Temperature jump as a consequence of the equilibrium temperature degeneracy. Panels a and c: temperature maps of the quiescent phase for the models FULL and NOFREQIRR, respectively. The dashed red lines show the radial profiles of the temperatures at a height of z/r = 0.2 (indicated by the dotted white line). The solution of Eq. (G.3) for T_eq at every radius is represented by the blue line. The green contours mark the dust sublimation fronts. Panels b and d: function given in Eq. (13), evaluated at four different radii for both models, respectively. The star-shaped markers indicate which of the available solutions is adopted by the solver at each radius. The same markers were used to locate the respective evaluation radii in panels a and c.
