Radial structure of snapshot of set-up L3.85T27 for the full modelled region. Shown are the drift model, where ξ^(Fo) = 0.1 (purple), and the PC model, where ξ^(Fo) = 1.0 (orange). From the top left, the 12 panels show: (a) gas velocity u_g, sound speed c_s; (b) gas density ρ_g, dust density 10⁴ × ρ_d (log); (c) drift velocity v_D; (d) true degree of condensation of silicon and magnesium ; (e) net growth rate , net decay rate , and non-thermal sputtering (log) times n_d,FodV (where dV is the cell volume); (f) average grain radius r_d; (g) Eddington factor f_Edd; (h) extinction coefficient χ_H, Rosseland mean extinction coefficient χ_R; (i) gas temperature T_g, radiative temperature T_r, and dust temperature T_d; (j) gas opacity κ_H and Rosseland mean opacity κ_R (log); (k) temperature ratios T_d/T_r and (T_g/T_r)_eq; and (l) dust-to-gas density ratio δ_dg. All properties are drawn vs the stellar radius R_* (lower axis) and astronomical units (AU; upper axis). The grey horizontal lines are guides.
