Reexamination of Induction Heating of Primitive Bodies in Protoplanetary Disks
Raymond L. Menzel, Wayne G. Roberge
We reexamine the unipolar induction mechanism for heating asteroids originally proposed in a classic series of papers by Sonett and collaborators. As originally conceived, inductio…
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…
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…
Multifluid, Magnetohydrodynamic Shock Waves with Grain Dynamics II. Dust and the Critical Speed for C Shocks
Glenn E. Ciolek, Wayne G. Roberge, Telemachos Ch. Mouschovias
This is the second in a series of papers on the effects of dust on multifluid, MHD shock waves in weakly ionized molecular gas. We investigate the influence of dust on the critical…
Time-Dependent, Multifluid, Magnetohydrodynamic Shock Waves with Grain Dynamics I. Formulation and Numerical Tests
Glenn E. Ciolek, Wayne G. Roberge
This is the first in a series of papers on the effects of dust on the formation, propagation, and structure of nonlinear MHD waves and MHD shocks in weakly-ionized plasmas. We mode…
Davis-Greenstein alignment of oblate spheroidal grains
W. G. Roberge, A. Lazarian
We present extensive calculations on the efficiency of grain alignment by the Davis-Greenstein mechanism. We model the grains as oblate spheroids with arbitrary axis ratios. Our de…
