DOIAbstract
We present the confirmation of the eccentric warm giant planet TOI-201 b, first identified as a candidate in Transiting Exoplanet Survey Satellite photometry (Sectors 1-8, 10-13, and 27-28) and confirmed using ground-based photometry from Next Generation Transit Survey and radial velocities from FEROS, HARPS, CORALIE, and MINERVA-Australis. TOI-201 b orbits a young ( 0.87+0.46−0.49Gyr ) and bright (V = 9.07 mag) F-type star with a 52.9781 day period. The planet has a mass of 0.42+0.05−0.03MJ , a radius of 1.008+0.012−0.015RJ , and an orbital eccentricity of 0.28+0.06−0.09; it appears to still be undergoing fairly rapid cooling, as expected given the youth of the host star. The star also shows long-term variability in both the radial velocit...
