Fig. 1
Absorption, scattering, and extinction cross-sections (Cabs, top left; Csca, top right; Cext, bottom left), and albedo Λ (bottom right) of porous dust grains. The quantities are averaged based on the distribution of the particle radii, which follows a power law of dn ∝ a-3.5 da with a ∈ [5,250]nm. The material is astronomical silicate.
