Close to 2:1 mean-motion resonance with EPIC 203771098 b.

Petigura et al.'s estimation of the mass comes from a model with circular orbit. They also use a model with eccentricity as free parameter, which gives a Mass M=31.0±6.4 Mearth and e<0.37 (95%).

Sinukoff et al. compute the equilibrium temperature assuming an albedo of 0.3.
