Updated Mass, Eccentricity, and Tidal Heating Constraints for the Earth-sized Planet LP 791-18 d

LP 791-18 d is a temperate Earth-sized planet ( R _P = 1.03 R _⊕ , P = 2.76 days) orbiting a late M dwarf, with an interior super-Earth (LP 791-18 b, R _P = 1.2 R _⊕ , P = 0.95 days) and an exterior sub-Neptune (LP 791-18 c, R _P = 2.5 R _⊕ , P = 4.99 days). Dynamical interactions between LP 791-18...
