Temperature structure of models with different parameters. The left column presents the envelope-only models, the middle column shows the envelope-plus-disk models, and the right column presents the comparison of a temperature cut at z = 0 au between the two models. The rows from top to bottom show the fiducial model, the model with high mm opacity dust, with a protostellar luminosity of 5 × 10³ L_⊙, with an envelope mass of 800 M_⊙, and finally, the fiducial model with a disk radius of 2000 au.
