TOI-6695: A Pair of Near-resonant Massive Planets Observed with TESS from the WINE Survey*
Abstract We present the discovery and characterization of a pair of warm Jovian-mass exoplanets orbiting the Sun-like star TOI-6695, based on Transiting Exoplanet Survey Satellite (TESS) transits and precise radial velocity (RV) measurements obtained with FEROS, HARPS, CHIRON, CORALIE, and PFS. The transiting exoplanet TOI-6695b has an orbital period of ∼80.4 days, a radius of 0.85 R jup , and a mass of 0.21 M jup . The outer planet has a minimum mass of 1.45 M jup and an orbital period of about 242.4 days, confidently constrained by the Doppler time-series data. The TOI-6695 exoplanet system exhibits transit-timing variations due to the dynamical interaction of the planets, which reside near a 3:1 mean-motion resonance. We modeled the TOI-6695 system’s orbital and dynamical configuration by performing self-consistent N -body fits of TESS photometry, ground-based photometry from Observatoire Moana, and precise RV data, all of which are consistent with the presence of a warm Jovian-mass duo of exoplanets.
