Analytical Modeling of Hot Ion Interchange Injections in Saturn's Magnetosphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract Cassini's CHarge Energy Mass Spectrometer (CHEMS) instrument collected energetic plasma data from 2004 to 2017, including hundreds of observations of small‐scale nearly dispersionless “local” injection events into the inner magnetosphere. This study assesses whether these interchange‐like injections are a channel‐like structure still connected

LAPS: An MPI-parallelized 3D pseudo-spectral Hall-MHD simulation code incorporating the expanding box model

Frontiers in Astronomy and Space Sciences
Numerical simulations have been an increasingly important tool in space physics. Here, we introduce an open-source three-dimensional compressible Hall-Magnetohydrodynamic (MHD) simulation code LAPS (UCLA-Pseudo-Spectral, https://github.com/chenshihelio ...

Impacts of Neutral Wind‐Driven Currents on Geomagnetic Disturbances and Magnetospheric Dynamics During the May 2024 Storm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract The neutral wind dynamo generates ionospheric currents that can significantly affect high‐latitude electrodynamics during geomagnetic storms, yet its role in global magnetosphere‐ionosphere coupling is often underrepresented. We quantify the impact of wind‐driven currents on geomagnetic disturbances (GMDs) and magnetospheric dynamics during ...

Magnetohydrodynamic Cellular Automata

, 1990
"There has been a renewal of interest in cellular automata, partly because they give an architecture for a special purpose computer with parallel processing optimized to solve a particular problem.

Modeling Kinetic Reconnection Onset in Global Magnetospheric Simulations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract We investigate the onset of magnetic reconnection in Earth's magnetotail using a coupled magnetohydrodynamic with embedded particle‐in‐cell (MHD‐EPIC) model, which self‐consistently links global magnetospheric dynamics to electron‐scale kinetic processes. Unlike standalone kinetic simulations with idealized boundary conditions, reconnection in

Uranus's Highly Nonaxisymmetric Magnetopause and Its Impact on Magnetic Reconnection

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract Mass and energy fluxes from the solar wind can access a planet's magnetosphere through dayside magnetic reconnection. The plasma and magnetic field conditions on either side of the magnetopause determine whether reconnection is suppressed. However, magnetosheath conditions are sensitive to the shape of the magnetopause, and deviations from ...

Duality-invariant magnetohydrodynamics and dyons

, 2002
The theory of magnetohydrodynamics is extended to the cases of a plasma of separate magnetic and electric charges, as well as to a plasma of dyons, respectively. In both these cases the system possesses electric-magnetic duality symmetry. In the former

DECAF cross-device characterization of tokamak disruptions indicated by abnormalities in plasma vertical position and current

Nuclear Fusion
Abnormal (deviating from the target) variations in the plasma vertical position Z and current $I_\textrm{p}$ (such as vertical displacements, transient $I_\textrm{p}$ ‘spikes’ and quenches) constitute common elements of a disruption, a phenomenon that is

Electron‐Driven Instabilities in Jupiter's Magnetodisc

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract Thermal electrons in Jupiter's magnetodisc have been observed to be anisotropic with higher parallel temperature compared to perpendicular. In this work, we used previously‐derived electron properties (Sarkango et al., 2025, https://doi.org/10.1029/2025gl118209) to calculate electron β‖ ${\beta }_{\Vert }$ and compared the observed anisotropy ...
