Dust temperature radial profile of the MC at the reference snapshot. The light blue (dark blue) line shows the median of the mass- weighted (luminosity-weighted) dust temperatures in spherical shells; the corresponding shaded areas bracket the 16th–84th percentiles. Vertical dotted lines mark the positions of massive (m_⋆ ≥ 40 M_⊙) stars. As a reference, we show the temperature profile for the S20 model in the homogeneous case (green line) and in the radiation pressure case (magenta line).
