Discovery of Interstellar Hydrogen Fluoride
David A. Neufeld, Jonas Zmuidzinas, Peter Schilke +1
We report the first detection of interstellar hydrogen fluoride. Using the Long Wavelength Spectrometer (LWS) of the Infrared Space Observatory (ISO), we have detected the 121.6973…
Models for Dense Molecular Cloud Cores
S. D. Doty, D. A. Neufeld
We present a detailed model for the thermal balance, chemistry, and radiative transfer within quiescent dense molecular cloud cores that contain a central protostar. Large variatio…
Molecular Hydrogen in Diffuse Interstellar Clouds of Arbitrary Three-Dimensional Geometry
Marco Spaans, David A. Neufeld
We have constructed three-dimensional models for the equilibrium abundance of molecular hydrogen within diffuse interstellar clouds of arbitrary geometry that are illuminated by ul…
The Wardle Instability in Interstellar Shocks: II. Gas Temperature and Line Emission
David A. Neufeld, James M. Stone
We have modeled the gas temperature structure in unstable C-type shocks and obtained predictions for the resultant CO and H2 rotational line emissions, using numerical simulations…
