Left: dust temperature structure of the fiducial model. Overlaid on this plot (and the middle plot) are contours for the plotted temperatures, and extinction contours for vertical A_V = 1 and A_V = 10. Middle: gas temperature structure of the fiducial model. Right: CO ice line. We follow the ice line definition of Antonellini (2016), with the ice line being defined as where the gas and ice abundances are equal. Dust temperature contours are marked at 15, 20, and 25 K.
