Effect of the gas temperature on the equilibrium solution by varying the radial profile T(r). The "optically thick" case (gray) and the "optically thin" case (black) correspond to the gas temperature profiles displayed in Fig. D.4. The optically thin case corresponds to the gas temperature profile used for the fiducial model described in Sect. 5. 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, f_dg = 10⁻², and α_hydro = 10⁻⁴. Panels (a)-(f) show the same key quantities as in Fig. 7.
