Formation of Interstellar Ices Behind shock Waves
Edwin A. Bergin, David A. Neufeld, Gary J. Melnick
We have used a coupled dynamical and chemical model to examine the chemical changes induced by the passage of an interstellar shock in well shielded regions. Using this model we de…
The Ionization Fraction in Dense Molecular Gas II: Massive Cores
Edwin A. Bergin, Rene Plume, Jonathan P. Williams +1
We present an observational and theoretical study of the ionization fraction in several massive cores located in regions that are currently forming stellar clusters. Maps of the em…
The Post-Shock Chemical Lifetimes of Outflow Tracers and a Possible New Mechanism to Produce Water Ice Mantles
Edwin A. Bergin, Gary J. Melnick, David A. Neufeld
We have used a coupled time-dependent chemical and dynamical model to investigate the lifetime of the chemical legacy left in the wake of C-type shocks. We concentrate this study o…
