Merged ionization/dissociation fronts in planetary nebulae
William J. Henney, R. J. R. Williams, Gary J. Ferland +2
The hydrogen ionization and dissociation front around an ultraviolet radiation source should merge when the ratio of ionizing photon flux to gas density is sufficiently low and the…
On the enhanced cosmic-ray ionization rate in the diffuse cloud towards Zeta Persei
Gargi Shaw, G. J. Ferland, R. Srianand +3
The spatial distribution of the cosmic-ray flux is important in understanding the Interstellar Medium (ISM) of the Galaxy. This distribution can be analyzed by studying different m…
A PDR-Code Comparison Study
M. Roellig, N. P. Abel, T. Bell +21
We present a comparison between independent computer codes, modeling the physics and chemistry of interstellar photon dominated regions (PDRs). Our goal was to understand the mutua…
