SEDs of the case of the overabundance of small grains depending on the stellar properties (i.e., blowout sizes). Solid and dashed lines indicate the modeled SED of the dust reemission for the two different disk structures (thin belts and broad disks). The dotted lines represent the direct stellar radiations. The top-left plot shows the result based on the single power law grain size distribution (OS1+UM1+SL1), while the other three plots exhibit the results based on the broken power law grain size distribution, specifically the overabundance of small grains with the different scaling factors, 10, 50, and 100 (i.e., OS10, OS50, and OS100). See Table 4 and Fig. 2 for the proposed grain size distributions depending on the central star and blowout sizes (Thébault & Augereau 2007; Kim et al. 2018).
