The Dynamic Response of Jovian Magnetotail Reconnection to Enhanced Solar Wind Ram Pressure

The Astrophysical Journal
In this study, we employ the Grid Agnostic Magnetohydrodynamic (MHD) for Extended Research Applications (GAMERA), a high-resolving-power, three-dimensional global MHD model, to simulate magnetotail reconnection in Jupiter's magnetosphere.

The Evolution of Hot Flow Anomalies in Martian Space Environment

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Hot Flow Anomalies (HFAs) are transient foreshock structures generated by solar wind discontinuity‐bow shock interactions, with their evolution only confirmed near Earth. Using MAVEN and Tianwen‐1 joint observations, we study the evolution of a Martian HFA event detected on 17 September 2022 (dayside by MAVEN, nightside by Tianwen‐1).

Reconnection Preferentially Accelerates Light Ions at Ganymede's Magnetopause

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Juno's flyby of Ganymede revealed ion composition in its vicinity with the Jovian Auroral Distributions Experiment–Ion (JADE‐I) instrument. Throughout this flyby, we derive species‐resolved ion density and velocity moments by decomposing the time‐of‐flight data into contributions from individual ion species using species‐dependent fits. At the

Off-equatorial Electron Trajectories in Ganymede’s Magnetosphere: Implications for a Bifurcated Ring Current Under Different Jovian Wind Conditions

The Astrophysical Journal
Ganymede, Jupiter’s largest moon, hosts a minimagnetosphere sustained by its intrinsic magnetic field and embedded in the sub-Alfvénic Jovian plasma flow, providing a unique natural laboratory for studying energetic particle behavior. By combining a test-

Global Effects of Chorus and Hiss Waves on Trapped Energetic Electrons at Jupiter

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Unlike Earth, where whistler‐mode chorus is generally observed outside the plasmasphere and hiss is predominantly confined within it, Jupiter's magnetosphere frequently hosts both wave modes simultaneously. Using Juno observations, we present a global survey of whistler‐mode waves at Jupiter, demonstrating that both chorus and hiss are ...

Current Events at Saturn: Ring–Planet Electromagnetic Coupling

The Planetary Science Journal
This study presents a synthesized analysis of in situ and ground-based observations to investigate electromagnetic coupling between Saturn and its rings. During the Cassini Grand Finale, the magnetometer detected gradients in the azimuthal magnetic field

Mercury’s plasma environment after BepiColombo’s third flyby

Communications Physics
Understanding Mercury’s magnetosphere is crucial for advancing our comprehension of how the solar wind interacts with the planetary magnetospheres. Despite previous missions, several gaps remain in our knowledge of Mercury’s plasma environment.

Statistical Distributions of Plasma Density and Pressure in the Jovian Plasma Sheet

The Astrophysical Journal
The Jovian plasma sheet is a key region of the Jovian magnetosphere populated by a mix of warm and hot plasma. It is the main channel for radial transport of mass and energy in the Jovian magnetosphere and provides a favorable environment for magnetic ...
