Abstract

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-161 b 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-163 b 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 _Jupand a radius of 1.14 ± 0.09 R _Jupand is on a 2.344 day orbit around a G1V-type star of magnitude V = 12.8. Given their irradiations (~10⁹ erg s⁻¹ cm⁻²) and masses, the three new planets' sizes are in good agreement with classical models of irradiated giant planets.
