Numerical examination of plasmoid-induced reconnection model for solar flares: the relation between plasmoid velocity and reconnection rate

, 2008
The plasmoid-induced-reconnection model explaining solar flares based on bursty reconnection produced by an ejecting plasmoid suggests a possible relation between the ejection velocity of a plasmoid and the rate of magnetic reconnection.

Observations of Turbulent Magnetic Reconnection within a Solar Current Sheet [PDF]

The Astrophysical Journal, 2018
Abstract Magnetic reconnection is a fundamental physical process in various astrophysical, space, and laboratory environments. Many pieces of evidence for magnetic reconnection have been uncovered. However, its specific processes that could be fragmented and turbulent have been short of direct observational evidence.

First Observation of Banded Electron Cyclotron Harmonic Waves at Earth's Magnetopause

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract This letter presents the first observation of banded Electron Cyclotron Harmonic (ECH) waves by Magnetospheric Multiscale (MMS) satellites near the Earth's subsolar magnetopause. The observation shows the fundamental mode (n=1 $n=1$) and its higher harmonics (n=2 $n=2$–6), each with distinct lower and upper bands separated by a spectral gap at

A window into magnetic reconnection: IRIS observations of the consequences of reconnection during solar flares

Frontiers in Astronomy and Space Sciences, 2022
Magnetic reconnection is a dynamic process that occurs in solar flares in a tenuous and hot environment. High-cadence, high-spatial resolution spectroscopic observations with the Interface Region Imaging Spectrometer (IRIS) have provided a unique window ...

Observational Signatures of Simulated Reconnection Events in the Solar Chromosphere and Transition Region

, 2009
We present the results of numerical simulations of wave-induced magnetic reconnection in a model of the solar atmosphere. In the magnetic field geometry we study in this article, the waves, driven by a monochromatic piston and a driver taken from Hinode ...

Dynamics of the Transition corona [PDF]

, 2014
Magnetic reconnection between open and closed magnetic field in the corona is believed to play a crucial role in the corona/heliosphere coupling. At large scale, the exchange of open/closed connectivity is expected to occur in pseudo-streamer structures.

Reconstructing Magnetotail Reconnection Events Using Data Mining is Feasible and Repeatable

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Recently, Stephens et al. (2023), https://doi.org/10.1029/2022ja031066 utilized a data mining (DM) algorithm, applied to 26 years of magnetospheric magnetometer observations coupled with a flexible formulation of the magnetospheric magnetic field, to reconstruct the global configuration of the magnetotail when the Magnetospheric MultiScale ...

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

Magnetopause reconnection and interlinked flux tubes [PDF]

Annales Geophysicae, 2013
Magnetic reconnection can be a continuous or a transient process. Global magnetohydrodynamics (MHD) simulations are important tools to understand the relevant magnetic reconnection mechanisms and the resulting magnetic structures.

Intermittent reconnection and plasmoids in UV bursts in the low solar atmosphere

, 2017
Magnetic reconnection is thought to drive a wide variety of dynamic phenomena in the solar atmosphere. Yet the detailed physical mechanisms driving reconnection are difficult to discern in the remote sensing observations that are used to study the solar ...
