Radial average temperatures of 100 spherical shells of st28gm06n052. The top panel shows the temperatures as computed with CO⁵BOLD. The bottom panel shows the dust temperatures computed in RADMC-3D with a point source at the centre that approximates the star in st28gm06n052. The middle line of each curve is the average temperature of each shell, the narrow darker field is the temperature’s standard deviation of each shell, and the wide light field show the minimum and maximum temperature of each shell. The plots start at 3 au, which is just below where dust forms at this snapshot (3.4 au). The vertical black dots indicate half the edge length (centre to box edge) of the computation box.
