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±100K, M * =1.35±0.05 M e , and R * =1.6±0.1 R e . 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 >5days. The orbit is also marginally misaligned with respect to the stellar rotation, with λ=21°±6° measured using Doppler tomography.
