https://doi.org/10.1007/978-3-662-24975-8Most infrared sources found at λ < 40μ and associated with HII regions appear to fall into one of three classes which may be loosely referred to as the reddened 0 stars, the compact HII regions and the protostellar objects. However recent observations indicate that the distinction between the last two types is blurred.

https://doi.org/10.1007/978-3-662-24974-1A brief account of the techniques used at λ > 40 μm is followed by photometric data, maps of IR regions and spectral data. In particular the He./H. ratio is discussed and new features on maps of W3 and the Galactic Centre are presented.

The early stages of HII regions,A model for W3(A) is described and the results of the calculations for the dynamical evolution of a compact HII region with a dust front are discussed.
