On the location of dayside magnetic reconnection during an interval of duskward oriented IMF [PDF]

Annales Geophysicae, 2007
We present space- and ground-based observations of the signatures of magnetic reconnection during an interval of duskward-oriented interplanetary magnetic field on 25 March 2004. In situ field and plasma measurements are drawn from the Double Star and

Theory and Applications of Non-Relativistic and Relativistic Turbulent Reconnection

, 2015
Realistic astrophysical environments are turbulent due to the extremely high Reynolds numbers. Therefore, the theories of reconnection intended for describing astrophysical reconnection should not ignore the effects of turbulence on magnetic reconnection.

Observational Evidence for Magnetic Reconnection in Solar Flares [PDF]

International Astronomical Union Colloquium, 1993
AbstractFrom studies of the magnetic topology of flaring active regions, the separator - a region were magnetic reconnection can take place - appears to be magnetically connected to places of intense chromospheric flare brightening. This suggests that magnetic reconnection occurs in the separator region in solar flares.

Deep Learning‐Based Prediction of High‐Speed Solar Wind Streams: Spatio‐Temporal Dependencies in Coronal Hole Dynamics

Earth and Space Science, Volume 13, Issue 1, January 2026.
Abstract High‐speed solar wind streams (HSS), originating from coronal holes (CH), are key drivers of space weather disturbances and heliospheric dynamics. However, forecasting HSS remains challenging due to the evolving morphology of CH. In this study, we present a deep learning‐based framework that models the spatiotemporal relationship between CH ...

The Evolution of Photospheric Magnetic Fields at the Footpoints of Reconnected Structures in the Solar Atmosphere

The Astrophysical Journal
Magnetic reconnection is believed to play an important role in the release and conversion of energy among magnetized plasma systems. So far, we have been unable to understand under what conditions magnetic reconnection can take place.

Asymmetric Magnetic Reconnection In The Solar Atmosphere

, 2013
Models of solar flares and coronal mass ejections typically predict the development of an elongated current sheet in the wake behind the rising flux rope. In reality, reconnection in these current sheets will be asymmetric along the inflow, outflow, and out-of-plane directions.

Evolution of Ionospheric Ion Upflow Flux During the April 2023 Geomagnetic Storm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract We study the impact of the evolving magnetosphere‐ionosphere‐thermosphere system on upward ion fluxes during the 23–24 April 2023 geomagnetic storm. This storm has a “double‐dip” structure where two southward IMF Bz ${\mathrm{B}}_{z}$ periods cause two dips in the SYM‐H index.

Three Types of Solar Coronal Rain during Magnetic Reconnection between Open and Closed Magnetic Structures

The Astrophysical Journal
Coronal rain (CR) is a crucial part of the mass cycle between the corona and chromosphere. It includes flare-driven CR and two types of quiescent CR, along nonflaring active region closed loops and along open structures, separately, labeled as type I ...

Theory of magnetic reconnection in solar and astrophysical plasmas [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2012
Magnetic reconnection is a fundamental process in a plasma that facilitates the release of energy stored in the magnetic field by permitting a change in the magnetic topology. In this paper, we present a review of the current state of understanding of magnetic reconnection.
