Visualization of rapid electron precipitation via chorus element wave–particle interactions [PDF]
Nature Communications, 2019 Electron precipitation plays major role in magnetospheric physics and space weather. Here the authors show nonlinear behavior of the wave–particle interaction in the magnetosphere as the evolution of chorus electromagnetic waves detected by the Arase ...

Simulation of radiation belt wave-particle interactions in an MHD-particle framework
Frontiers in Astronomy and Space Sciences, 2023 In this paper we describe K2, a comprehensive simulation model of Earth’s radiation belts that includes a wide range of relevant physical processes. Global MHD simulations are combined with guiding-center test-particle methods to model interactions with ...

ULF waves with drift resonance and drift-bounce resonance energy sources as observed in artificially-induced HF radar backscatter [PDF]
Annales Geophysicae, 2001 HF radar backscatter which has been artificially-induced by a high power RF facility such as the EISCAT heater at Tromsø has been demonstrated to provide ionospheric electric field data of unprecedented temporal resolution and accuracy. Here such data

A comparison study between observations and simulation results of Barghouthi model for O+ and H+ outflows in the polar wind [PDF]
Annales Geophysicae, 2011 To advance our understanding of the effect of wave-particle interactions on ion outflows in the polar wind region and the resulting ion heating and escape from low altitudes to higher altitudes, we carried out a comparison between polar wind ...
