The Magnetosphere-Solar Wind boundary is treated as a tangential discontinuity between collisionless plasma described by C.G.L. equations. An estimate is made, analytically, of the minimum shear speed required to render the interface unstable for propagation in any arbitrary direction.

The Structure of the Magnetopause
Planetary and Space Science, 2003Abstract The solar wind is a magnetized flowing plasma that intersects the Earth's magnetosphere at a velocity much greater than that of the compressional fast mode wave that is required to deflect that flow. A bow shock forms that alters the properties of the plasma and slows the flow, enabling continued evolution of the properties of the flow on ...

Structure of tangential discontinuities at the magnetopause: the nose of the magnetopause
Journal of Atmospheric and Terrestrial Physics, 1978Abstract Observations show that the magnetopause can sometimes be represented as a tangential discontinuity in the magnetic field. In this paper, we use a theoretical model of steady-state tangential discontinuities to analyze the microscale structure of the nose of the magnetopause.

Probing the structure of the magnetopause
Science, 2017Magnetospheres The magnetopause is the boundary in space that separates the region dominated by Earth’s magnetic field (the magnetosphere) from the surrounding solar wind. The four spacecraft of NASA’s Magnetospheric Multiscale (MMS) mission have repeatedly flown in formation through the magnetopause, measuring the properties of the plasma and magnetic

The magnetopause of a symmetric quadrupole embedded in a parallel streaming plasma is calculated by means of the method of the Chapman‐Ferraro problem. The results are discussed with special attention being given to the position of the neutral points for the two symmetric cases of interaction.

On the equilibrium of the magnetopause
Journal of Geophysical Research, 1970The existence of an equilibrium layer between a magnetic field and a field-free stream of cold plasma, moving perpendicularly to the field, was shown many years ago by Ferraro. Recently, Parker treated the interaction of a plasma stream and a magnetic field under somewhat different assumptions.

Reviews of Geophysics, 1971
This paper reviews present understanding of the internal structure of the thin boundary layer, termed the magnetopause, that separates the distorted geomagnetic field in the magnetosphere from the flow of solar plasma in the magnetosheath. The fundamental theoretical concepts of the subject are introduced by considering the structure of the boundary ...

Transport Mechanisms at the Magnetopause
1979Mass, momentum, and energy transferred from the solar wind and magnetosheath into the magnetosphere must cross the boundary of the earth’s magnetic field, the magnetopause. This paper reviews the possibilities for convective and diffusive transport across the boundary and discusses the dependence of such processes on the orientation of the ...

The structure of the magnetopause
Planetary and Space Science, 1969Abstract Previous work on the structure of the boundary layer between a cold plasma and a vacuum magnetic field is extended to include the effect of a transverse velocity component perpendicular to the applied field. The exact equations of the problem, taking into account the electrostatic field arising from charge separation in the boundary, are ...

Abstract A review of empirical data-based models of the magnetopause and a comparative analysis are given with special attention to the dynamics of the dayside boundary. Recently different research groups have presented new magnetopause models as an alternative to the model of Roelof and Sibeck (1993, J. Geophys. Res. 94, 15, 125).
