Waves in plasmas generated by a rotating magnetic field and implications to radiation belts. "At the heart of the theory is a pair of old, dense stars called white dwarfs, orbiting each other so closely that their gravitational forces create violent tidal waves of plasma that break near the surfaces of the stars. Super-heated plasma would be injected into the vortex, then the outside of the sphere would be hit with 200 computer-synchronized pistons travelling 100 meters per second. To the description of surface waves in deep water, and the KP-I equation occurs in the description of capillary gravitational waves on a liquid surface, but also when one considers magneto-acoustic waves in plasma (Zhdanov, 1984) etc. Work was on the boundaries of plasmas and ion rarefaction waves—most of the work was experimental using a Langmuir probe in the basement lab in Oxford's Engineering Science building. Into vacuum, valid for arbitrary magnetization. We also consider expansion into cold unmagnetized external medium both for stationary initial conditions and for initially moving plasma, as well as reflection of rarefaction wave from a wall. Whistler waves are present in solar wind plasma. We present experiments and theoretical studies on the propagation of Josephson fluxons and electromagnetic waves in parallel arrays of Josephson junctions in the limit of small discreteness. Only compressive structures (density/potential hill) are found to exist that evolve due to the propagation of two types of waves, namely fast wave and slow wave. As such, they have been studied as models for many important natural phenomena, such as deep water waves, ion-acoustic waves in plasmas, and propagation of laser pulses in optical fibers. Magnetohydrodynamic (MHD) wave behaviour in the neighbourhood of coronal null points is a fundamental plasma process. The dynamics of gravity waves is potentially climate modification when it is coupled with plasma creation. Confirmation that interacting magnetic plasma waves can generate “daughter” waves of a higher frequency supports the current picture of how turbulence leads to heat in astrophysical plasma.
