It turns out that the shock phenomenon is a multi-scale non-linear problem in time and space. These shocks, depending on the direction of the upstream magnetic field, are distinguished as quasi-perpendicular and quasi-parallel Collisionless Shocks in the Heliosphere book which exhibit different behaviours, reflecting particles back upstream and generating high electromagnetic wave intensities.

Phys Plasmas — In analogy to the non-relativistic approach, where the trapped population is described with a flat-top profile 2129we formulate the relativistic distribution of trapped particles as withwhich goes to in the non-relativistic approximation.

Such shocks are naturally magnetised implying that the magnetic field plays an important role in their evolution and dynamics. Shocks naturally appear from the collision of two plasma slabs and are of electromagnetic character if transverse electromagnetic modes drive the shock formation process or of electrostatic character if longitudinal instabilities dominate.

In order to define parameter regimes specifically, it is assumed that ion reflection from the potential has just set in, which is equivalent to consider. J Geophys Res Shock waves are an important feature of solar system plasmas, from the solar corona out to the edge of the heliosphere.

The quasi-parallel shock; 6. As a result of the theoretical analysis, parameter regimes of the dominating electrostatic or electromagnetic shock character can be defined, which are summarised in Figure 1.

Collisionless Shocks in Space Plasmas : Structure and Accelerated Particles

Collisionless Shocks in the Heliosphere book of subcritical shocks in space are sparse, mostly restricted to interplanetary space.

See our disclaimer An engaging introduction to collisionless shocks in space plasmas, presenting a complete review, from first principles to current research. Since instabilities of the Weibel-type are very efficient in highly anisotropic plasmas, low thermal and high fluid velocities enhance the shock formation process 9.

Particle acceleration and turbulence at Collisionless Shocks in the Heliosphere book shocks become possible and important. An insert about it was published also in the Instrumentation Newsletter a world-wide publication for Graphical System Design, First Quarter, Such shocks are naturally magnetised implying that the magnetic field plays an important role in their evolution and dynamics.

Recent developments of laboratory shock experiments has started to bring some new insights in the physics of space plasma and astrophysical shock waves.

Connections with possible experiments are made and we show that these distinct regimes can already be explored in the laboratory. The upstream populations of free streaming electrons and ions are affected by the shock potential, leading to a population of free streaming and trapped electrons downstream.

The Version of Record is available online at Coherent shock acceleration; 8. LemoineG. We have developed a 3D version that can accurately predict conditions in which shock waves form- and therefore assist in designing experimental schemes. Space Sci Rev — Particle acceleration and turbulence at such shocks become possible and important.

The study of electromagnetic shocks in the laboratory is difficult because of the long shock formation time at low fluid velocities 10which are now obtained experimentally 1112or the need to drive relativistic speeds, which requires very intense lasers The main emphasis is, however, on super-critical shocks where the anomalous dissipation is insufficient to retard the upstream flow.

Diffusive shock acceleration; 7. He has participated in numerous scientific space missions since the mids and has been a Principal Investigator on the Ulysses and Cluster missions.
