Global Circulation of Martian Ionospheric Currents Revealed by Magnetometer Data

open access: yesAGU Advances, Volume 7, Issue 6, September 2026.
Abstract In the dynamo region of the Martian ionosphere, a large‐scale current is generated by charge separation: ions collide with neutrals while electrons preferentially gyrate around local magnetic field lines. Using MAVEN magnetometer data and a physics‐informed neural network constrained by Ampère's law and Gauss's law for magnetism (the Neural ...

Extreme Radiation Belt Dropout During the May 2024 Superstorm

open access: yesAGU Advances, Volume 7, Issue 6, September 2026.
Abstract The geomagnetic superstorm in May 2024 represents the most extreme space weather event over the past two decades, offering a unique opportunity to investigate radiation belt electron dynamics under exceptionally strong solar wind driving conditions. Observations from the Arase satellite show that relativistic electron fluxes dropped by several

Averaged Resistive MHD Equations

open access: yes, 1993
Averaged resistive MHD equations are derived by using the Lagrangian formalism. The assumption is that the perturbation is of single toroidal harmonics on the special magnetic coordinates Jacobian of which is independent of the toroidal angle.

Sensitivity of the Martian Magnetotail to Model Configuration Choices in Multispecies MHD Simulations

open access: yesEarth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Numerical modeling has been a key component in the study of the Mars space environment, providing a comprehensive global representation that is not always easy to obtain in spacecraft measurements. However, there are inconsistencies in data‐model and model‐model comparisons, regardless of whether the simulation conditions are identical or ...

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

open access: yesJournal 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
