First Observation of Electron Rolling‐Pin Distribution in Jupiter's Magnetosphere

Geophysical Research Letters
The electron rolling‐pin distribution, showing electron pitch angles primarily at 0°, 90°, and 180°, has been widely studied in the Earth's magnetosphere, but has never been reported in other planetary environments.

Convective Amplification of Ionospheric Feedback by a Finite‐Duration Inertial Alfvén‐Wave Source

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract We investigate the ionospheric feedback instability (IFI) driven by a finite‐duration localized source of inertial Alfvén waves. Wave‐excited conductance perturbations undergo Pedersen mobility drift in the convection and wave electric fields and are amplified.

Local Generation of Plasmaspheric Plume Hiss

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The statistical analysis of hiss waves observed in the plasmaspheric plume (Wu et al., 2026, https://doi.org/10.1029/2026gl121667) is significant for identifying nonlinear wave growth processes in the equatorial region. Because nonlinear growth rates greatly exceed linear growth rates, they enable the local generation of new wave packets in ...

Quasi‐Homologous Solar Flares and Impacts on Thermospheric Density and Satellite Orbital Drag

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Quasi‐Homologous Flaring (QHF) activity from active regions on the Sun releases intense electromagnetic radiation in recurrent bursts over extended periods. In this letter, we present the effects of recurrent impulsive extreme ultraviolet (EUV) heating on thermospheric neutral density and the resulting atmospheric drag on satellites based on ...

Transport of Mirror Mode Structures through Saturn’s Magnetopause Reconnection

The Astrophysical Journal
Magnetopause reconnection plays a significant role in transferring plasma and energy from the solar wind to planetary magnetospheres. Using a Cassini measurement, we reported a magnetopause reconnection at Saturn, identified by the Hall magnetic field ...

Quantifying Non‐Maxwellian Properties of Ion Populations During Reconnection at Earth's Magnetopause

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract We investigate ion velocity‐space features within the exhaust of magnetopause reconnection using a global hybrid‐Vlasov simulation. The Hermite transform and Gaussian Mixture Model (GMM) are applied to quantify the complexity of velocity‐space structures that arise during the mixing of magnetospheric and magnetosheath ion populations.

Analysis of Ion Cyclotron Waves during Cassini’s Flybys of Enceladus

The Astrophysical Journal
Ion cyclotron waves (ICWs) are ubiquitous phenomena within Saturn’s magnetosphere, particularly in the vicinity of Enceladus. This study focuses on the Cassini spacecraft’s flyby data of Enceladus to investigate the spatial distribution and properties of

A summary of observational records on periodicities above the rotational period in the Jovian magnetosphere [PDF]

Annales Geophysicae, 2009
The Jovian magnetosphere is a very dynamic system. The plasma mass-loading from the moon Io and the fast planetary rotation lead to regular release of mass from the Jovian magnetosphere and to a change of the magnetic topology.

Cosmogenic 10Be as a Tracer for Recent Heliospheric Encounters With Interstellar Cold Clouds and Nearby Supernovae

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Recent works suggest there are periods when the Sun encountered massive interstellar cold clouds which compressed the heliosphere to within Earth's orbit, exposing Earth to interstellar galactic cosmic rays and energetic particles of heliospheric origin.
