Ion Acceleration Efficiency at the Earth’s Bow Shock: Observations and Simulation Results

O+ ion beams reflected below the Martian bow shock: MAVEN observations

Simulation of a Perpendicular Bow Shock

Mach number cases, whose laminar structures have been adequately described by magnetosonic Simulations of a high Mach number shock with wavetrains that scale as C/mpe ITidman and Krall, parameters typical of the earth's bow hock have 1971). Computer simulations including both been performed using a hybrid (particle ions, electron and ion scales, have significantly fluid electrons) code. The sim...

Pulsar bow - shock nebulae II . Hydrodynamical Simulation

We present hydrodynamical simulations, using a 2-D two component model (ambient medium and pulsar wind have different specific heat ratios), of bow shocks in a representative regime for pulsar wind driven bow-shock nebulae. We also investigate the behaviour of a passive toroidal magnetic field wound around the pulsar velocity direction. Moreover we estimate the opacity of the bow-shock to penet...

Ion injection and shock acceleration in the outer

Voyager 2 data from 47 AU shows a delay of about 6 days between the arrival of interplanetary shock fronts and the peaks in the 0.52 1.45 MeV energetic proton ux. Similar data recorded when Voyager 2 was at 5 AU shows that the shock fronts and the peaks in the energetic proton ux are virtually coincident. If injection and acceleration took place at the shock fronts one would expect the peaks in...
