Ducted propagation of chorus waves: Cluster observations [PDF]

Annales Geophysicae, 2011
Ducted propagation of whistler waves in the terrestrial magnetosphere-ionosphere system was discussed and studied long before the first in-situ spacecraft measurements.

Substorm Effects on Chorus Emissions Modulated by ULF Waves

Geophysical Research Letters
Although cross‐scale wave‐particle interactions play a critical role in energy transfer in the magnetosphere, the influence of geomagnetic activity on the physical mechanisms involved remains unclear.

Combined Effects of Equatorial Chorus Waves and High-Latitude Z-Mode Waves on Saturn's Radiation Belt Electrons

Geophysical Research Letters, 2019
In this paper, we examined the combined effects of equatorial chorus waves and high‐latitude Z‐mode waves on the energy and pitch angle distribution of Saturn's radiation belt electrons.

Short Chorus Wave Packets: Generation Within Chorus Elements, Statistics, and Consequences on Energetic Electron Precipitation. [PDF]

J Geophys Res Space Phys, 2022
AbstractShort and intense lower‐band chorus wave packets are ubiquitous in the Earth's outer radiation belt. In this article, we perform various Vlasov hybrid simulations, with one or two triggering waves, to study the generation of short chorus packets/subpackets inside long rising tone elements.

Quantifying the Size and Duration of a Microburst‐Producing Chorus Region on 5 December 2017 [PDF]

Geophysical Research Letters, 2022
Microbursts are impulsive (30 keV) precipitation (FIREBIRD II and AC6 CubeSats, POES) to determine the size of the microburst‐producing chorus source region beginning on 5 December 2017.

Butterfly Distributions of Energetic Electrons Driven by Ducted and Nonducted Chorus Waves

Geophysical Research Letters
Bursts of electron butterfly distributions at 10s keV correlated with chorus waves are frequently observed in the Earth's magnetosphere. Strictly ducted (parallel) upper‐band chorus waves are proposed to cause them by nonlinear cyclotron trapping ...

Observational Analysis on the Relationship Between Chorus Waves and MeV Microburst Electron Precipitation

Geophysical Research Letters
Microbursts are thought to be a key contributor to radiation belt electron loss, with chorus waves considered a primary driver of this precipitation. However, the conditions under which chorus waves produce MeV electron loss remain poorly constrained ...

A Theoretical Framework of Chorus Wave Excitation [PDF]

Journal of Geophysical Research: Space Physics, 2022
AbstractWe propose a self‐consistent theoretical framework of chorus wave excitation, which describes the evolution of the whistler fluctuation spectrum as well as the suprathermal electron distribution function. The renormalized hot electron response is cast in the form of a Dyson‐like equation, which then leads to evolution equations for nonlinear ...

A “Trap‐Release‐Amplify” Model of Chorus Waves [PDF]

Journal of Geophysical Research: Space Physics, 2021
AbstractWhistler mode chorus waves are quasi‐coherent electromagnetic emissions with frequency chirping. Various models have been proposed to understand the chirping mechanism, which is a long‐standing problem in space plasmas. Based on analysis of effective wave growth rate and electron phase space dynamics in a self‐consistent particle simulation, we

Modeling the wave normal distribution of chorus waves [PDF]

Journal of Geophysical Research: Space Physics, 2013
The propagation and attenuation characteristics of lower band and upper band chorus waves are investigated by ray tracing, and the evaluation of Landau damping based on an empirical suprathermal electron model derived from Time History of Events and Macroscale Interactions during Substorms (THEMIS) data.
