Two Earth-size Planets and an Earth-size Candidate Transiting the nearby Star HD 101581

Two Earth-size Planets and an Earth-size Candidate Transiting the nearby Star HD 101581

We report the validation of multiple planets transiting the nearby ( d = 12.8 pc) K5V dwarf HD 101581 (GJ 435, TOI–6276, TIC 397362481). This system consists of at least two Earth-size planets whose orbits are near a mutual 4:3 mean-motion resonance, HD 101581 b ( ${R}_{p}={0.956}_{-0.061}^{+0.063}\...
