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

open access: yesFrontiers 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 ...

Weak Bidirectional Outflows and Flare Current Sheet in a Solar Coronal Jet Driven by the Eruption of a Minifilament

open access: yesThe Astrophysical Journal, 2023
Different from the classical emerging-flux model for solar jets, recent studies proposed that the great majority of solar coronal jets are triggered by minifilament eruptions and two magnetic reconnection processes should take place during the course ...

Observations of a Quickly Flapping Interplanetary Magnetic Reconnection Exhaust

open access: yesFrontiers in Physics, 2021
On the basis of the Petschek reconnection model and the characteristics of reconnection, hundreds of reconnection exhausts were reported in the solar wind.

The Role of Helicity in Magnetic Reconnection: 3D Numerical Simulations

open access: yes, 1999
We demonstrate that conservation of global helicity plays only a minor role in determining the nature and consequences of magnetic reconnection in the solar atmosphere.

Reconstructing the Geometry of a Hot Flow Anomaly With Bounding Jets in Magnetosheath

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract When interplanetary magnetic field discontinuities interact with planetary bow shocks, hot flow anomalies (HFAs) form in the solar wind and can extend into the magnetosheath. Here we reconstruct the three‐dimensional geometry of an HFA bounded by two jet regions in the terrestrial magnetosheath.

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

open access: yesThe 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.

Interchange Reconnection Alfven Wave Generation

open access: yes, 2014
Given recent observational results of interchange reconnection processes in the solar corona and the theoretical development of the S-Web model for the slow solar wind, we extend the analysis of the 3D MHD simulation of interchange reconnection by ...

On the nature of reconnection at a solar coronal null point above a separatrix dome [PDF]

open access: yes, 2013
Three-dimensional magnetic null points are ubiquitous in the solar corona, and in any generic mixed-polarity magnetic field. We consider magnetic reconnection at an isolated coronal null point, whose fan field lines form a dome structure.

Transient, Localized Flux Transport Revealed by Electron Microsignatures Downstream of Saturnian Moons

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract In Saturn's magnetosphere, the inward transport of magnetic flux is largely carried by localized injection flux tubes filled with warm, tenuous plasma, although their inflow speeds and spatio‐temporal properties remain poorly constrained. Here, we propose that these flux tubes can modify electron microsignatures, the small‐scale, absorption ...

Reconnection in substorms and solar flares: analogies and differences [PDF]

open access: yesAnnales Geophysicae, 2009
Magnetic reconnection is the crucial process in the release of magnetic energy associated with magnetospheric substorms and with solar flares. On the basis of three-dimensional resistive MHD simulations we investigate similarities and differences ...
