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.

Aspects of three-dimensional MHD : magnetic reconnection and rotating coronae

, 2010
Solutions of the magnetohydrodynamic (MHD) equations are very important for modelling laboratory, space and astrophysical plasmas, for example the solar and stellar coronae, as well as for modelling many of the dynamic processes that occur in these ...

Dayside and nightside reconnection rates inferred from IMAGE FUV and Super Dual Auroral Radar Network data [PDF]

, 2006
peer reviewedThe spectrographic imager at 121.8 nm ( SI12) of the far ultraviolet ( FUV) experiment onboard the IMAGE spacecraft produces global images of the Doppler- shifted Lyman alpha emission of the proton aurora.

Plasma Stability in Turbulent Magnetic Flux Ropes Downstream of a Collisionless Shock

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract How pre‐existing solar wind turbulence, and coherent structures such as magnetic flux ropes within it, influence the transition of plasma across a shock is still poorly understood. Recently, in situ observations from the Earth's magnetosheath have been used to study plasma stability against ion kinetic instabilities. In the turbulent flow, the

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.

Topological Point Defects in SmC* Liquid Crystals Under Mechanical Disturbance

Advanced Materials Interfaces, Volume 13, Issue 11, 9 June 2026.
Tangetial air jet shear inducess island formation and nucleates topological point defects in uniform SmC films. Island bounded by edge dislocation loops shrink and transform into isolated point defects under continued shear. Mechanical perturbatio provides a controllable route for defect engineering in smectric liquid crystal thin films.

Association of Pi2 pulsations and pulsed reconnection: Ground and Cluster observations in the tail lobe at 16 RE [PDF]

, 2006
International audienceSimultaneous measurements from the Cluster spacecraft and several ground stations (SAMNET, IMAGE, Kakioka, Hermanus) provide evidence for an association of Pi2 pulsations and pulsed reconnection in the magnetotail.

Electrophysiological Characteristics of Atrial Fibrillation Trigger Sites During Ongoing Atrial Fibrillation Using Ultra‐High‐Resolution Mapping

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
AF trigger sites exhibited a markedly shorter minimum local cycle length during ongoing AF, suggesting transient rapid activity. Ultra‐high‐resolution mapping during ongoing AF may provide complementary mechanistic information when conventional trigger mapping is inconclusive.
