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.
