Abstract

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,  = 6400 ± 100 K, M* = 1.35 ± 0.05 M?, and R* = 1.6 ± 0.1 R?. The planet has a radius of RP = 1.15 ± 0.09 RJup and a mass of MP = 1.0 ± 0.1 MJup, 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 ? = 21° ± 6° measured using Doppler tomography.
