Ir Dust Emission, Hii Regions, M17-Sw

Scientific paper

We present the results of models for the infrared dust emission observed in the M17-SW HII region by the ISO Short Wavelength Spectrometer. We interpret the observed spectra in terms of the thermal emission from amorphous carbon and silicate grains, and from Mg-rich crystalline olivine silicates. We estimate that of the order of a few percent of the silicate grain mass in the HII region could be crystalline. Stochastically heated small carbon particles must also be present, in order to explain the short wavelength emission, and we find that in the HII region there is an underabundance of the unidentified infrared band carriers (or PAHs), compared to the adjacent photo-dissociation region.
