Current sheet formation and nonideal behavior at three-dimensional magnetic null points [PDF]

, 2007
The nature of the evolution of the magnetic field, and of current sheet formation, at three-dimensional (3D) magnetic null points is investigated. A kinematic example is presented that demonstrates that for certain evolutions of a 3D null (specifically ...

Type‐III Solar Radio Bursts at Mars: A 16.5‐Year Catalog From Mars Express‐MARSIS at 0.1–5.5 MHz

Space Weather, Volume 24, Issue 10, October 2026.
Abstract The most intense radio feature in the Solar System are the solar Type‐III radio bursts, which are associated with electron beams that propagate along open magnetic field lines. Although solar radio bursts have been studied since the 1940s, observations remain mainly restricted within 1 AU.

Reconfiguration of Mercury's Exosphere During Strong Space Weather Events

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Mercury is exposed to various space weathering processes, which alter the surface and cause emission of atoms and molecules into the exosphere. The exosphere thus allows remote insights into the surface composition and erosion processes, with the emission of refractory elements such as Ca and Mg typically being dominated by micrometeoroid ...

Magnetic reconnection as the driving factor behind high-mass protostellar luminosity flares

Communications Physics
Magnetic reconnection, a critical process in astrophysical luminosity outbursts like solar flares, may also underpin such events in high-mass young stellar objects (HMYSOs).

Cross‐Scale Energy Transfer and Scale‐to‐Scale Energy Conversion During the Collisionless Magnetic Reconnection

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract This study investigates cross‐scale energy transfer (CET) and scale‐to‐scale energy conversion (SEC) during magnetic reconnection by employing the scale‐filtering approach in a particle‐in‐cell simulation. Our analysis reveals fundamentally distinct CET patterns for electrons and ions. Electron CET is primarily governed by the flow CET.

Flux-rope-mediated Turbulent Magnetic Reconnection

The Astrophysical Journal
We present a new model of magnetic reconnection in the presence of turbulence. The new model differs from the Lazarian–Vishniac turbulent reconnection theory by emphasizing the role of locally coherent magnetic structures, whose existence is shown to be ...

Magnetic Reconnection Driven by the Impact of a Magnetosheath High‐Speed Jet

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract High‐speed jets (HSJs) are transient structures in the magnetosheath characterized by enhanced dynamic pressure. While recent studies report that HSJs trigger magnetic reconnection at the magnetopause, whether they can directly drive reconnection within the magnetosheath remains an open question.

Basic Pattern of Three-dimensional Magnetic Reconnection within Strongly Turbulent Current Sheets

The Astrophysical Journal
Magnetic reconnection is a fundamental mechanism of driving eruptive phenomena of different scales and may be coupled with turbulence as suggested by recent remote-sensing and in situ observations.

IMF By‐Controlled Dawn–Dusk and Hemispheric Asymmetries of Kelvin–Helmholtz Waves and Reconnection Geometry Under Negative Dipole Tilt

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Along with magnetic reconnection, Kelvin‐Helmholtz (KH) waves are the main mechanisms controlling the solar wind‐magnetosphere interaction, enabling plasma transport into the magnetosphere due to secondary reconnection, diffusion and wave‐particle interactions.

Field‐Aligned Anisotropy of Electrons in Magnetic Hole Behind the Dipolarization Front in the Flow Braking Region

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Magnetic holes (MHs) are magnetic structures characterized by a depression of magnetic field strength and have been frequently observed around dipolarization fronts (DFs), which are characterized by the increase in the magnetic field Bz. Both MHs and DFs are potential contributors to the formation of electron anisotropy.
