Signatures of Open Magnetic Flux in Jupiter's Dawnside Magnetotail

AGU Advances
Jupiter's magnetosphere exhibits notable distinctions from the terrestrial magnetosphere. The structure and dynamics of Jupiter's dawnside magnetosphere can be characterized as a competition between internally driven sunward flow and solar wind‐driven ...

The Role of Planetary Rotation in Polar Cusp Localization

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Juno observations have revealed that Jupiter's polar cusps are displaced toward dusk and even the nightside, contradicting the Earth‐derived paradigm that is confined to narrower ranges near noon. These findings underscore the overlooked influence of planetary rotation on magnetospheric dynamics, exposing a critical gap in current theoretical ...

Nonlinear spatiotemporal signatures of whistler-mode wave activity around Mercury during six flybys of BepiColombo mission

Nature Communications
Cyclotron resonance between electromagnetic waves and plasmas may be a universal acceleration phenomenon of charged particles in magnetized planets. Coherent fine structures of whistler-mode waves serve as a signature of nonlinear resonance. However, the

Electron Dispersion at the Electron Edge of the Earth's Magnetospheric Cusp

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites (TRACERS) mission observes electron energy‐latitude dispersion at the equatorward edge of the magnetospheric cusp, and high‐cadence Analyzer for Cusp Electrons (ACE) measurements resolve the dispersed edge. The inverse velocity dispersion (low energy before high energy)

Magnetic Rope Is an Electron Selector: Discovery in Space and Conceptual Application to Medicine

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Magnetic rope is a helical structure existing ubiquitously in astrophysical and space plasmas. Such structure has been conventionally known to accelerate electrons, convert energy, and play key roles in driving solar eruptions. Here, in contrast to the conventional concept, we report that the magnetic rope can divert electrons efficiently in ...

A Survey of Magnetic Field Line Curvature in Jovian Dawn Magnetodisc

Geophysical Research Letters
The Jovian magnetosphere is highly dynamic, influenced by both solar wind and internal processes associated with the rapid planetary rotation and Io's volcanic activities.

Large‐Scale Magnetosheath Jets Formed by Shock‐Discontinuity Interactions: A Three‐Dimensional Global Hybrid Simulation

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Magnetosheath high‐speed jets with enhanced dynamic pressure are common in Earth's magnetosheath and can impinge on the magnetopause, driving pronounced boundary deformation. Recent observations indicate that shock–discontinuity interactions (SDIs) can generate magnetosheath jets, but the formation mechanism is still unclear.

The origins of patchy aurora at Jupiter

Nature Communications
Auroral emissions play a critical role in coupling the magnetosphere and atmosphere at magnetized planets. At Jupiter, isolated auroral patches equatorward of the main auroral oval have been associated with magnetospheric injections, yet the key ...

Impacts of Tidal Locking on Magnetospheric Energy Input to Exoplanet Atmospheres

The Astrophysical Journal
We investigate the effect of planetary corotation on energy dissipation within the magnetosphere–ionosphere system of exoplanets. Using magnetohydrodynamic simulations, we find that tidally locked exoplanets have a higher cross polar cap potential (CPCP)

Identification and comparative analysis of polar cusp region at Earth and the giant planets

地球与行星物理论评
The polar cusp region serves as a critical gateway for magnetosheath and solar wind plasma to enter planetary magnetospheres, playing a fundamental role in shaping solar wind-magnetosphere interactions.
