Caption: Figure 15.

The observed flux of Betelgeuse by Fay & Johnson (1973) (dashed blue line) slightly matched the fitting reddened spectrum considering the RAT-D mechanism (solid red line) within confidence intervals of 1σ for each parameter (red shaded region) in the left panel. The right panel is the grain disruption size given by the grain parameters from the best-fit model.
