Detection of ultrafast electron energization by whistler-mode chorus waves in the magnetosphere of Earth [PDF]

Scientific Reports
Electromagnetic whistler-mode chorus waves are a key driver of variations in energetic electron fluxes in the Earth’s magnetosphere through the wave-particle interaction.

New chorus wave properties near the equator from Van Allen Probes wave observations

Geophysical Research Letters, 2016
The chorus wave properties are evaluated using Van Allen Probes data in the Earth's equatorial magnetosphere. Two distinct modes of lower band chorus are identified: a quasi‐parallel mode and a quasi‐electrostatic mode, whose wave normal direction is ...

Competing mechanisms of radial and local diffusion in radiation belt electron dynamics during quiet-geomagnetic conditions [PDF]

Scientific Reports
While previous investigations utilizing high-resolution satellite observations (e.g., Van Allen Probes) have elucidated the competition between radial diffusion and local wave-driven acceleration mechanisms during geomagnetic storms, the relative ...

A review of frequency chirping mechanism of chorus waves in the Earth's magnetosphere

地球与行星物理论评, 2022
Whistler mode chorus waves are common and intense electromagnetic waves in the Earth's magnetosphere. They play a crucial role in magnetospheric electron dynamics by accelerating and scattering electrons over a wide energy range.

Frequencies of wave packets of whistler-mode chorus inside its source region: a case study [PDF]

Annales Geophysicae, 2008
Whistler-mode chorus is a structured wave emission observed in the Earth's magnetosphere in a frequency range from a few hundreds of Hz to several kHz.

Observations and modeling of forward and reflected chorus waves captured by THEMIS [PDF]

Annales Geophysicae, 2011
Discrete ELF/VLF chorus emissions are the most intense electromagnetic plasma waves observed in the radiation belts of the Earth's magnetosphere. Chorus emissions, whistler-mode wave packets propagating roughly along magnetic field lines from a well ...

Verification of the backward wave oscillator model of VLF chorus generation using data from MAGION 5 satellite [PDF]

Annales Geophysicae, 2003
We present a detailed study of chorus emissions in the magnetosphere detected on board Magion 5, when the satellite was not far from the magnetic equator.

Off-equatorial effects of the nonlinear interaction of VLF chorus waves with radiation belt electrons

Frontiers in Astronomy and Space Sciences, 2022
Nonlinear processes are involved in both the growth of VLF chorus waves and the energization of radiation belt electrons trapped in the wave potential. Nonlinear theory has led to analytic formulae describing both these processes.
