Modelling the outer radiation belt as a complex system in a self-organised critical state [PDF]

, 2005
The dynamic behaviour of the outer electron radiation belt makes this area of geo-space a candidate for the concept of self-organized criticality. It is shown here that frequency distributions of measured outer electron radiation belt data are well ...

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.

Optical Signatures of the Outer Radiation Belt Boundary

Geophysical Research Letters, 2019
We present observations that show structured diffuse aurora (SDA) correlated with electron precipitation directly from the outer boundary of the outer radiation belt.

Processes in auroral oval and outer electron radiation belt

Earth, Planets and Space, 2018
We have analyzed the role of auroral processes in the formation of the outer radiation belt, considering that the main part of the auroral oval maps to the outer part of the ring current, instead of the plasma sheet as is commonly postulated.

Relative positions of the polar boundary of the outer electron radiation belt and the equatorial boundary of the auroral oval [PDF]

Annales Geophysicae, 2018
Finding the position of the polar boundary of the outer electron radiation belt, relative to the position of the auroral oval, is a long-standing problem.

Energetic particle precipitation into the middle atmosphere triggered by a coronal mass ejection [PDF]

, 2007
Precipitation of relativistic electrons into the atmosphere has been suggested as the primary loss mechanism for radiation belt electrons during large geomagnetic storms.

Research advances in the data assimilative modeling of the Earth's radiation belt electrons

地球与行星物理论评
The Earth's radiation belts are regions where high-energy charged particles congregate in near-Earth space. Given that high-energy particles in the radiation belts pose a severe threat to the safety of spacecraft in orbit and astronauts, it is of vital ...

Resonant Scattering of Radiation Belt Electrons at Saturn by Ion Cyclotron Waves

Geophysical Research Letters, 2023
By constructing an empirical model of the spectral and latitudinal distribution of ion cyclotron waves on the basis of Cassini datasets, we investigate the resonant interactions between ion cyclotron waves and radiation belt electrons at Saturn ...

Discovery of a transient radiation belt at Saturn [PDF]

, 2008
Radiation belts have been detected in situ at five planets. Only at Earth however has any variability in their intensity been heretofore observed, in indirect response to solar eruptions and high altitude nuclear explosions. The Cassini spacecraft's MIMI/

Association of radiation belt electron enhancements with earthward penetration of Pc5 ULF waves: a case study of intense 2001 magnetic storms [PDF]

Annales Geophysicae, 2015
Geospace magnetic storms, driven by the solar wind, are associated with increases or decreases in the fluxes of relativistic electrons in the outer radiation belt.
