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

The 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.

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

OMEP-EOR: A MeV proton flux specification model for electric orbit raising missions
Journal of Space Weather and Space Climate, 2021 Electric Orbit Raising (EOR) for telecommunication satellites significantly reduced on-board fuel mass at the price of extended transfer durations. These relatively long transfers, which usually span a few months, cross large spans of the radiation belts,
