Predictions of Auroral Electron Precipitation and Joule Heating at Uranus

Geophysical Research Letters
The precipitation of electrons and Joule heating are key processes through which energy is transferred from Uranus' magnetosphere to its upper atmosphere. These processes drive atmospheric ionization, thermospheric heating, and auroral emission at Uranus.

The evolution of electron density and temperature distributions in the topside ionosphere during magnetic storms [PDF]

The latitudinal distributions of electron density and temperature during geomagnetic storms in the mid-latitude topside ionosphere are observed to change in a manner than can be related to the evolution of ring current particle populations. The region of

Estimating Electron Precipitation using the Total Radiation Belt Electron Content

, 2022
In the near-Earth space environment charged particles, mainly electrons and protons, are heavily influenced by Earth's magnetic field and can be captured for years and more. The number of particles with trapped trajectories accumulates over time to create regions of high-intensity radiation that are known as the Van Allen radiation belts.

Decomposition process in a FeAuPd alloy nanostructured by severe plastic deformation

, 2008
The decomposition process mechanisms have been investigated in a Fe50Au25Pd25 (at.%) alloy processed by severe plastic deformation. Phases were characterized by X-ray diffraction and microstructures were observed using transmission electron microscopy ...

Precipitation kinetics of Al3Zr and Al3Sc in aluminum alloys modeled with cluster dynamics [PDF]

, 2005
Precipitation kinetics of Al3Zr and Al3Sc in aluminum supersaturated solid solutions is studied using cluster dynamics, a mesoscopic modeling technique which describes the various stages of homogeneous precipitation by a single set of rate equations. The

On the Spatial and Temporal Evolution of EMIC Wave‐Driven Relativistic Electron Precipitation: Magnetically Conjugate Observations From the Van Allen Probes and CALET

Geophysical Research Letters
Electromagnetic ion cyclotron (EMIC) waves have been shown to be able to drive strong electron precipitation, particularly at MeV energies. However, the spatio‐temporal evolution of both the waves and the resulting precipitation is still not well ...

Radiation‐Belt Dropouts: Relationship With Geomagnetic Storms and MeV Precipitation

Geophysical Research Letters
To better understand rapid radiation belt losses, this statistical study examines dropouts, defined as a phase‐space density (PSD) decrease by a factor of ≥5 within 8 hr.
