MCMax models that account for the emission of the star and only the first innermost silicate ring located at 0.8 au and 0.04 au in width. The models differ for the particle size lower limit, dust mass, and carbon percentage. The top plot model accounts for a dust mass of 10⁻⁵ M_⊕ and no carbon; the center plot model accounts for a mass of 1.17 × 10⁻⁴ M_⊕ and no carbon; the bottom plot model accounts for a mass of 3.33 × 10⁻⁴ M_⊕ and 25 % carbon.
