Two-dimensional dust temperatures in the envelope-only models (left column) and in the envelope-plus-disk models (middle column). The white contours show the location in which the temperature is 70 K as an indication of the approximate temperature at which methanol is sublimated at the densities of the models. The right column compares the mid-plane temperature in the envelope-plus-disk models and the envelope-only models. The first row presents the fiducial model, and the second row presents the fiducial model with high mm opacity dust grains. In all figures in this work, κ_dust refers to the opacity of the dust grains at mm wavelengths. On average, the temperatures are lower when a disk is present and when grains have high mm opacity.
