Fig. 3


Equilibrium grain temperature of an 70% ice and 30% astronomical silicate composition depending on grain size s and distance to the star r. The results for the 50% ice – 50% silicate mixture are similar. The wavy shape of the isotherms is caused by the dependence of the absorption efficiency on the grain size (as explained in Krivov et al. 2008, see their Figs. 2 and 6).
