Boundaries of disk conditions and pebble accretion modes in the case of Fig. 2d. The Stokes-Epstein (brown dashed line) and 2D−3D (black dotted line) boundaries are common also in other panels in Fig. 2. The boundary of viscously heated and irradiation heated regimes (magenta solid line), snow line (blue dashed line), and τ_s = 1 line (green dashed line) depend on the disk mass accretion rate, dM_∗/ dt. The left side is characterized by a viscous, 2D accretion, Stokes and high τ_s regime, while the right side is characterized by a irradiation, 3D, Epstein and lower τ_s regime.
