Fig. 8.
Opacity values for three selected wavelengths for mixtures of crystalline and amorphous silicate dust at θ = 100 K. Solid lines are for our forsterite, dashed lines for enstatite. Upper panel: the total mass-normalized cross section is plotted over the fraction of MgSiO3 glass (Boudet et al. 2005) in composite particles with crystalline grains. Lower panel: we plot the dependence on the admixture of crystalline dust, given in multiples of the amount of glassy material.
