Wave-induced loss of ultra-relativistic electrons in the Van Allen radiation belts [PDF]

open access: yesNature Communications, 2016
The processes that lead to losses of highly energetic particles from Earth’s radiation belts remain poorly understood. Here the authors compare observations and models of a 2013 event to show that electromagnetic ioncyclotron waves provide the dominant ...

Discovery and insights from DSX mission’s high-power VLF wave transmission experiments in the radiation belts [PDF]

open access: yesScientific Reports, 2022
Space weather phenomena can threaten space technologies. A hazard among these is the population of relativistic electrons in the Van Allen radiation belts.

CORONAL RADIATION BELTS [PDF]

open access: yesThe Astrophysical Journal, 2009
The magnetic field of the solar corona has a large-scale dipole character, which maps into the bipolar field in the solar wind. Using standard representations of the coronal field, we show that high-energy ions can be trapped stably in these large-scale closed fields.

Formation of electron radiation belts at Saturn by Z-mode wave acceleration [PDF]

open access: yesNature Communications, 2018
Radial diffusion is the only mechanism considered to accelerate trapped electrons to relativistic energies in Saturn’s magnetic field, forming radiation belts.

Ganymede's Radiation Cavity and Radiation Belts

open access: yesGeophysical Research Letters, 2022
While planetary radiation belts are all embedded within the low energy solar wind, Ganymede is in the unique situation of being surrounded by the energetic particles of Jupiter's magnetosphere.

Relativistic surfatron process for Landau resonant electrons in radiation belts [PDF]

open access: yesNonlinear Processes in Geophysics, 2014
Recent theoretical studies of the nonlinear wave-particle interactions for relativistic particles have shown that Landau resonant orbits could be efficiently accelerated along the mean background magnetic field for propagation angles θ in close proximity

What effect do substorms have on the content of the radiation belts? [PDF]

open access: yesJ Geophys Res Space Phys, 2016
Substorms are fundamental and dynamic processes in the magnetosphere, converting captured solar wind magnetic energy into plasma energy. These substorms have been suggested to be a key driver of energetic electron enhancements in the outer radiation ...

Radial Transport in the Earth’s Radiation Belts: Linear, Quasi-linear, and Higher-order Processes

open access: yesThe Astrophysical Journal Supplement Series, 2023
Observational studies of the Earth’s radiation belts indicate that Alfvénic fluctuations in the frequency range of 2–25 mHz accelerate electrons to relativistic energies.

Reconstruction of the Radiation Belts for Solar Cycles 17–24 (1933–2017)

open access: yesSpace Weather, 2021
We present a reconstruction of the dynamics of the radiation belts from solar cycles 17 to 24 which allows us to study how radiation belt activity has varied between the different solar cycles.
