Abstract (from CDS):

We report the discovery of TOI-172 b from the Transiting Exoplanet Survey Satellite (TESS) mission, a massive hot Jupiter transiting a slightly evolved G star with a 9.48-day orbital period. This is the first planet to be confirmed from analysis of only the TESS full frame images, because the host star was not chosen as a two-minute cadence target. From a global analysis of the TESS photometry and follow-up observations carried out by the TESS Follow-up Observing Program Working Group, TOI-172 (TIC 29857954) is a slightly evolved star with an effective temperature of Teff = 5645 ± 50 K, a mass of M* = 1.128–0.061+0.065M☉, radius of R* = 1.777–0.044+0.047R☉, a surface gravity of log g* = 3.993–0.028+0.027, and an age of 7.4–1.5+1.6 Gyr. Its planetary companion (TOI-172 b) has a radius of RP = 0.965–0.029+0.032RJ, a mass of MP = 5.42–0.20+0.22MJ, and is on an eccentric orbit (e=0.3806–0.0090+0.0093). TOI-172 b is one of the few known massive giant planets on a highly eccentric short-period orbit. Future study of the atmosphere of this planet and its system architecture offer opportunities to understand the formation and evolution of similar systems.
