Ray-tracing simulations of whistler-mode wave propagation in different rescaled dipole magnetic fields

Earth and Planetary Physics, 2022
Kinetic simulation is a powerful tool to study the excitation and propagation of whistler-mode waves in the Earth’s inner magnetosphere. This method typically applies a scaled-down dipole magnetic field to save computational time.

Enhancement of Dayside Westward Electrojet: Triggering Conditions and Current Closures

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Geomagnetic substorms are a major path for energy storage and release in the magnetosphere, which typically occur in the midnight sector with a strong enhancement of westward electrojets. However, by analyzing 37,940 events from a substorm list, about 3% of events unexpectedly initiated in the noon sector.

Ultra‐Low‐L Sub‐MeV Electron Microbursts During the May 2024 Super Storm

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract During the May 2024 super storm, we identified sub‐second microburst‐type relativistic electron precipitation events at McIlwain's L∼2 $L\sim 2$ in low‐Earth orbit using the Gamma‐ray Burst Monitor (CGBM) onboard the CALorimetric Electron Telescope on the International Space Station.

Cyclotron amplification of whistler-mode waves: a parametric study relevant to discrete VLF emissions in the earth's magnetosphere [PDF]

, 2002
We study the non linear amplification of VLF waves in the earth's magnetosphere. Particular attention is paid to zero order distribution functions of electrons in which there is a sharp step with respect to parallel velocity.

Magnetosphere-ionosphere coupling at Jupiter-like exoplanets with internal plasma sources: implications for detectability of auroral radio emissions [PDF]

, 2011
In this paper we provide the first consideration of magnetosphere–ionosphere coupling at Jupiter-like exoplanets with internal plasma sources such as volcanic moons.

Global-scale magnetosphere convection driven by dayside magnetic reconnection

Nature Communications
Plasma convection on a global scale is a fundamental feature of planetary magnetosphere. The Dungey cycle explains that steady-state convection within the closed part of the magnetosphere relies on magnetic reconnection in the nightside magnetospheric ...

Temporal Variations of Jupiter's Plasma Disk Observed by Juno

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract In Jupiter's magnetosphere, a key question is how plasma is transported outward from its source near Io to the distant magnetotail. Since 2016, the plasma disk has been extensively observed by the Juno mission. Using plasma data from the JADE instrument, we perform an analysis revealing significant temporal variation. For different Juno orbits,

Range finding of Alfvén oscillations and direction finding of ion-cyclotron waves by using the ground-based ULF finder [PDF]

, 1996
International audienceA new approach to the problem of direction and distance finding of magnetospheric ULF oscillations is described. It is based on additional information about the structure of geoelectromagnetic field at the Earth's surface which is ...

Latitudinal Discrepancy Between Thermospheric Density and Temperature Associated With Neutral Composition Effect

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract In this study, multi‐source thermospheric observations and TIEGCM simulations were used to explore the latitudinal variations of thermospheric temperature and total mass density at equinoxes. At nighttime, temperature and density exhibit consistent latitudinal patterns, with higher values at high latitudes.
