Direct Evidence for Two-Fluid Effects in Molecular Clouds
David A. Tilley, Dinshaw S. Balsara
We present a combination of theoretical and simulation-based examinations of the role of two-fluid ambipolar drift on molecular line widths. The dissipation provided by ion-neutral…
Dust Settling in Magnetorotationally-Driven Turbulent Discs II: The Pervasiveness of the Streaming Instability and its Consequences
D. A. Tilley, D. S. Balsara, S. D. Brittain +1
We present a series of simulations of turbulent stratified protostellar discs with the goal of characterizing the settling of dust throughout a minimum-mass solar nebula. We compar…
Dust Settling in Magnetorotationally-Driven Turbulent Discs I: Numerical Methods and Evidence for a Vigorous Streaming Instability
Dinshaw S. Balsara, David A. Tilley, Terrence Rettig +1
(Abridged) In this paper we have used the RIEMANN code for computational astrophysics to study the interaction of a realistic distribution of dust grains with gas in a vertically s…
A Two-Fluid Method for Ambipolar Diffusion
David A. Tilley, Dinshaw S. Balsara
We present a semi-implicit method for isothermal two-fluid ion-neutral ambipolar drift that is second-order accurate in space and time. The method has been implemented in the RIEMA…
Simulating Anisotropic Thermal Conduction in Supernova Remnants, Implications for the Interstellar Medium
D. S. Balsara, A. J. Bendinelli, D. A. Tilley +2
We present a large number of two and a half dimensional simulations of supernova remnants expanding into interstellar media having a range of densities, temperatures and magnetic f…
Post-Outburst Observations of V1647 Ori: Detection of a Brief Warm, Molecular Outflow
Sean Brittain, Terrence Rettig, Theodore Simon +4
We present new observations of the fundamental ro-vibrational CO spectrum of V1647 Ori, the young star whose recent outburst illuminated McNeil's Nebula. Previous spectra, acquired…
