Generation of Realistic Short Chorus Wave Packets

open access: yesGeophysical Research Letters, 2021
AbstractMost lower‐band chorus waves observed in the inner magnetosphere propagate under the form of moderately intense short wave packets with fast frequency and phase variations. Therefore, understanding the formation mechanism of such short wave packets is crucial for accurately modeling electron nonlinear acceleration or precipitation into the ...

Origin of two-band chorus in the radiation belt of Earth

open access: yesNature Communications, 2019
Chorus waves are crucial on radiation belt dynamics in the space of magnetized planets. Here, the authors show that initially excited single-band chorus waves can quickly accelerate medium energy electrons, and divide the anisotropic electrons into low ...

Backward-propagating source as a component of rising tone whistler-mode chorus generation

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Whistler-mode chorus waves in the magnetosphere play a crucial role in space weather via wave–particle interactions. The past two decades have observed tremendous advances in theory and simulations of chorus generation; however, several details of the ...

Plasmaspheric High‐Frequency Whistlers as a Candidate Cause of Shock Aurora at Earth

open access: yesGeophysical Research Letters, 2023
Auroral brightening driven by interplanetary shocks on Earth's closed magnetic field lines is commonly attributed to the 0.1–10 keV electron precipitations by electron cyclotron harmonic waves and whistler‐mode chorus waves in the low‐density region.

Electron acceleration at Jupiter: input from cyclotron-resonant interaction with whistler-mode chorus waves [PDF]

open access: yesAnnales Geophysicae, 2013
Jupiter has the most intense radiation belts of all the outer planets. It is not yet known how electrons can be accelerated to energies of 10 MeV or more.

Relativistic Landau resonances [PDF]

open access: yes, 2005
The possible interactions between plasma waves and relativistic charged particles are considered. An electromagnetic perturbation in the plasma is formulated as an elliptically polarized wave, and the collisionless plasma is described by a distribution ...

Relativistic Microburst Scale Size Induced by a Single Point‐Source Chorus Element

open access: yesGeophysical Research Letters, 2022
Relativistic microbursts are impulsive, sub‐second precipitation bursts of relativistic electrons. They are one of the main loss mechanisms of outer radiation belt electrons, and are driven by chorus waves.

Repetitive Emissions of Rising‐Tone Chorus Waves in the Inner Magnetosphere [PDF]

open access: yesGeophysical Research Letters, 2020
Abstract Chorus waves in the inner magnetospheres of the Earth and other magnetized planets typically occur in the form of discrete and repetitive quasi‐monochromatic emissions with a frequency chirping, which was discovered more than 50 years ago. However, until now there is still no satisfactory explanations for

Nonlinear Coupling Between Whistler‐Mode Chorus and Electron Cyclotron Harmonic Waves in the Magnetosphere

open access: yesGeophysical Research Letters, 2018
Electromagnetic whistler‐mode chorus and electrostatic electron cyclotron harmonic (ECH) waves can contribute significantly to auroral electron precipitation and radiation belt electron acceleration.

Fine structure of large‐amplitude chorus wave packets

open access: yesGeophysical Research Letters, 2014
AbstractWhistler mode chorus waves in the outer Van Allen belt can have consequences for acceleration of relativistic electrons through wave‐particle interactions. New multicomponent waveform measurements have been collected by the Van Allen Probes Electric and Magnetic Field Instrument Suite and Integrated Science's Waves instrument.
