Submillimetre emission and the dust content of compact H II regions

We present submillimetre continuum observations of six compact H II regions, most of which have been observed for the first time. These measurements fill the remaining gap between the IRAS observations and millimetre data and more fully define the energy distribution of the thermal dust emission in these objects. New models of compact H II regions are described in which photo-ionization models of the nebula are calculated self-consistently with the solution of the radiative transfer equation for the associated dust. These models are applied to the most well-studied object we observed, G45.13+0.14A. (author)
