Precipitation of radiation belt electrons by magnetospherically reflected whistlers [PDF]

Journal of Geophysical Research: Space Physics, 1994
We use a test particle simulation model based on gyro‐averaged equations of motion to study the influence of oblique magnetospherically reflected (MR) whistlers on the near‐loss‐cone distribution function of radiation belt electrons. We find that MR whistlers originating in lightning can resonantly interact with radiation belt electrons over a broad ...

A physical model for electron radiation belts of Saturn [PDF]

Journal of Geophysical Research: Space Physics, 2012
Radiation belts cause irreversible damages to on-board instrument materials. Studies about radiation belts can be useful for development of materials that will stand such environment. Since the 1990's, ONERA develops models of radiation belts of magnetized planets, such as the Earth or Jupiter.

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 ...

On the source location of radiation belt relativistic electrons [PDF]

Journal of Geophysical Research: Space Physics, 2000
Observations from the High Sensitivity Telescope (HIST) on Polar made around January and May 1998 are used to constrain the source location of outer radiation belt relativistic electrons. Phase space densities calculated as a function of the three adiabatic invariants show positive radial gradients for L < 4, suggestive of no source in that region ...

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.

Derivations of the Total Radiation Belt Electron Content

Journal of Geophysical Research: Space Physics
AbstractWe present multiple derivations of the Total Radiation Belt Electron Content (TRBEC), an indicator of the global number of electrons that instantaneously occupy the radiation belts. Derived from electron flux measurements, the TRBEC reduces the spatial information into a scalar quantity that concisely describes global aspects of the system ...

The Phase Space Density Evolution of Radiation Belt Electrons under the Action of Solar Wind Dynamic Pressure

Magnetochemistry, 2023
Earth’s radiation belt and ring current are donut-shaped regions of energetic and relativistic particles, trapped by the geomagnetic field. The strengthened solar wind dynamic pressure (Pdyn) can alter the structure of the geomagnetic field, which can ...

On the Formation of Trapped Electron Radiation Belts at Ganymede

Geophysical Research Letters
AbstractThis study presents evidence of stably trapped electrons at Jupiter's moon Ganymede. We model energetic electron pitch angle distributions and compare them to observations from the Galileo Energetic Particle Detector to identify signatures of trapped particles during the G28 encounter.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

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 ...
