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…
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…
