Natural Generation of Alfvén Waves from Three-dimensional Bursty Interchange Magnetic Reconnection in the Solar Corona

The Astrophysical Journal Letters
Alfvén waves play a significant role in solar coronal heating, solar wind acceleration, and Alfvénic turbulence formation. As a fundamental process, magnetic reconnection has long been credited as a crucial source of Alfvén waves.

Analytical solution of steady reconnection outflows in a time-varying three-dimensional reconnection model with generalized spatiotemporal distributions

Frontiers in Physics
Magnetic reconnection is a fundamental mechanism for energy conversion in the realms of space physics, astrophysics, and plasma physics. Over the past few decades, obtaining analytical solutions for three-dimensional (3D) magnetic reconnection has ...

Reconnection Onset in Overstretched Thin Current Sheets: 3‐D Kinetic Picture

Journal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.
Abstract Evolution of the magnetotail equilibrium, whose current density iso‐contours are stretched beyond the magnetic field lines due to small ion anisotropy and agyrotropic effects on the scales of the thermal ion gyroradius (the so‐called overstretched thin current sheet) is considered using 3‐D explicit particle‐in‐cell simulations.

Asymmetric distribution of reconnection jet fronts in the Jovian nightside magnetosphere [PDF]

, 2013
Magnetic reconnection plays important roles in mass transport and energy conversion in planetary magnetospheres. It is considered that transient reconnection causes localized auroral arcs or spots in the Jovian magnetosphere, by analogy to the case in ...

Global Ionospheric Responses to Four X‐Class Solar Flares in November 2025

Space Weather, Volume 24, Issue 11, November 2026.
Abstract We investigate global ionospheric responses to four X‐class solar‐disk flares that occurred in November 2025 from the same solar active region, using multi‐instrument observations including GNSS, ionosonde, geomagnetic and GOES solar irradiance data. Pronounced dayside TEC enhancements are observed for three flares (#2 X1.2, #3 X5.1, and #4 X4.

Solar Wind Control of the Martian Magnetotail Current Sheet and Magnetic Reconnection

The Astrophysical Journal
Magnetic reconnection is a rapid process that releases magnetic free energy stored in current sheets (CSs), driving various explosive phenomena throughout the Universe. In planets within the solar system, reconnection is controlled by both the solar wind

A Data‐Driven Model of the Geomagnetic Storm Recovery Phase

Space Weather, Volume 24, Issue 11, November 2026.
Abstract The recovery phase of geomagnetic storms poses a significant challenge for accurate space weather forecasting. Traditional models based on a constant decay rate fail to capture its prolonged and variable duration, leading to uncertainties in predicting impacts on technological systems.

The May 2024 Storm: The Cusps and Dayside Magnetopause in Simulated Soft X‐Rays

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The coronal mass ejection (CME) arriving at Earth on 10 May 2024 caused the most intense geomagnetic storm in the last two decades, resulting in highly unusual cusp and magnetopause dynamics. We simulate soft X‐Ray emission due to solar wind charge exchange with exospheric neutrals to image the global dayside dynamics, focusing on the impact ...
