Part II: Formation of Stars and H II Regions
Part of the Lecture Notes in Physics book series (LNP, volume 42)


We compare parameters derived from the observed radio and near-infrared flux densities of a sample of 21 compact H II regions with theoretical parameters calculated for dusty Strömgren spheres. Preliminary results of this comparison suggest that the dust inside compact H II regions is quite often depleted by large factors, consistent with evaporation of the mantle material of core-mantle particles.
