Minimum Dissipative Relaxed States Applied to Laboratory and Space Plasmas
Dastgeer Shaikh, B. Dasgupta, Q. Hu +1
The usual theory of plasma relaxation, based on the selective decay of magnetic energy over the (global) magnetic helicity, predicts a force-free state for a plasma. Such a force-f…
Self-consistent interaction of neutrals and shocks in the local interstellar medium
Dastgeer Shaikh, G. P. Zank, N. Pogorelov
The problem of hydrogen neutrals interacting with the heliospheric bow shock region has received considerable attention recently, motivated primarily by the hope that the Voyager s…
Non Kolmogorov-like Turbulence in the Local Interstellar Medium
Dastgeer Shaikh
We develop a self-consistent model of turbulence in a local interstellar medium (ISM). The model describes a partially ionized magnetofluid ISM in which a neutral hydrogen fluid in…
Passive Convection of Density Fluctuations in the Local Interstellar Medium
Dastgeer Shaikh, G. P. Zank
We have developed a time-dependent three-dimensional model of isotropic, adiabatic, and compressible magnetohydrodynamic plasma to understand nonlinear cascades of density fluctuat…
