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 ...

Nonlinear wave propagation and reconnection at magnetic X-points in the Hall MHD regime [PDF]

, 2012
Context: The highly dynamical, complex nature of the solar atmosphere naturally implies the presence of waves in a topologically varied magnetic environment.

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.

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.

Topology of turbulence within collisionless plasma reconnection

Scientific Reports, 2023
In near-collisionless plasmas, which are ubiquitous in astrophysics, entropy production relies on fully-nonlinear processes such as turbulence and reconnection, which lead to particle acceleration.

The role of three-dimensional transport in driving enhanced electron acceleration during magnetic reconnection [PDF]

, 2017
Magnetic reconnection is an important driver of energetic particles in many astrophysical phenomena. Using kinetic particle-in-cell simulations, we explore the impact of three-dimensional reconnection dynamics on the efficiency of particle acceleration ...

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.

Reconnection of magnetic flux ropes driven by two-color Laguerre–Gaussian laser pulses in plasma

Matter and Radiation at Extremes
The generation and reconnection of magnetic flux ropes in a plasma irradiated by two Laguerre–Gaussian laser pulses with different frequencies and opposite topological charges are investigated numerically by particle-in-cell simulations. It is shown that

Recent Progress in Understanding Solar Magnetic Reconnection [PDF]

Journal of Astronomy and Space Sciences, 2015
Magnetic reconnection is a fundamental process occurring in a wide range of astrophysical, heliospheric and laboratory plasmas. This process alters magnetic topology and triggers rapid conversion of magnetic energy into thermal heating and nonthermal ...
