H II regions and CO clouds - The blister model
F. P. Israel;
AaA, 1978, 70, 769

ABSTRACT:A comparison of H II region and CO cloud observations shows that the majority of H II regions are located at the edges of molecular clouds, and have structure suggestive of ionization fronts surrounded by less dense envelopes. The bulk of the ionized material streams away from the associated molecular cloud. The general applicability of this blister model has important consequences for models of both H II region evolution and star formation.
