On 23 November 2012, a sudden dropout of the relativistic electron flux was observed after an interplanetary shock arrival. The dropout peaks at ∼1 MeV and more than 80% of the electrons disappeared from the drift shell. Van Allen twin Probes observed a sharp electron flux dropout with clear...
Deformation and evolution of solar wind discontinuities through their interactions with the Earth's bow shockDownload
Kabin, Konstantin, Keika, Kunihiro, Rankin, Robert, Carr, C. M., Carlson, C. W., Glassmeier, Karl-Heinz, Magnes, Werner, Lucek, Elizabeth, McFadden, J. P., Dandouras, Iannis, Auster, H. U., Sibeck, D. G., Fornacon, K.-H., Angelopoulos, Vassilis, Baumjohann, W., Nakamura, Rumi
The present study examines the interaction of solar wind discontinuities with the Earth's bow shock, using multipoint observations in the magnetosheath by Time History of Events and Macroscale Interactions During Substorms (THEMIS), Cluster, and Double Star TC1. We focus on the deformation and...
The propagating source method for solving the time-dependent Boltzmann equation describing particle propagation in a magnetically turbulent medium is extended to a more realistic case that includes focusing and adiabatic deceleration. The solutions correspond to beam propagation in the solar...
A model is presented that describes the excitation of density perturbations and parallel electric fields by standing shear Alfven waves on dipole fields in Earth's magnetosphere. The model includes the effects of electron inertia and gyro-kinetic dispersion, accounting for field-aligned...
We describe nonlinear resonance absorption of compressional Alfven waves in a model magnetosphere. It is shown that the ponderomotive force of excited standing shear Alfven waves can lead to nonlinear saturation and spatial structuring of field line resonances and that in low-beta plasmas...
We present theory and numerical simulations of strong nonlinear effects in standing shear Alfven waves (SAWs) in the Earth's magnetosphere, which is modeled as a finite size box with straight magnetic lines and (partially) reflecting boundaries. In a low beta plasma it is shown that the...
Inverse resonance absorption in an inhomogeneous magnetized plasma
The linear mode conversion of a plasma wave to a light wave in a magnetized plasma has been examined theoretically and by computer simulation. This conversion is the inverse of resonance absorption exhibiting an identical dependence on magnetic field and density scale length with an optimum...
The effects of a magnetic field on the Raman and two‐plasmon decay instabilities are studied in the region of the quarter‐critical density of laser produced plasmas where both are coincident. Two‐plasmon decay of the incident extraordinary wave into two upper‐hybrid waves may now occur in the...
