On How High-Latitude Chorus Waves Tip the Balance Between Acceleration and Loss of Relativistic Electrons [PDF]
Geophysical Research Letters, 2019 Modeling and observations have shown that energy diffusion by chorus waves is an important source of acceleration of electrons to relativistic energies.

Electron Microbursts Induced by Nonducted Chorus Waves [PDF]
Frontiers in Astronomy and Space Sciences, 2021 Microbursts, short-lived but intense electron precipitation observed by low-Earth-orbiting satellites, may contribute significantly to the losses of energetic electrons in the outer radiation belt. Their origin is likely due to whistler mode chorus waves,

Whistler-mode chorus waves at Mars. [PDF]
Nat Commun, 2023 AbstractChorus waves are naturally occurring electromagnetic emissions in space and are known to produce highly energetic electrons in the hazardous radiation belt. The characteristic feature of chorus is its fast frequency chirping, whose mechanism remains a long-standing problem.

Space Weather, 2023 Whistler‐mode chorus waves play an essential role in the acceleration and loss of energetic electrons in the Earth’s inner magnetosphere, with the more intense waves producing the most dramatic effects. However, it is challenging to predict the amplitude

Characteristics of magnetospherically reflected chorus waves observed by CLUSTER [PDF]
Annales Geophysicae, 2004 Chorus emissions are often observed by the STAFF spectrum analyser on board the 4 satellites of CLUSTER. This instrument provides the cross spectral matrix of three magnetic and two electric field components. Dedicated software processes this spectral

Intense chorus waves are the cause of flux-limiting in the heart of the outer radiation belt [PDF]
Scientific Reports, 2022 Chorus waves play a key role in outer Van Allen electron belt dynamics through cyclotron resonance. Here, we use Van Allen Probes data to reveal a new and distinct population of intense chorus waves excited in the heart of the radiation belt during the ...

Detection of ultrafast electron energization by whistler-mode chorus waves in the magnetosphere of Earth [PDF]
Scientific ReportsElectromagnetic whistler-mode chorus waves are a key driver of variations in energetic electron fluxes in the Earth’s magnetosphere through the wave-particle interaction.

Geophysical Research Letters, 2016 Plasma kinetic theory predicts that a sufficiently anisotropic electron distribution will excite whistler mode waves, which in turn relax the electron distribution in such a way as to create an upper bound on the relaxed electron anisotropy.

Nonlinear Wave Growth Analysis of Chorus Emissions Modulated by ULF Waves
Geophysical Research Letters, 2022 AbstractWe present Van Allen Probes observations of periodic chorus wave emissions in the troughs of compressional ultralow frequency (ULF) waves. During this event, the spectral gap of chorus waves gradually widens as the spacecraft moves from the equatorial source region towards higher latitudes.

Diffuse auroral precipitation driven by lower-band chorus second harmonics [PDF]
Nature Communications, 2023 Scattering by the upper- and lower-band chorus waves are the dominant cause of diffuse auroral precipitation. Here, the authors show that the lower-band chorus alone satisfies the preferred condition for the generation of second harmonics to trigger the ...
