Cumulative distributions of final orbital configuration. Panel a: period ratio of adjacent pair (P_out ∕P_in), in which vertical lines indicate locations of first-order mean-motion resonances (MMRs). Panel b: mass ratio M_out ∕M_in. Panel c: planetary mass distribution. Black solid lines in each panel represent observed distributions of close-in super-Earths. Red, green, and blue lines indicate results for model1, model3, and model4 in MRI-active disks, respectively. Black dashed line in panel b: result of Ogihara et al. (2015a) for a power-law disk based on the MMSN. Panels d–f are same as panels a–c but for MRI-inactive disks. Red, green, and blue lines in panels d–f indicate results for model2, model5, andmodel6, respectively.
