cds-question@unistra.frexoplanetsdwarf-starsk-starsvisible-astronomyspectroscopyinfrared-photometryWide-band photometryradial-velocityWe report the discovery by the ground-based Hungarian-made Automated Telescope Network (HATNet) survey of the transiting exoplanet HAT-P-68b, which has a mass of 0.724{+/-}0.043M_J_, and radius of 1.072{+/-}0.012R_J_. The planet is in a circular P=2.2984day orbit around a moderately bright V=13.937{+/-}0.030magnitude K-dwarf star of mass 0.673_-0.014_^+0.020^M{sun}, and radius 0.6726{+/-}0.0069R{sun}. The planetary nature of this system is confirmed through follow-up transit photometry obtained with the Fred L. Whipple Observatory (FLWO) 1.2m telescope, high-precision radial velocities measured using Keck I/High Resolution Echelle Spectrometer (HIRES), FLWO 1.5m/Tillinghast Reflector Echelle Spectrograph (TRES), and Observatoire de Haute-Provence (OHP) 1.9m/Sophie, and high-spatial-resolution speckle imaging from WIYN 3.5m/DSSI. HAT-P-68 is at an ecliptic latitude of +3{deg} and outside the field of view of both the NASA Transiting Exoplanet Survey Satellite primary mission and the K2 mission. The large transit depth of 0.036mag (r band) makes HAT-P-68b a promising target for atmospheric characterization via transmission spectroscopy.2021AJ....161...64Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/161/64CatalogResearchIsServedByTAP VizieR generic servicerelated-toI/345 : Gaia DR2 (Gaia Collaboration, 2018)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)J/A+A/428/1001 : Non-linear limb-darkening law LTE models.
