Part III: IR-Sources, Masers and Compact H II Regions
Part of the Lecture Notes in Physics book series (LNP, volume 42)


Most 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.
