Short large-amplitude magnetic structures and whistler wave precursors in a full-particle quasi-parallel shock simulation

Large Amplitude, Short Wave Peristalsis

6 Valveless, tubular pumps are widespread in the animal kingdom, but the mechanism by which these pumps generate fluid flow are often in dispute. Where the pumping mechanism of many organs was once described as peristalsis, other mechanisms, such as dynamic suction pumping, have been suggested as possible alternative mechanisms. Peristalsis is often evaluated using criteria established in a tec...

Alfvén wave transmission and particle acceleration in parallel shock waves

We study Alfvén wave transmission through parallel shocks. First, the paper corrects for mistakes made in a previous study by Campeanu & Schlickeiser on the same subject. It is shown, contrary to CS, that first-order Fermi acceleration by multiple shock crossings is generally more effective than stochastic acceleration in the downstream region. Moreover, we demonstrate that in a large region of...

Wave-particle interactions with parallel whistler waves: Nonlinear and time-dependent effects revealed by particle-in-cell simulations

Quasi-one-dimensional particle-in-cell simulation of magnetic nozzles

A method for the quasi-one-dimensional simulation of magnetic nozzles was developed and simulations of a magnetic nozzle were performed. The effects of the density variation due to plasma expansion and the magnetic field forces on ion acceleration were investigated. The density variation only weakly affects ion acceleration. Magnetic field forces acting on the electrons were found to be respons...
