Abstract (from CDS):

We report the discovery of TOI-677 b, first identified as a candidate in light curves obtained within Sectors 9 and 10 of the Transiting Exoplanet Survey Satellite (TESS) mission and confirmed with radial velocities. TOI-677 b has a mass of Mp = 1.236–0.067+0.069MJ, a radius of RP = 1.170±0.03RJ, and orbits its bright host star (V = 9.8 mag) with an orbital period of 11.23660±0.00011 d, on an eccentric orbit with e=0.435±0.024. The host star has a mass of M* = 1.181±0.058M☉, a radius of R* = 1.28–0.03+0.03R☉, an age of 2.92–0.73+0.80 Gyr and solar metallicity, properties consistent with a main-sequence late-F star with Teff=6295±77 K. We find evidence in the radial velocity measurements of a secondary long-term signal, which could be due to an outer companion. The TOI-677 b system is a well-suited target for Rossiter-Mclaughlin observations that can constrain migration mechanisms of close-in giant planets.
