On the formation of current sheets in response to the compression or expansion of a potential magnetic field
D. I. Pontin, Y. -M. Huang
The compression or expansion of a magnetic field that is initially potential is considered. It was recently suggested by Janse & Low [2009, ApJ, 690, 1089] that, following the volu…
Effects of Line-tying on Magnetohydrodynamic Instabilities and Current Sheet Formation
Yi-Min Huang, A. Bhattacharjee, Ellen G. Zweibel
An overview of some recent progress on magnetohydrodynamic stability and current sheet formation in a line-tied system is given. Key results on the linear stability of the ideal in…
Violation of Richardson's Criterion via Introduction of a Magnetic Field
Daniel Lecoanet, Ellen G. Zweibel, Richard H. D. Townsend +1
Shear flow instabilities can profoundly affect the diffusion of momentum in jets, stars, and disks. The Richardson criterion gives a sufficient condition for instability of a shear…
Do Potential Fields Develop Current Sheets Under Simple Compression or Expansion?
Yi-Min Huang, A. Bhattacharjee, Ellen G. Zweibel
The recent demonstration of current singularity formation by Low et al. assumes that potential fields will remain potential under simple expansion or compression (Low 2006, 2007; J…
Effects of Line-tying on Resistive Tearing Instability in Slab Geometry
Yi-Min Huang, Ellen G. Zweibel
The effects of line-tying on resistive tearing instability in slab geometry is studied within the framework of reduced magnetohydrodynamics (RMHD).\citep{KadomtsevP1974,Strauss1976…
Evolution of Unmagnetized and Magnetized Shear Layers
M. L. Palotti, F. Heitsch, E. G. Zweibel +1
We present numerical simulations of the growth and saturation of the Kelvin-Helmholtz instability in a compressible fluid layer with and without a weak magnetic field. In the absen…
