Composite Grains: Effects of Porosity and Inclusions on the 10$\mu$m Silicate Feature

Deepak B. Vaidya, Ranjan Gupta

We calculate the absorption efficiency of the composite grains, made up of host silicate spheroids and inclusions of ices/graphites/or voids, in the spectral region $7.0-14.0\mu$m Th…
