Pickup Ion–Mediated Magnetic Reconnection in the Outer Heliosphere

The Astrophysical Journal Letters, 2023
Pickup ions (PUIs) play a crucial role in the heliosphere, contributing to the mediation of large-scale structures such as the distant solar wind, the heliospheric termination shock, and the heliopause.

The role of magnetic reconnection in solar activity [PDF]

, 1999
We argue that magnetic reconnection plays the determining role in many of the various manifestations of solar activity. In particular, it is the trigger mechanism for the most energetic of solar events, coronal mass ejections and eruptive flares. We propose that in order to obtain explosive eruptions, magnetic reconnection in the corona must have an ...

Kinetic Features of Alpha Particles in a Pestchek-like Magnetic Reconnection Event in the Solar Wind Observed by Solar Orbiter

The Astrophysical Journal Letters, 2023
The acceleration and heating of solar wind particles by magnetic reconnection are important mechanisms in space physics. Although alpha particles ( ^4 He ^2+ ) are the second most abundant population of solar wind ions, their kinetic behavior in solar ...

Can the Solar Wind be Driven by Magnetic Reconnection in the Sun's Magnetic Carpet? [PDF]

, 2010
The physical processes that heat the solar corona and accelerate the solar wind remain unknown after many years of study. Some have suggested that the wind is driven by waves and turbulence in open magnetic flux tubes, and others have suggested that ...

Fast plasmoid-mediated reconnection in a solar flare

Nature Communications, 2022
Solar flares provide wide range of observational details about fundamental processes involved. Here, the authors show evidence for magnetic reconnection in a strong confined solar flare displaying all four reconnection flows with plasmoids in the current

Estimates of magnetotail reconnection rate based on IMAGE FUV and EISCAT measurements [PDF]

Annales Geophysicae, 2005
Dayside merging between the interplanetary and terrestrial magnetic fields couples the solar wind electric field to the Earth's magnetosphere, increases the magnetospheric convection and results in efficient transport of solar wind energy into the ...

Cassini in situ observations of long duration magnetic reconnection in Saturn’s magnetotail [PDF]

, 2015
Magnetic reconnection is a fundamental process in solar system and astrophysical plasmas, through which stored magnetic energy associated with current sheets is converted into thermal, kinetic and wave energy1, 2, 3, 4.

Characterising solar magnetic reconnection in confined and eruptive flares

Astrophysics and Space Science, 2023
Magnetic reconnection is a fundamental mechanism through which energy stored in magnetic fields is released explosively on a massive scale, they could be presented as eruptive or confined flares, depending on their association with coronal mass ejections (CMEs).

Analytical Description of Steady Magnetic Reconnection in Hall Magnetohydrodynamics [PDF]

, 2009
Steady magnetic reconnection in the framework of incompressible Hall magnetohydrodynamics is considered. The principal role of the Hall effect in the formation of the structure of the reconnecting current sheet is emphasized.

Achieving fast reconnection in resistive MHD models via turbulent means [PDF]

Nonlinear Processes in Geophysics, 2012
Astrophysical fluids are generally turbulent and this preexisting turbulence must be taken into account for models of magnetic reconnection in astrophysical, solar or heliospheric environments.
