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.

PLASMA COMPRESSION IN MAGNETIC RECONNECTION REGIONS IN THE SOLAR CORONA [PDF]
The Astrophysical Journal, 2016 ABSTRACT It has been proposed that particles bouncing between magnetized flows converging in a reconnection region can be accelerated by the first-order Fermi mechanism. Analytical considerations of this mechanism have shown that the spectral index of accelerated particles is related to the total plasma compression within the ...

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

Terrestrial Space Weather Protection Through Human‐Produced Mass‐Loading
Space Weather, Volume 24, Issue 6, June 2026.Abstract While humans become more reliant on Earth's space environment, the potential for significant harm from severe space weather continues to grow. As structures from the sun reach Earth's magnetosphere and space environment, they deposit energy that fuels geomagnetic storms.

Magnetic Reconnection at the Earliest Stage of Solar Flux Emergence [PDF]
The Astrophysical Journal, 2018 Abstract On 2016 September 20, the Interface Region Imaging Spectrograph observed an active region during its earliest emerging phase for almost 7 hr. The Helioseismic and Magnetic Imager on board the Solar Dynamics Observatory observed continuous emergence of small-scale magnetic bipoles with a rate of ∼1016 Mx s−1.

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.Abstract The objective of the present study is to investigate solar wind‐magnetosphere‐ionosphere coupling (SWMIC) under intense external driving in terms of dayside ground magnetic disturbances. Dayside magnetic reconnection drives a region‐1 sense current system, the SWMIC current system.

The Astrophysical JournalMagnetic 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.

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.Abstract The substorm current wedge constitutes the backbone of the substorm current system. Its field‐aligned current components include an upward current in the premidnight sector and a downward current in the midnight‐morning sector, which connect the auroral ionosphere to the magnetotail.
