Dust temperature distribution for both astronomical silicates and icy silicates for selected grain sizes around ϵ Eri. The chaotic zone of the putative ϵ Eri b is marked as the hashed area. The two light gray areas represent the two distinct dust belts (asteroid belt (A.B.) and outer warm belt) that are consistent with the presence of ϵ Eri b (see Section 5.3 for details). The dark gray area marks the Kuiper-belt-like planetesimal belt (P.B.).
