Empirical Functions for Highly Charged Ion Abundances in Solar Wind Charge Exchange Models: Addressing Post‐2011 ACE Data Limitations

open access: yesGeophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Upcoming imaging missions—NASA's LEXI and ESA/CAS's SMILE—will target solar wind charge exchange X‐ray (SWCX) emission from Earth's magnetosheath. This emission is generated by highly charged ions colliding with neutrals in Earth's exosphere.

Electrospherics and magnetospherics [PDF]

open access: yesElectrical Engineering, 1959
In the second part of a two-part article, additional experiments with small spheres of magnetic material are described. Not only are the results interesting in themselves, but also it is hoped that they may serve as analogs for such phenomena as Brownian movement, thermal movement of molecules, crystal formation, bacterial chaining, and others.

A Statistical Study of the Decreased TEC Region During Summer at Northern High Latitudes

open access: yesGeophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Based on the vertical Total Electron Content (TEC) data observed by the Global Navigation Satellite System in the northern hemisphere, a large area of low plasma density during summer at high latitudes, termed decreased TEC region, was investigated statistically between 2014 and 2024.

Two-Stream Instability as a Mechanism for Toroidal Magnetic Field Generation in the Magnetosphere of Crab Pulsar [PDF]

open access: yesarXiv, 2011
New plasma mechanism for the generation of toroidal magnetic field in the magnetosphere of Crab pulsar is presented. It is based on the development of two-stream instability in the relativistic electron-positron plasma of the pulsar magnetosphere. In particular, pulsar magnetosphere relativistic plasma is penetrated by ultrarelativistic electron beam ...

Gamma-Ray Light Curves from Pulsar Magnetospheres with Finite Conductivity [PDF]

open access: yes, 2012
We investigate the shapes of \gamma-ray pulsar light curves using 3D pulsar magnetosphere models of finite conductivity. These models, covering the entire spectrum of solutions between vacuum and force-free magnetospheres, for the first time afford mapping the GeV emission of more realistic, dissipative pulsar magnetospheres.

Shock‐induced prompt relativistic electron acceleration in the inner magnetosphere

open access: yes, 2014
We present twin Van Allen Probes spacecraft observations of the effects of a solar wind shock impacting the magnetosphere on 8 October 2013. The event provides details both of the accelerating electric fields associated with the shock and the response of

Spatial Distribution of Ion Cyclotron Waves at Io

open access: yesGeophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Ion cyclotron waves at Io are important for understanding the complex interactions between Io and Jupiter's magnetosphere. In this study, we analyze the spatial distributions of ion cyclotron waves at Io using data from seven close flybys of Io—five by Galileo and two by Juno.

Filling the Magnetospheres of Weak Pulsars [PDF]

open access: yes, 2019
Recent advances in numerical algorithms and computational power have enabled first-principles simulations of pulsar magnetospheres using Particle-in-Cell (PIC) techniques. These ab-initio simulations seem to indicate that pair creation through photon-photon collision at the light cylinder is required to sustain the pulsar engine.

The Comprehensive Inner Magnetosphere‐Ionosphere Model

open access: yes, 2014
Simulation studies of the Earth's radiation belts and ring current are very useful in understanding the acceleration, transport, and loss of energetic particles.
