Achieving fast reconnection in resistive MHD models via turbulent means [PDF]

Nonlinear Processes in Geophysics, 2012
Astrophysical fluids are generally turbulent and this preexisting turbulence must be taken into account for models of magnetic reconnection in astrophysical, solar or heliospheric environments.

Fermi~I particle acceleration in converging flows mediated by magnetic reconnection

, 2012
Context. Converging flows with strong magnetic fields of different polarity can accelerate particles through magnetic reconnection. If the particle mean free path is longer than the reconnection layer is thick, but much shorter than the entire ...

Local Time Asymmetry in Energetic Electron Distribution Within Saturn's Inner Magnetosphere

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Electrons of several hundred keV in Saturn's ring current are important seed components of the radiation belt. In this study, we have statistically analyzed the spatial distribution of energetic electrons on the equatorial plane of the inner magnetosphere based on the Cassini in situ observations.

Numerical Studies of Weakly Stochastic Magnetic Reconnection [PDF]

, 2008
We study the effects of turbulence on magnetic reconnection using three-dimensional numerical simulations. This is the first attempt to test a model of fast magnetic reconnection proposed by Lazarian & Vishniac (1999), which assumes the presence of weak,

Fast magnetic reconnection in laser-produced plasma bubbles

, 2011
Recent experiments have observed magnetic reconnection in high-energy-density, laser-produced plasma bubbles, with reconnection rates observed to be much higher than can be explained by classical theory.

Evolution of Open Magnetic Flux During Substorms: The Effects of Dipole Tilt Angle

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract There is a long‐standing debate on the causes of the semiannual variation of geomagnetic activity. One of the prevailing hypotheses is that the Earth's dipole tilt angle Ψ ${\Psi }$ modulates the dayside reconnection rate, causing the so‐called equinoctial effect. Here we perform the first large‐scale statistical study to test this hypothesis.

Secondary Reconnection Between Interlinked Flux Tubes Driven by Magnetic Reconnection With a Short X‐Line

Geophysical Research Letters
A three‐dimensional particle‐in‐cell simulation is performed to study secondary reconnection between two interlinked flux tubes produced by neighboring guide field reconnection x‐lines.

Fully Kinetic Simulations of Ion‐Acoustic Waves in Asymmetric Reconnection With Cold Ions

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract In collisionless plasma, ion‐acoustic wave (IAW) is an important candidate for enhancing resistivity and viscosity, yet their presence and role in magnetic reconnection remain poorly understood. Here, we employ 2.5‐D particle‐in‐cell simulations to investigate IAWs in asymmetric magnetopause reconnection involving a cold ion population ...

Advancements in the study of collisionless magnetic reconnection and plasma waves

地球与行星物理论评
Magnetic reconnection and plasma waves share a critical connection. On the one hand, quasi-steady wave structures (shock, KAW eigenmode) play a pivotal role in the formation and structure of magnetic reconnection.

Solar Activity Dependence of the Dayside Lunar Surface Potential in the Terrestrial Magnetotail

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract On the dayside of the Moon, the surface potential is primarily determined by (a) photoelectron emission by solar radiation and (b) the ambient plasma environment. Both of these drivers have large variability, but the resulting variability of the lunar surface potential has not been fully characterized yet.
