Accretion rates within the individual layers, as a function of radius, for the fiducial model described in Sect. 5. The overall steady-state inward accretion rate, Ṁ_acc, is defined as Ṁ_acc = Ṁ_{acc, MRI} + Ṁ_{acc, AD} + Ṁ_{acc, DZ}, where Ṁ_{acc, MRI}, Ṁ_{acc, AD}, and Ṁ_{acc, DZ} correspond to the radially variable accretion rates within the MRI-active layer, zombie zone, and dead zone, respectively. They were computed using the formula provided in Appendix B of Mohanty et al. (2018). The dashed black line corresponds to Ṁ_acc ≈ 3.7 × 10⁻⁹ M_⊙.yr⁻¹, obtained forthe fiducial protoplanetary disk model.
