Dynamics of Alfvén waves in partially ionized astrophysical plasmas
Dastgeer Shaikh
We develop a two dimensional, self-consistent, compressible fluid model to study evolution of Alfvenic modes in partially ionized astrophysical and space plasmas. The partially ion…
3D Hall MHD Modeling of Solar Wind Plasma Spectra
Dastgeer Shaikh, G. P. Zank
We present fully self consistent 3D simulations of compressible Hall MHD plasma that describe spectral features relevant to the solar wind plasma. We find that a spectru…
Whistler Wave Turbulence in Solar Wind Plasma
Dastgeer Shaikh, G. P. Zank
Whistler waves are present in solar wind plasma. These waves possess characteristic turbulent fluctuations that are characterized typically by the frequency and length scales that…
Self-consistent Simulations of Plasma-Neutral in a Partially Ionized Astrophysical Turbulent Plasma
Dastgeer Shaikh, G. P. Zank
A local turbulence model is developed to study energy cascades in the heliosheath and outer heliosphere (OH) based on self-consistent two-dimensional fluid simulations. The model d…
Turbulent Density Spectrum in Solar Wind Plasma
Dastgeer Shaikh, G. P. Zank
The density fluctuation spectrum in the solar wind reveals a Kolmogorov-like scaling with a spectral slope of -5/3 in wavenumber space. The energy transfer process in the magnetize…
Spectral features of solar wind turbulent plasma
Dastgeer Shaikh, G. P. Zank
Spectral properties of a fully compressible solar wind Hall Magnetohydrodynamic plasma are investigated by means of time dependent three dimensional Hall MHD simulations. Our simul…
Turbulent Spectra in the Solar Wind Plasma
Dastgeer Shaikh, G. P. Zank
Observations of interstellar scintillations at radio wavelengths reveal a Kolmogorov-like scaling of the electron density spectrum with a spectral slope of -5/3 over six decades in…
Magnetohydrodynamic simulation of the interaction between two interplanetary magnetic clouds and its consequent geoeffectiveness
Ming Xiong, Huinan Zheng, S. T. Wu +2
Numerical studies of the interplanetary "multiple magnetic clouds (Multi-MC)" are performed by a 2.5-dimensional ideal magnetohydrodynamic (MHD) model in the heliospheric meridiona…
Self-Organization in a Driven Dissipative Plasma System
Dastgeer Shaikh, B. Dasgupta, Q. Hu +1
We perform a fully self-consistent 3-D numerical simulation for a compressible, dissipative magneto-plasma driven by large-scale perturbations, that contain a fairly broader spectr…
Spectral Properties of Electromagnetic Turbulence in Plasmas
Dastgeer Shaikh, P K Shukla
We report on the nonlinear turbulent processes associated with electromagnetic waves in plasmas. We focus on low-frequency (in comparison with the electron gyrofrequency) nonlinear…
Whistler Wave Cascade in Solar Wind Plasma
Dastgeer Shaikh
Nonlinear three dimensional, time dependent, fluid simulations of whistler wave turbulence are performed to investigate role of whistler waves in solar wind plasma turbulence in wh…
