WASP-190b: Tomographic discovery of a transiting hot Jupiter

Earth and Planetary Astrophysics 2019-03-20 v2

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, 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. It is the first hot Jupiter confirmed via Doppler tomography with an orbital period >5 days. The orbit is also marginally misaligned with respect to the stellar rotation, with λ\lambda = 21 ±\pm 6^{\circ} measured using Doppler tomography.
