On large-scale dynamos with stable stratification and the application to stellar radiative zones
Valentin Skoutnev, Jonathan Squire, Amitava Bhattacharjee
Our understanding of large-scale magnetic fields in stellar radiative zones remains fragmented and incomplete. Such magnetic fields, which must be produced by some form of dynamo m…
A heuristic model for MRI turbulent stresses in Hall MHD
M. Lingam, A. Bhattacharjee
Although the Shakura-Sunyaev viscosity prescription has been highly successful in characterizing myriad astrophysical environments, it has proven to be partly inadequate in mod…
Generation of large-scale magnetic fields by small-scale dynamo in shear flows
Jonathan Squire, Amitava Bhattacharjee
We propose a new mechanism for turbulent mean-field dynamo in which the magnetic fluctuations resulting from a small-scale dynamo drive the generation of large-scale magnetic field…
Rapid Change of Field Line Connectivity and Reconnection in Stochastic Magnetic Fields
Yi-Min Huang, A. Bhattacharjee, Allen H. Boozer
Magnetic fields without a direction of continuous symmetry have the generic feature that neighboring field lines exponentiate away from each other and become stochastic, hence the…
Anisotropic MHD Turbulence
C. S. Ng, A. Bhattacharjee
The solar wind and the interstellar medium are permeated by large-scale magnetic fields that render magnetohydrodynamic (MHD) turbulence anisotropic. In the weak-turbulence limit i…
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…
