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

open access: yesThe 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 ...

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

open access: yes, 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.

Analytic solutions of the magnetic annihilation and reconnection problems. I. Planar flow profiles [PDF]

open access: yes, 1997
The phenomena of steady-state magnetic annihilation and reconnection in the vicinity of magnetic nulls are considered. It is shown that reconnective solutions can be derived by superposing the velocity and magnetic fields of simple magnetic annihilation ...

Characterising solar magnetic reconnection in confined and eruptive flares

open access: yesAstrophysics 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).

Fast plasmoid-mediated reconnection in a solar flare

open access: yesNature 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]

open access: yesAnnales 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 ...

Direct observation of high-speed plasma outflows produced by magnetic reconnection in solar impulsive events

open access: yes, 2018
Spectroscopic observations of a solar limb flare recorded by SUMER on SOHO reveal, for the first time, hot fast magnetic reconnection outflows in the corona.

Proton acceleration in analytic reconnecting current sheets [PDF]

open access: yes, 2002
Particle acceleration provides an important signature for the magnetic collapse that accompanies a solar flare. Most particle acceleration studies, however, invoke magnetic and electric field models that are analytically convenient rather than solutions ...

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

open access: yesNonlinear 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.

Signatures of magnetic reconnection at boundaries of interplanetary small-scale magnetic flux ropes

open access: yes, 2010
The interaction between interplanetary small-scale magnetic flux ropes and the magnetic field in the ambient solar wind is an important topic to understand- ing the evolution of magnetic structures in the heliosphere.
