Molecular Line Emission from Multifluid Shock Waves. I. Numerical Methods and Benchmark Tests

Glenn E. Ciolek, Wayne G. Roberge

We describe a numerical scheme for studying time-dependent, multifluid, magnetohydrodynamic shock waves in weakly ionized interstellar clouds and cores. Shocks are modeled as propa…

Hydromagnetic Waves in Weakly Ionised Media. I. Basic Theory, and Application to Interstellar Molecular Clouds

Telemachos Ch. Mouschovias, Glenn E. Ciolek, S. A. Morton

We present a comprehensive study of MHD waves and instabilities in a weakly ionised system, e.g., an interstellar molecular cloud. We determine all the critical wavelengths of pert…

Magnetically-Regulated Fragmentation Induced by Nonlinear Flows and Ambipolar Diffusion

Shantanu Basu, Glenn E. Ciolek, Wolf Dapp +1

We present a parameter study of simulations of fragmentation regulated by gravity, magnetic fields, ambipolar diffusion, and nonlinear flows. The thin-sheet approximation is employ…

Nonlinear Evolution of Gravitational Fragmentation Regulated by Magnetic Fields and Ambipolar Diffusion

Shantanu Basu, Glenn E. Ciolek, James Wurster

We present results from an extensive set of simulations of gravitational fragmentation in the presence of magnetic fields and ambipolar diffusion. The average fragmentation spacing…

Driven waves in a two-fluid plasma

W. G. Roberge, Glenn E. Ciolek

We study the physics of wave propagation in a weakly ionised plasma, as it applies to the formation of multifluid, MHD shock waves. We model the plasma as separate charged and neut…

Formation and Collapse of Nonaxisymmetric Protostellar Cores in Planar Magnetic Interstellar Clouds: Formulation of the Problem and Linear Analysis

Glenn E. Ciolek, Shantanu Basu

We formulate the problem of the formation and collapse of nonaxisymmetric protostellar cores in weakly ionized, self-gravitating, magnetic molecular clouds. In our formulation, mol…
