Chorus Element Repetition: Roles of Energetic Electron Injection and Nonlinear Wave Growth

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Chorus waves are coherent whistler‐mode emissions in Earth’s magnetosphere and play a key role in the acceleration and loss of radiation belt electrons. Their spectra commonly consist of discrete and repetitive elements, yet the mechanism governing this repetition is not fully understood.

The Incompressible Magnetohydrodynamic Energy Cascade Rate Upstream of Mars: Effects of the Total Energy and the Cross-helicity on Solar Wind Turbulence

The Astrophysical Journal
Solar wind turbulence is a dynamical phenomenon that evolves with heliocentric distance. Orbiting Mars since 2014 September, Mars Atmosphere and Volatile EvolutioN offers a unique opportunity to explore some of its main properties beyond ∼1.38 au.

Substorm Effects on Chorus Emissions Modulated by ULF Waves

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Although cross‐scale wave‐particle interactions play a critical role in energy transfer in the magnetosphere, the influence of geomagnetic activity on the physical mechanisms involved remains unclear. In this study, we investigate this question by analyzing Van Allen Probes‐A observations of an event occurring on 25 July 2016.

The Colocation of Magnetic Reconnection and Current Disruption in Jovian Middle Magnetosphere

The Astrophysical Journal Letters
Magnetic reconnection and current disruption are two key processes in driving energy conversion and dissipation in planetary magnetospheres. At the Earth, the two processes usually occur at different locations: the current disruption process occurs more ...

New Electron Population Trapped at Low Latitudes Near Jupiter

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract We report observations of a low energy (<2 keV), trapped electron population near Jupiter's magnetic equator made by the Jovian Auroral Distributions Experiment (JADE) on Juno. Electron intensity peaks around the location of the minimum magnetic field magnitude along the field line that is connected to Juno.

Electron Energization within an Ion-scale Flux Rope Chain in Earth’s Turbulent Magnetotail Plasma Sheet

The Astrophysical Journal
Flux ropes in space plasma can play an important role in particle acceleration. However, the mechanisms of electron energization and the resulting electron energy distribution associated with flux ropes are still not fully understood. This study examines

On the Effects of the Solar Wind Structure in the Global Distribution of dBH/dt ${\text{dB}}_{H}/\text{dt}$ Spikes During Geomagnetic Storms

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract Variations in the solar wind, particularly those associated with interplanetary coronal mass ejections (ICMEs) and high‐speed streams (HSSs), drive geomagnetic disturbances that produce rapid changes in the ground magnetic field. These variations, commonly quantified by the time derivative of the horizontal magnetic field dBH/dt $\left({\text ...

The Composition of Very Energetic Heavy Ions in Jupiter’s Magnetosphere

The Astrophysical Journal
Jupiter hosts the most energetic, intense and ion-rich radiation belts in the solar system. Understanding the composition and distribution of their heavy ions is essential for constraining source, acceleration, and loss processes across an ion mass and ...

Cosmic Ray Anisotropy Generated by the June 22nd 2015 Interplanetary Events

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract On 22 June 2015, the near Earth interplanetary space was perturbed by a series of high‐speed streamers and interplanetary coronal mass ejections associated with an active region and two low‐latitude coronal holes. The interaction of these disturbances gave rise to the complex solar wind structure observed at 1 au.
