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,

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 ...

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.

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 ...

Multiple time-scale beats in aurora: precise orchestration via magnetospheric chorus waves. [PDF]
Sci Rep, 2020 AbstractThe brightness of aurorae in Earth’s polar region often beats with periods ranging from sub-second to a few tens of a second. Past observations showed that the beat of the aurora is composed of a superposition of two independent periodicities that co-exist hierarchically.

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.

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

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
