Abstract
We contest the ability of the interstellar dust Hotspot Model to expla in the observed IR emission at short wavelengths of the ISM (interstel lar medium). We show that both the theoretical and experimental bases of the model are not firm, and we perform a molecular dynamics calcula tion of the time needed for the energy of an absorbed photon to spread out in weakly bound HAC (hydrogenated amorphous carbon) solids that c ontradicts the prediction of the Hotspot Model.
