DOWNLOAD EBOOKA perpendicular collisionless shock wave in a high beta infinite plasma is considered. The effects of the inhomogeneity of the shock front have been analyzed. It was found that the ions are heated up and that the resonant particles see a larger component of the electric field in the direction of he inhomogeneity. From the linear stability it was found that the fastest growing unstable modes inside the shock front are the beam-cyclotron and pure cyclotron modes. The effects of high beta values on these instabilities have been investigated. A new theory has been developed to handle the non-linear evolution of unstable modes. Equations governing the structure of the shock front valid for low as well as high Mach numbers have been derived. (Author).

DOWNLOAD EBOOKThe present book provides a contemporary systematic treatment of shock waves in high-temperature collisionless plasmas as are encountered in near Earth space and in Astrophysics. It consists of two parts. Part I develops the complete theory of shocks in dilute hot plasmas under the assumption of absence of collisions among the charged particles when the interaction is mediated solely by the self-consistent electromagnetic fields. Such shocks are naturally magnetised implying that the magnetic field plays an important role in their evolution and dynamics. This part treats subcritical shocks which dissipate flow energy by generating anomalous resistance or viscosity. The main emphasis is, however, on super-critical shocks where the anomalous dissipation is insufficient to retard the upstream flow. These shocks, depending on the direction of the upstream magnetic field, are distinguished as quasi-perpendicular and quasi-parallel shocks which exhibit different behaviours, reflecting particles back upstream and generating high electromagnetic wave intensities. Particle acceleration and turbulence at such shocks become possible and important. Part II treats planetary bow shocks and the famous Heliospheric Termination shock as examples of two applications of the theory developed in part I.

DOWNLOAD EBOOKA model for a turbulent shock wave with a structure determined by ion wave instabilities is discussed. Quasi-linear theory for spatially growing waves is used to examine the spatial buildup of the turbulent spectrum in the leading edge of the shock transition. Although the principal calculations are made for an electrostatic shock, the response of a weak magnetic field in the plasma to such a thin ion-wave shock is also discussed. It is suggested that the earth's bow shock in the supersonic solar wind may sometimes have a structure of the type described here and a comparison with satellite data for this shock wave is made.

DOWNLOAD EBOOKA kinetic equation is derived for interacting waves in a weakly nonequilibrium rarefied plasma. The relation between the laminar and turbulent theories of shock waves without collisions in a strong magnetic field is discussed. An estimate of the turbulent width of shock waves is made on the basis of the kinetic equation. (Author).
