Ion Composition and Electron Pitch Angle Variations for Interchange Events in Jupiter's Inner Magnetosphere

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract The outward transport of plasma and magnetic fluxes in the gas giant magnetospheres is balanced with a return flow of flux tubes emptied through magnetic reconnection. Evidence of interchange motions between inward and outward moving flux tubes have long been reported around Jupiter and Saturn.

Mach Number Scaling of Foreshock Magnetic Fluctuations at Quasi-parallel Bow Shocks and Their Role in Magnetospheric Driving Throughout the Solar System

The Astrophysical Journal
Upstream of quasi-parallel bow shocks, reflected ions generate ion–ion instabilities. The resulting magnetic fluctuations can advect through the shock and interact with planetary magnetospheres.

Electromagnetic Ion Cyclotron Waves in a Magnetic Reconnection Exhaust at Earth's Magnetopause

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract Plasma waves can initiate, regulate, or reflect magnetic reconnection efficiently converting magnetic energy into plasma energy. While waves ranging from below the ion cyclotron frequency to above the electron plasma frequency are commonly observed near reconnection sites, electromagnetic ion cyclotron (EMIC) waves—frequent in other plasma ...

Interactions of the magnetospheres of stars and close-in giant planets

, 2009
Since the first discovery of an extrasolar planetary system more than a decade ago, hundreds more have been discovered. Surprisingly, many of these systems harbor Jupiter-class gas giants located close to the central star, at distances of 0.1 AU or less.

KHI Development Between Inner LLBL and Magnetosphere on the Far Flanks as Observed by the MMS Mission

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract A boundary layer of finite thickness separates the magnetosheath and the magnetosphere. Within this boundary, we have the outer low‐latitude boundary layer (LLBL), the magnetopause current layer, and the inner LLBL. Earlier works point out that the interface on which Kelvin‐Helmholtz Instability (KHI) develops has implications for how ...

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.

Whistler-Langmuir oscillitons and their relation to auroral hiss [PDF]

Annales Geophysicae, 2011
A new type of oscilliton (soliton with superimposed spatial oscillations) is described which arises in plasmas if the electron cyclotron frequency Ωe is larger than the electron plasma frequency ωe, which is a typical situation for auroral ...

Laboratory Realization of Magnetopause‐Like Reconnection in Space Plasma Environment Research Facility (SPERF)

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract Magnetic reconnection explosively converts magnetic energy into plasma heating and particle acceleration. At Earth's magnetopause, reconnection governs solar wind‐magnetosphere coupling and drives global convection. Understanding these processes requires resolving reconnection's spatiotemporal evolution, which is difficult for in situ ...

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
