Density cross-section of one of the full radiative transfer models. Both panels show the same model, but the right panel is zoomed in relative to the left. The model has parameters M_disk = 0.1 M_⊙, M_env = 1 M_⊙, p = 1.5, = 20◦, and L_input = 12.9 L_⊙. The figure also shows the positions of the CO ice lines at 28 K for the full model, as well as for the equivalent models that do not include the disk and/or outflow.
