Abstract :
[en] 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}[SUB]eff[/SUB]} = 6400 ± 100 K, M [SUB]*[/SUB] = 1.35 ± 0.05 M [SUB]⊙[/SUB], and R [SUB]*[/SUB] = 1.6 ± 0.1 R [SUB]⊙[/SUB]. The planet has a radius of R [SUB]P[/SUB] = 1.15 ± 0.09 R [SUB]Jup[/SUB] and a mass of M [SUB]P[/SUB] = 1.0 ± 0.1 M [SUB]Jup[/SUB], 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 λ = 21° ± 6° measured using Doppler tomography.
