Comparison between our model results and the laboratory-measured properties of some real dust species, as listed in Table 5, for the model parameters that provide meaningful constraints on the dust composition. Left: constraints on the parameters that describe the temperature dependence of dust sublimation. The dashed diagonal axis shows how J_{1700 K} (the sublimation rate of dust at 1700 K) varies with and ℬ′. Right: combined constraints on k₁ (the imaginary part of the complex refractive index for λ< 8μm) and the 1700 K sublimation rate. Note that the sublimation rate decreases to the right.
