Dayside magnetopause reconnection
Journal of Geophysical Research: Space Physics, 1985The Petschek model of magnetic field line reconnection is generalized for magnetopause‐like conditions to enable a comparison of data and theory. The two‐dimensional, compressible MHD model considered reveals four discontinuities which are necessary to match the different magnetic fields and plasma parameters inside and outside the magnetopause.

Reviews of Geophysics, 1987
The explosive growth of magnetopause and bowshock research reported by Russell and Greenstadt [1983] has continued unabated through the 1983 to 1986 quadrennium. Shock research has gone far beyond the tentative exploratory work seen in the last two quadrennia: a sizable volume of collisionless shock parameter space has been explored both in careful ...

Wave-coupling at the magnetopause
Astrophysics and Space Science, 1974The 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

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

On the Dipolarization Front and Magnetopause: 2. Evidence of Interchange Instability at Magnetopause
Journal of Geophysical Research: Space PhysicsAbstract 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.

Tearing modes at the magnetopause
Journal of Geophysical Research: Space Physics, 1981This 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.

The location and shape of the magnetopause
Planetary and Space Science, 2002Abstract 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.

The Jovian Magnetosphere And Magnetopause
1976It 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.

Tearing modes at the magnetopause
Journal of Geophysical Research: Space Physics, 1996It 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
