The expanded bow shock on and around "the day the solar wind almost disappeared" (11 May 1999) allowed the Geotail spacecraft to make a practically uninterrupted 54-h-long magnetosheath pass near dusk (16:30-21:11 magnetic local time) at a radial

With its ≈12 h-long period of strongly northward magnetic field, the coronal mass ejection which passed Earth on April 11, 1997 afford an excellent opportunity of study Kelvin-Helmholtz (KH) activity at the dayside magnetopause as a function of the

The modulational instability of a linearly polarized, strong, electromagnetic wave in a (unmagnetized) positron-electron plasma is analyzed using relativistic two-fluid hydrodynamics to properly account for physical regimes of very high temperatures.

We study the modulational instability of an electron-positron plasma with relativistic temperatures and phonon damping. It is shown that when the phonon damping is O(1) or O(e), a modulational instability appears even for classical temperatures. When

We study the dispersion relation of left-hand-polarized Alfven waves in multicomponent plasmas. If initially the plasma components are not drifting relative to each other, the Alfven waves propagate until they meet the gyrofrequency of the species wi

It is shown that the velocity threshold of the right-hand-polarized ion-ion resonant instability decreases with decreasing gyrofrequency values of the beam ions, and also, the system can become unstable for very small beam concentrations. In order to

We study the stability of the cold-plasma dispersion relation for circularly polarized waves in a plasma composed of an ion background and an ion beam. The presence of the beam introduces a resonant branch into the dispersion relation for right-hand-

It is well known that the temperature anisotropy of either the minority or majority species in a two-component plasma can make the electromagnetic ion-cyclotron mode unstable. This instability may be particularly relevant in tokamak experiments where
