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.

Ganymede's Radiation Cavity and Radiation Belts

Geophysical Research Letters, 2022
Abstract 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. Here we study Ganymede's environment based the recent flyby of Juno, as well as through reanalysis of past measurements from the ...

A statistical analysis of the Kappa-type energy spectrum distribution of radiation belt electrons observed by Van Allen Probes

Earth and Planetary Physics
The energy spectrum of energetic electrons is a key factor representing the dynamic variations of Earth’s Van Allen radiation belts. Increased measurements have indicated that the commonly used Maxwellian and Kappa distributions are inadequate for ...

Precipitation of Radiation Belt Electrons by EMIC Waves With Conjugated Observations of NOAA and Van Allen Satellites

Geophysical Research Letters, 2018
In this letter, we present unique conjugated satellite observations of MeV relativistic electron precipitation caused by electromagnetic ion cyclotron (EMIC) waves. On the outer boundary of the plasmasphere, the Van Allen probe observed EMIC waves.

Oscillations of the Outer Boundary of the Outer Radiation Belt During Sawtooth Oscillations [PDF]

Journal of Astronomy and Space Sciences, 2006
We report three sawtooth oscillation events observed at geosynchronous orbit where we find quasi-periodic (every 2-3 hours) sudden flux increases followed by slow flux decreases at the energy levels of ˜50-400 keV.

Isomeric Ag14 Nanoclusters With Distinct Photophysical and Nanomechanical Properties

Advanced Science, EarlyView.
Ligand‐shell isomerism in atomically precise Ag14 nanoclusters is demonstrated to regulate core distortion, photoluminescence, and mechanical properties. Subtle changes in phosphine ligand arrangement drive a pronounced emission shift from green to red and alter crystal rigidity, revealing a direct structure‐property correlation that offers new design ...

Pc5 Magnetic Pulsations during the Outer Electron Radiation Belt

International Journal of Technology, 2014
Since the discovery of the radiation belt decades ago, there still remain some fundamental questions as to which one is the mechanism responsible for the acceleration of electrons. Ground-based Pc5 magnetic pulsation during the process of increasing of 2-

The 600 keV electron injections in the Earth’s outer radiation belt: A statistical study

Earth and Planetary Physics, 2022
Relativistic electron injections are one of the mechanisms of relativistic (≥0.5 MeV) electron enhancements in the Earth’s outer radiation belt. In this study, we present a statistical observation of 600 keV electron injections in the outer radiation ...
