摘要：We present the discovery of three new transiting hot Jupiters by the WASP-South project, WASP-161b, WASP-163b, and WASP-170b. Follow-up radial velocities obtained with the Euler/CORALIE spectrograph and transit light curves obtained with the TRAPPIST-North, TRAPPIST-South, SPECULOOS-South, NITES, and Euler telescopes have enabled us to determine the masses and radii for these transiting exoplanets. WASP-161b completes an orbit around its V=11.1 F6V-type host star in 5.406 days, and has a mass M p =2.5±0.2M Jup and radius R p =1.14±0.06 R Jup . WASP-163b orbits around its host star (spectral type G8V and the magnitude V= 12.5) every 1.609 days, and has a mass of M P =1.9±0.2 M Jup and a radius of R p =1.2±0.1 R Jup . WASP-170 b has a mass of 1.7±0.2 M Jup and a radius of 1.14±0.09 R Jup and is on a 2.344 day orbit around a G1V-type star of magnitude V=12.8. Given their irradiations (∼10 9 erg s −1 cm −2 ) and masses, the three new planets’ sizes are in good agreement with classical models of irradiated giant planets.
