MHD-modelling of the magnetosheath

Planetary and Space Science, 2002
Abstract A short discussion of some problems of magnetosheath physics is presented. In particular, anisotropic MHD models of the magnetosheath are discussed. A method to estimate the value of the characteristic relaxation time (τ) of the proton temperature anisotropy from experimental data is proposed.

MHD properties of magnetosheath flow

Planetary and Space Science, 2002
Abstract We discuss four aspects of magnetosheath flow that require MHD for their calculation and understanding. We illustrate these aspects with computations using a numerical MHD code that simulates the global magnetosphere and its 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 ...

Conformally-mapped planetary magnetosheath model

2023
A high-precision model of steady-state plasma flow and magnetic field in the planetary magnetosheath region is proposed by introducing the concept of conformal mapping and transforming the Kobel-Flueckiger scalar potential (the exact solution of Laplace equation) from the parabolic boundaries (bow shock and magnetopause) into arbitrary shape of ...

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.

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

Mirror instability in the magnetosheath

Advances in Space Research, 1994
We describe mirror mode structures observed by ISEE 1 and ISEE 2. We cite an example where there is a good correlation between signals measured at the two spacecraft while they are 2250 km apart, and another example where the correlation is much poorer, although the spacecraft are only 340 km apart.

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 ...

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.
