Characterizing K2 Candidate Planetary Systems Orbiting Low-mass Stars. III. A High Mass and Low Envelope Fraction for the Warm Neptune K2-55b
K2-55b is a Neptune-sized planet orbiting a K7 dwarf with a radius of 0.715[subscript -0.040][superscript +0.043]R[subscript ⊙], a mass of 0.688 ± 0.069 M[subscript ⊙], and an effective temperature of 4300[subscript -100][superscript +107] K. Having characterized the host star using near-infrared sp...
