We investigated the relation between the geotail current sheet structure and the anisotropy of the ion temperature in the plasma sheet. Current density distribution in the geomagnetic tail is shown not to depend on the ratio between the parallel a

In this study we test a stream function method suggested by Israelevich and Ershkovich for instantaneous reconstruction of global, high-latitude ionospheric convection patterns from a limited set of experimental observations, namely, from the elec

A new method to reconstruct the instantaneous convection pattern in the Earth's polar ionosphere is suggested. Plasma convection in the polar cap ionosphere is described as a hydrodynamic incompressible flow. This description is valid in the regio

Multiple crossings of the magnetotail current sheet by a single spacecraft give the possibility to distinguish between two types of electric current density distribution: single-peaked (Harris type current layer) and double-peaked (bifurcated curr

Magnetic tension in the tail of the classical induced magnetosphere produced by field line draping is directed downstream along the external plasma flow. This is confirmed by the calculation of tension in magnetospheres of Venus and comet Halley whic

The conventional Jeans model is modified by the addition of electric charging. The standard procedure of kinetic treatment results in a dispersion relation which describes both the Jeans instability and Langmuir oscillations, with the analog of Landa

Stability of the plane tangential discontinuity (TD) interface in a multi-component dusty plasma (ions, electrons, neutral particles and charged dust) is considered in hydrodynamical approximation. The criterion of stability does not depend on the pr

Analysis of Geotail magnetic data enables us to reveal the antisunward electric current flowing along the tail axis. To our knowledge, observation of this current has not been reported yet. Distributions of the magnetic field and electric current den

The existence of the radial component of the electric current flowing toward the Sun is revealed in numerical simulation. The total strength of the radial current is ~ A. The only way to fulfil the electric current continuity is to close the radial e
