Results of the modified blackbody fitting for the BWB RQ sample. Top: derived dust grain number (Nd) as a function of dust temperature (Td). Bottom: relationship between bolometric luminosity (Lbol) and Nd. In both panels, colors indicate the assumed dust composition: graphite (cyan), silicates (black), and silicon carbide (orange).
