Dipolarization Regions in Mercury's Magnetosphere: Observation of Flux Pileup and Formation of a Substorm Current Wedge

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract At the end of its mission, the MESSENGER spacecraft's orbit intersected Mercury's nightside magnetic equator at low altitudes below 420 km, enabling the first in situ observations of this region, where the magnetic field strength is typically sub‐dipolar.

The Dominant Role of Crustal Fields in Structuring Electromagnetic Environment Within the Martian Dayside Magnetosphere

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Although Mars lacks an intrinsic global dipole magnetic field, the existence of crustal magnetic anomalies in the southern hemisphere causes the Martian magnetosphere to have the hybrid characteristics combining Venus‐like induced and Earth‐like intrinsic types.

Modulation of Electron Rolling‐Pin Distribution Behind Anti‐Dipolarization Front

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract The electron rolling pin distribution, showing electron pitch angles primarily at 0°, 90°, and 180°, has been recently observed behind dipolarization fronts (DFs) in the magnetosphere of Earth. However, the relation between such distribution and the leading edge of tailward magnetic reconnection jets, also known as anti‐dipolarization fronts ...

MMS Observations of a Compressed, Strongly Driven Magnetopause During the 2024 Mother's Day Storm

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract From 10 to 12 May 2024, a series of coronal mass ejections led to one of the strongest geomagnetic storms of the century, referred to as the Mother's Day or Gannon Storm. MMS's position on the dayside magnetosphere on 11 May provided observations of a strongly driven and compressed ∼7RE $\left(\sim 7\ {R}_{E}\right)$ reconnecting magnetopause.

Detection of High‐Latitude Magnetic Reconnection Between the Northward Interplanetary Magnetic Field and a Closed Magnetic Field Wedge Linked to a Transpolar Arc

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Transpolar arcs (TPAs) describe a subset of auroral emissions observed poleward of the Earth's main auroral ovals when the interplanetary magnetic field (IMF) is northward. These emissions are thought to align with a “wedge” of closed magnetic field lines extending to the high‐latitude boundary of the Earth's magnetosphere, where they are ...

Recent advances in the magnetic reconnection, dipolarization, and auroral processes at giant planets from the perspective of comparative planetology

Earth and Planetary Physics
Magnetic reconnection and dipolarization are crucial processes driving magnetospheric dynamics, including particle energization, mass circulation, and auroral processes, among others.

Unraveling Jupiter's Enigmatic Ionosphere: Evidence of Magnetically‐Controlled Wind‐Driven Dynamics

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract This study investigates the non‐solar trends and variability in Jupiter's sub‐auroral ionosphere from Pioneer, Voyager, Galileo, and Juno radio occultation electron density profiles. We show that these data are correlated with magnetic field geometry via primarily westward and equatorward thermospheric neutral winds driving field‐aligned ...
