Case of a disk containing a dead zone and with U_f = 10 m s⁻¹ everywhere and Z = Z_⊙. Each panel displays the surface density as a function of distance for different types of material. The thick black line stands for H-He gas surface density. Solid and dashed lines respectively stand for the solid and vapor form of the different species. The red line is for silicates, deep blue for H₂O, light blue for CO, yellow for refractory minerals, and green for iron (see legend below figure). The black dashed line plots the Stokes number (right-hand scale).
