Temperature structure of the fiducial envelope-only and envelope-plus-disk. The top row shows the models with low mm opacity dust (κ_{1 mm} ≃ 0.2 cm² g⁻¹), and the bottom row shows models with high mm opacity dust (κ_{1 mm} ≃ 18 cm² g⁻¹). The right column shows a temperature cut for the various models at z = 0 au. The white contours show where the temperature is 68 K (roughly where methanol sublimates from the grains). The black contours show the approximate position of the disk.
