The Transition from Atomic to Molecular Hydrogen in Interstellar Clouds: 21 cm Signature of the Evolution of Cold Atomic Hydrogen in Dense Clouds
ASTROPHYSICAL JOURNAL, no. 1 (2007): 273-289
Abstract
We have investigated the timescale for formation of molecular clouds by examining the conversion of H I to H-2 using a time-dependent model with H-2 photodissociation including self-shielding. H-2 formation on dust grains and cosmic-ray destruction are also included in one-dimensional model slab clouds that incorporate time-independent de...More
