Notes. The T_eff, log g, metallicity, and mass measurements are taken from Mathur et al. (2017). The rotation periods and Kepler apparent magnitudes are taken from Santos et al. (2019, 2021) while the orbital periods of the confirmed planets are from Morton et al. (2016). The semi-major axis is calculated with the Kepler’s third law, assuming the planetary mass is negligible compared to the stellar mass. The P_orb value was determined in this work for a newly identified, non-transiting object.
