摘要：

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 +/- 0.05M(circle dot), and R-* = 1.6 +/- 0.1 R-circle dot. The planet has a radius of R-P = 1.15 +/- 0.09 R-Jup and a mass of M-P = 1.0 +/- 0.1M(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 degrees +/- 6 degrees measured using Doppler tomography.
