Temperatures (top row) and energy fluxes (bottom row) as a function of time for points 1 and 2. The results are presented for distances of 3 au and 1.24 au in the left column and in the right column, respectively. The illumination functions are shown in Fig. 6. The upper row illustrates the temperature changes at the surface (red curves) and at the lower boundary of the dust layer (blue curves) during one rotation for the two selected points (dashed curves for Point 1 and solid curves for Point 2). The corresponding solar zenith angle is represented by thin dotted curves. The lower row plots the energy flows: total absorbed energy (dotted curves), and heat flux at both the surface (red curves) and the lower boundary of the dust layer (blue curves).
