[en] We report the discovery of WASP-190b, an exoplanet on a 5.37-day orbit around an inflated F6 IV-V star with T_eff = 6400 $\pm$ 100 K, M$_{*}$ = 1.35 $\pm$ 0.05 M_sun and R$_{*}$ = 1.6 $\pm$ 0.1 R_sun. The planet has a radius of R_p = 1.15 $\pm$ 0.09 R_Jup and a mass of M_p = 1.0 $\pm$ 0.1 M_Jup, making it a mildly inflated hot Jupiter. The orbit is also marginally misaligned with respect to the stellar rotation, with $\lambda$ = 21 $\pm$ 6$^{\circ}$ measured using Doppler tomography. We compare a Rossiter-McLaughlin analysis (involving radial velocity measurements) with the Doppler tomography method, and find that the latter provides a better constraint on $vsini_{*}$ and $\lambda$.
