Magnetosheath Structure in an Anisotropic Plasma Model

Astrophysics and Space Science, 2000
Variations of the magnetic field and plasma parameters across the Earth's magnetosheath are calculated for an anisotropic plasma in the Chew-Goldberger-Low approximation. Additionally, proton pitch-angle diffusion is taken into account as the energy transfer mechanism between the direction perpendicular and parallel to the magnetic field.

MHD simulations of the magnetosheath

Advances in Space Research, 1994
Ideal magnetohydrodynamic (MHD) simulations of the dayside magnetosheath are reported. The calculations show a depletion layer near the magnetopause and a new stagnation flow structure. The stagnation flow appears to be a generalization of the stagnation line for ideal MHD.

Turbulence Surrounding Magnetosheath Jets: Are Pressure Enhancement Stirring the Magnetosheath?

Earth’s magnetosheath, the region between Earth’ magnetic field and the bow shock, gives rise to a plethora of transients, waves, and instabilities. Each effect changes the plasma parameter distribution, impacting the behaviour of the plasma that finally hits our magnetic field. Turbulence plays a crucial role in how energy injected

A comparison of measured parameters of magnetosheath plasma with predictions of a new magnetosheath-magnetosphere model

Cosmic Research, 2008
A possibility of description of the properties of plasma flow in the magnetosheath using the INME hydrodynamical model is considered on the basis of a comparison with experimental data. This model is characterized by a high degree of self-consistency and, in particular, makes it possible to determine positions of the boundaries of the magnetosheath ...

Magnetosheath Interaction with the High Latitude Magnetopause

Surveys in Geophysics, 2005
We present both statistical and case studies of magnetosheath interaction with the high-latitude magnetopause on the basis of Interball-1 and other ISTP spacecraft data. We discuss those data along with recently published results on the topology of cusp-magnetosheath transition and the roles of nonlinear disturbances in mass and energy transfer across ...

Ion propagation in the magnetosheath

Journal of Geophysical Research: Space Physics, 1984
The transport of test ions through the magnetosheath depends upon the macroscopic structure defined by the average magnetic and flow fields, B0 and U, and the fluctuating fields, δE and δB, encountered by the particles. In this paper an approximate model is used to generate the macroscopic configuration: it satisfies the jump conditions at the bow ...

Comparison of a new magnetosphere–magnetosheath model with Interball-1 magnetosheath plasma measurements

Planetary and Space Science, 2005
Abstract We report a testing of the earlier developed in the Institute of Mechanics of the Bulgarian Academy of Sciences numerical data-based 3D model of the system magnetosphere–magnetosheath with real satellite data. The model is a result of a self-consistent solution of two tasks: (i) Chapman–Ferraro problem for an arbitrary 3D magnetopause with ...

Adventures in the magnetosheath: two decades of modeling and planetary applications of the Spreiter magnetosheath model

Planetary and Space Science, 2002
Abstract A review is given of the author's two decades of magnetosheath modeling work with John Spreiter Beginning in the early 1970s, a sequence of computational magnetosheath submodels that extended and refined John's basic model were developed and successfully applied to virtually every planet in the solar system including the terrestrial planets ...

On the structure of magnetosheath jets

Plasma structures with the enhanced dynamic pressure, density, or speed are often observed in the Earth’s magnetosheath. These structures, known as magnetosheath (MSH) jets, can be detected downstream quasi-perpendicular and quasi-parallel bow shocks.
