_{J}$ ) 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.
