Figure 4.
Same as Fig. 2 but for various grain radii and material properties. Only the boundary for fin = 0.1 is shown. Upper panel: grain size dependence. The solid and dashed lines refer to a = 0.1 and 1 μm, respectively. Lower panel: dust material dependence. The lines from top to bottom refer to AC, graphite, silicate, SNdest and SNcon, respectively.
