Abstract

Aims.We study the expansion of the ionization and dissociation fronts (DFs) in a radially stratified molecular cloud, whose density distribution is represented as . We focus on cases with , when the ionization front is “trapped” in the cloud and expands with the preceding shock front. The simultaneous evolution of the outer photodissociation region (PDR) is examined in detail.
