Evolution of disk properties over time. Azimuthally averaged gas surface densities, dust surface densities, gas temperatures, maximum dust grain radii, vertically integrated gas pressures, and Stokes numbers for the disk are shown in (a)–(f), respectively. The black line in panel (a) outlines the GI-suppressed dead zone in the inner disk as defined by α_GI < 5 × 10⁻³. The black line in panel (c) marks radii in the disk where temperatures fall below the CMB floor at z = 17, about 49 K.
