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.

The cusp-magnetosheath interface

Journal of Geophysical Research, 1976
Three Heos 2 passes through the distant cusp-magnetosheath transition in summer 1973 are described. By combining data from three different experiments on board Heos 2 it has been possible to identify a distinct transition from a ‘stagnant’ plasma (the distant cusp) to a region of ‘reduced flow’ magnetosheath.

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.

Magnetosheath electrostatic turbulence

Journal of Geophysical Research: Space Physics, 1979
By using measurements with the University of Iowa plasma wave experiment on the Imp 6 satellite a study has been conducted of the spectrum of electrostatic plasma waves in the terrestrial magnetosheath. Electrostatic plasma wave turbulence is almost continuously present throughout the magnetosheath with broadband (20 Hz to 70 kHz) rms field intensities

Near-magnetopause magnetosheath in 3D gasdynamic module of the numerical magnetosheath–magnetosphere model

Advances in Space Research, 2016
Abstract This paper describes an approach to a theoretical interpretation of Interball-1 satellite measurements data in two cases of the satellite’s crossings of the magnetosheath. An interpretation is made of both the measured crossings of the magnetosheath boundaries and the behavior of the registered plasma parameters. In our case, it is the value

The magnetosheaths of the outer planets

Planetary and Space Science, 2002
Abstract This paper provides a review of past work on the magnetosheaths of the outer planets and also provides the most complete look to date at the plasma parameters in these magnetosheaths. We find that proton distributions in the magnetosheaths of Jupiter, Saturn, and Neptune (but not Uranus) are well represented by two Maxwellians with the same ...

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 ...

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

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.

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 ...
