Title: H$_3^+$ ABUNDANCES MODELED WITH A VARIABLE COSMIC RAY IONIZATION RATE
Creators: Rimmer, Paul B.; Herbst, Eric
Issue Date: 2008
Abstract: Recent observations of $H_3^+$ abundances in diffuse clouds have suggested a higher value for the cosmic ray ionization than has been generally accepted. We provide a model that takes into account a variable cosmic ray ionization, and show that it produces $H_3^+$ abundances close to the observed values. We also apply this method to an IR-dense cloud model.
