The structure of the magnetopause

Planetary and Space Science, 1969
Abstract 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 ...

Wave-coupling at the magnetopause

Astrophysics and Space Science, 1974
The paper considers wave coupling for an arbitrary direction of propagation on the basis of single fluid hydromagnetic equations appropriate for a rarefied plasma. The analysis is used to study the transfer of solar wind momenta into the magnetosphere. It is found that wave refraction is significant only during disturbed conditions for waves travelling

Magnetopause rotational forms

Journal of Geophysical Research, 1974
Magnetic field data from the Goddard Space Flight Center magnetometer experiment on board Ogo 5 are analyzed by the minimum-variance technique for two magnetopause crossings, believed to provide the best evidence presently available of magnetopause rotational discontinuities. Approximate agreement with predictions from MHD and first-order orbit theory

Tearing modes at the magnetopause

Journal of Geophysical Research: Space Physics, 1981
This paper examines the possible occurrence of tearing modes in the dayside magnetopause. First, the expected magnetic signature of tearing, as obtained from existing theory, is reviewed. Magnetometer data from one terrestrial magnetopause crossing and one crossing of Jupiter's magnetopause are then examined in detail.

Transfer processes in the magnetopause

Journal of Geophysical Research, 1968
Magnetic field fluctuations in vicinity of magnetopause boundary layer imply substantial transfer of particles and momentum from solar wind to ...

Tearing modes at the magnetopause

Journal of Geophysical Research: Space Physics, 1996
It is shown that the shear flow present in the magnetopause current layer can destabilize the tearing modes depending upon the Mach number profiles. Using a variational principle, an heuristic stability criterion based on the form of the Mach number profile is obtained. This criterion could be used as a handy tool to search for tearing mode instability

On the Dipolarization Front and Magnetopause: 2. Evidence of Interchange Instability at Magnetopause

Journal of Geophysical Research: Space Physics
Abstract Interchange instability is a macroscopic instability that commonly develops when the centrifugal acceleration opposes the acceleration induced by the density gradient at the interface between two regions.

The Jovian Magnetosphere And Magnetopause

1976
It is convenient to divide the magnetosphere into three regions. The inner magnetosphere extends from the surface to about 25 7R J and is dominated by the basically dipolar field. The outer magnetosphere, on the sunward side, occupies a layer roughly 15R J thick just inside the magnetopause.

The location and shape of the magnetopause

Planetary and Space Science, 2002
Abstract In this paper, we provide a comprehensive review on the development of magnetopause location research over the past four decades, starting from John R. Spreiter's early fundamental work on the shape of the magnetopause as a function of dipole tilt angle.

Magnetopause reconnection rate

Journal of Geophysical Research, 1974
Discussion of certain aspects of the magnetic field reconnection process at the magnetopause. It is argued that the upper limits on reconnection derived by Petschek (1964), on the one hand, and Yeh and Axford (1970) and Sonnerup (1970), on the other, may be reconciled, at least qualitatively.
