Energetic, relativistic and ultra-relativistic electrons: Comparison of long-term VERB code simulations with Van Allen Probes measurements [PDF]

, 2015
In this study, we compare long-term simulations performed by the Versatile Electron Radiation Belt (VERB) code with observations from the Magnetic Electron Ion Spectrometer and Relativistic Electron-Proton Telescope instruments on the Van Allen Probes ...

Automatic Identification of Past Radiation Belts Electron Enhancement Events Using a Ground‐Based Parameter

Earth and Space Science
We propose a new method for automatically identifying radiation belt electron enhancement events using Ca, a ground‐based 1D surrogate index for the global dynamics of the electron radiation belts.

Forecast of the Energetic Electron Environment of the Radiation Belts

Space Weather, 2022
Different modeling methodologies possess different strengths and weakness. For instance, data based models may provide superior accuracy but have a limited spatial coverage while physics based models may provide lower accuracy but provide greater spatial

Collisions and drag in debris discs with eccentric parent belts [PDF]

, 2017
Context: High-resolution images of circumstellar debris discs reveal off-centred rings that indicate past or ongoing perturbation, possibly caused by secular gravitational interaction with unseen stellar or substellar companions.

Intelligent Memory Module Overcomes Harsh Environments [PDF]

, 2008
Solar cells, integrated circuits, and sensors are essential to manned and unmanned space flight and exploration, but such systems are highly susceptible to damage from radiation.

Wave-particle interactions in the outer radiation belts [PDF]

, 2015
Data from the Van Allen Probes have provided the first extensive evidence of non-linear (as opposed to quasi-linear) wave-particle interactions in space with the associated rapid (fraction of a bounce period) electron acceleration to hundreds of keV by ...

Discovery of Diffuse Hard X-ray Emission around Jupiter with Suzaku

, 2010
We report the discovery of diffuse hard (1-5 keV) X-ray emission around Jupiter in a deep 160 ks Suzaku XIS data. The emission is distributed over ~16x8 Jovian radius and spatially associated with the radiation belts and the Io Plasma Torus.

Energetic Electron Diffusion and Precipitation Driven by Ducted Hiss Waves in High Density Irregular Region

Geophysical Research Letters
Plasmaspheric hiss plays an important role in the electron precipitation and the slot formation in radiation belts. Recent studies show the whistler‐mode waves can be guided in the density irregularities, performing parallel propagation.

Jupiter's radiation belts: Can Pioneer 10 survive? [PDF]

Model calculations of Jupiter's electron and proton radiation belts indicate that the Galilean satellites can reduce particle fluxes in certain regions of the inner magnetosphere by as much as six orders of magnitude.
