Self‐consistent electron acceleration due to inertial Alfvén wave pulsesournal of Geophysical Research: Space Physics, 110(A10), [pp

Watt, Clare E. J., Wright, D. M. , Rankin, Robert, Rae, I. Jonathan
We present self-consistent kinetic simulations of the electron response to finite duration shear Alfven wave pulses in a magnetized plasma. In Earth's magnetosphere, the evidence suggests that parallel electric fields in inertial scale shear Alfven waves can accelerate electrons in the...

Self‐consistent wave‐particle interactions in dispersive scale long‐period field‐line‐resonances
Download2007
Rankin, Robert, Samson, John C., Watt, Clare E. J.
Using 1D Vlasov drift-kinetic computer simulations, it is shown that electron trapping in long period standing shear Alfvén waves (SAWs) provides an efficient energy sink for wave energy that is much more effective than Landau damping. It is also suggested that the plasma environment of low...

Self‐focusing and ion wave generation in laser‐produced plasmas
1988
Rankin, Robert, Marchand, Richard, Capjack, C. E.
Two‐dimensional hydrodynamic simulations of laser light self‐focusing in a hydrogen plasma are presented. The simulation code includes a model for laser beam propagation which accounts for inverse bremsstrahlung absorption, refraction, diffraction, and ponderomotive forces. A Gaussian hot spot,...

Shear Alfvén waves on stretched magnetic field lines near midnight in Earth's magnetosphere

Tikhonchuk, Vladimir T., Rankin, Robert, Fenrich, Frances
The spectrum of toroidal standing shear Alfvén waves (SAWs) is derived for a stretched magnetic field line geometry that is approximated by the Tsyganenko 96 magnetic field model. The model is applied to field lines near the midnight meridional plane. It is demonstrated that the fundamental mode...

Tikhonchuk, V. T., Voronkov, I., Samson, J. C., Rankin, Robert
The three-dimensional, nonlinear evolution of a shear how (or Kelvin-Helmholtz (KH)) instability driven by a large-amplitude shear Alfven wave (SAW) in the Earth's magnetosphere is studied by using numerical solutions to the complete set of ideal magnetohydrodynamic equations. An initial setup is...

Sydorenko, Dmytro, Rankin, Robert
A two-dimensional numerical model of low-altitude auroral flux tubes has been developed for simulation of coupling between the magnetosphere and the ionosphere. The model considers a realistic ionosphere with multiple ion and neutral species, collisions, cooling and heating processes, as well as...

Simulation of O+ upflows created by electron precipitation and Alfvén waves in the ionosphere
Download2013
Sydorenko, Dmytro, Rankin, Robert
A two-dimensional model of magnetosphere-ionosphere coupling is presented. It includes Alfven wave dynamics, ion motion along the geomagnetic field, chemical reactions between ions and neutrals, collisions between different species, and a parametric model of electron precipitation. Representative...

Frycz, P., Samson, J. C., Rankin, Robert
Using a compressible, three-dimensional resistive monohydrodynamic (MHD) computer simulation code, we examine the evolution of standing wave field line resonances (FLRs) in the nightside of the Earth's magnetosphere. The MHD code that is used allows for a full nonlinear description and enables us...

Schriver, David, Trávníček, Pavel M., Rankin, Robert, Paral, Jan
Two flybys of Mercury by the NASA MESSENGER spacecraft on January 14 and October 6, 2008 provide insight into the spatial distribution of the heavy ion exosphere around the planet. The relatively quiet solar wind conditions and interplanetary magnetic field (IMF) orientation allow us to compare...

“Zebra stripes” are newly found energetic electron energy-spatial (L shell) distributed structure with an energy between tens to a few hundreds keV in the inner radiation belt. Using high-quality measurements of electron fluxes from Radiation Belt Storm Probes Ion Composition Experiment (RBSPICE)...
