Observation of Turbulent Magnetohydrodynamic Cascade in the Jovian Magnetosheath

The Astrophysical Journal, 2023
We present the first estimation of the energy cascade rate in Jupiter’s magnetosheath (MS). We use in situ observations from the Jovian Auroral Distributions Experiment and the magnetometer investigation instruments on board the Juno spacecraft, in ...

Multipoint Observations of a SLAMS Evolution and Its Merger With Whistler Waves

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract We report multipoint observations of a merger between a Short Large‐Amplitude Magnetic Structure (SLAMS) and 1‐Hz whistler wave packets upstream of Earth's quasi‐parallel bow shock. Using high‐resolution data from the Magnetospheric Multiscale (MMS) mission in a string‐of‐pearls configuration, we track the SLAMS as it evolves, exhibiting ...

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 ...

Plasma Conditions Govern the Reversible Transition Between STEVE and Picket Fence Emissions

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract On 6 May 2018, a remarkable subauroral optical event exhibiting three phases of evolution (Strong Thermal Emission Velocity Enhancement [STEVE] → Picket Fence → STEVE) and co‐occurrence with a stable auroral red arc was observed over Alberta, Canada.

BepiColombo at Mercury: Three Flybys, Three Magnetospheres

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract We examine the first three BepiColombo Mercury flybys Using data from the Miniature Ion Precipitation Analyzer (MIPA), an ion mass analyzer in the Search for Exospheric Refilling and Natural Abundances package on the Mercury Planetary Orbiter designed to study magnetospheric dynamics.

Electron Energization by Ion Density Enhancement in the Martian Magnetotail—MAVEN Observations

The Astrophysical Journal
It has been long observed at Mars that electron fluxes are enhanced during the tail current sheet crossings, of which the cause is not well understood. We use a novel approach to reveal one of the electron energization mechanisms with observations from ...

Perspective on Energetic and Thermal Atmospheric Photoelectrons

Frontiers in Astronomy and Space Sciences, 2021
Atmospheric photoelectrons are central to the production of planetary ionospheres. They are created by photoionization of the neutral planetary atmosphere by solar EUV and soft X-ray irradiance.

Coupling Between Dispersive Alfvén Wave and Modified Electron Acoustic Wave in Downward Current Region: Parallel Potential Drop and Upgoing Ionospheric Electrons

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Results from a 1D kinetic simulation, for the first time, unveil the generation and time evolution of the downward parallel electric fields stemming from the coupling between modified electron acoustic waves (MEAWs) and dispersive Alfvén waves (DAWs).

Efficiency of Electromagnetic Energy Transfer From Solar Wind to Ionosphere Through Magnetospheric Ultra‐Low Frequency Waves

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Ultra‐low frequency (ULF) waves are a ubiquitous carrier of energy in geospace. However, their efficiency in transferring solar wind energy into the upper atmosphere remains a fundamental and not well‐understood question. This is due to their global presence, which cannot be fully quantified by spatially limited observations, and the need for ...

Effects of the 2018 Martian Global Dust Storm on Boundary Positions in the Induced Magnetosphere

The Planetary Science Journal
Global dust storms at Mars have a significant impact on the atmosphere and ionosphere, but only recently has their impact on the magnetosphere been investigated.
