Effect of overall change in the vertically integrated dust-to-gas mass ratio on the equilibrium solution when varying the radially constant parameter f_dg from 10⁻⁵ (99.9 dust depletion relative to standard ISM) to 10⁻¹ (dust-rich disk): The case f_dg = 10⁻⁵ is shown in blue, f_dg = 10⁻⁴ in dark orange, f_dg = 10⁻³ in green, f_dg = 10⁻² in red (fiducial model), and f_dg = 10⁻¹ in purple. The panels show the various steady-state profiles of some key quantities, for the model parameters M_⋆ = 1 M_⊙, L_⋆ = 2 L_⊙, M_disk = 0.05 M_⋆, a_dust =1 μm, and α_hydro = 10⁻⁴. Panels a–f show the same key quantities as in Fig. 7.
