TLDR
The types of discontinuity which can occur in a magnetohydrodynamic fluid with anistotropic pressure are discussed in this article, and rules are given for the identification of the type of discontinuities together with equations to determine their orientation and velocity.About:

Jump conditions for pressure anisotropy and comparison with the Earth's bow shock
D. F. Vogl,D. F. Vogl,Helfried K. Biernat,Helfried K. Biernat,Nikolai V. Erkaev,Charlie J. Farrugia,S. Mühlbachler,S. Mühlbachler +7 more
TL;DR: In this paper, the authors study the magnetic field and plasma param- eters downstream of a fast shock, as functions of upstream parameters and downstream pressure anisotropy, and compare their theory with plasma and magnetic field parameters measured by the WIND spacecraft.

The magnetotail boundary and energy transfer processes
Daniel W. Swift,Lou C. Lee +1 more
TL;DR: In this paper, a particle code is used to simulate the magnetopause region in the high latitude geomagnetic tail in which the magnetic field undergoes a significant increase in going from the magnetosheath to the magnetotail lobe.

On steady field‐aligned double‐adiabatic flow
Abstract: The paper summarizes the four general double-adiabatic invariants governing ideal MHD flow in a narrow tube and renders them in a form suitable for the calculation of flow in tubes of nonconstant cross-sectional area. Results for converging-diverging flux tubes are developed and compared to single-adiabatic results which are identical to those for ordinary gasdynamic flow. It is found that in certain parameter regimes the governing equation for the vector potential is elliptic and can be reduced to Laplace's equation by simple stretching of one coordinate. In other regimes the equation is hyperbolic, indicating the presence of wave patterns. The relevance of these results to flow over magnetopause undulations, including flux transfer events, is discussed.

Investigation of the outer and inner low-latitude boundary layers
TL;DR: In this paper, the authors analyzed 22 AMPTE/IRM crossings of the day-side low-latitude boundary layer for which a dense outer part can be distinguished from a dilute inner part.

Shock Jump Conditions Modified by Pressure Anisotropy and Heat Flux for Earth's Bowshock
L. H. Lyu,J. R. Kan +1 more
TL;DR: In this article, the effects of pressure anisotropy and backstreaming heat flux on the fast and slow shock jump conditions are studied parametrically and the minimum critical Mach number is shown to increase from unity as qx becomes increasingly greater than qx.

Discontinuities in the solar wind
D. S. Colburn,Charles P. Sonett +1 more
TL;DR: In this paper, the existence of a field of MHD discontinuities in the solar wind should make possible the generation of ensembles of shocks and contact surfaces, which can be treated as shock wave or contact surface.

Micro-scale structures in the interplanetary medium
TL;DR: In this paper, the authors describe and analyze the following micro-scale structures which were found in combined interplanetary magnetic field and plasma data obtained by the deep-space probe Pioneer-6: (1) Several types of simultaneous discontinuities in the magnetic fields and plasma parameters; (2) at least one clear example of a transitional region (D-sheet) associated with a plasma discontinuity; (3) other D-sheets which give evidence of magnetic field annihilation; inhomogeneous isothermal regions in which the square of the magnetic-field intensity is proportional to the
