Description
We report the discovery of WASP-190b, an exoplanet on a 5.37 day orbit around a mildly evolved F6 IV-V star with V=11.7, T_eff_=6400+/-100 K, M_*_=1.35+/-0.05 M_{sun}_, and R_*_=1.6+/-0.1 R_{sun}_. The planet has a radius of R_P_=1.15+/-0.09 R_Jup_ and a mass of M_P_=1.0+/-0.1 M_Jup_, making it a mildly inflated hot Jupiter. It is the first hot Jupiter confirmed via Doppler tomography with an orbital period of >5 days. The orbit is also marginally misaligned with respect to the stellar rotation, with {lambda}=21{deg}+/-6{deg} measured using Doppler tomography.
