Reconnection Rate and Transition from Ion-coupled to Electron-only Reconnection
The Astrophysical Journal, 2023 Standard collisionless magnetic reconnection couples with both electron and ion dynamics. Recently, a new type of magnetic reconnection, electron-only magnetic reconnection without ion outflow, has been observed, and its reconnection rate has been found ...

Forced Magnetic Reconnection [PDF]
Physica Scripta, 1982 By studying a simple model problem, the time evolution of magnetic field islands which are induced by perturbing the boundary surrounding an incompressible plasma with a resonant surface inside is examined. The reconnection and island formation process for sufficiently small boundary perturbations occurs on the tearing mode time scale defined by Furth,

Kinematics of relativistic magnetic reconnection [PDF]
Physical Review Letters, 1994 We study the relativistic generalizations of two-dimensional Sweet-Parker and Petschek reconnection models in the context of a relativistic pair plasma. The solutions show that if the outflow velocity from the resistive region approaches the relativistic Alfven speed, the outflow density increase from Lorentz contraction allows a much faster inflow and

Ion Loss within a Reconnection Exhaust near Mars: MAVEN Observations
The Astrophysical Journal, 2023 We present observations from Mars Atmosphere and Volatile EvolutioN of a reconnection exhaust, which was probably not ongoing, in the Martian magnetosheath. The reconnection jet with abundant heavy ions is directed outward to space.

Parker Solar Probe In Situ Observations of Magnetic Reconnection Exhausts during Encounter 1 [PDF]
Astrophysical Journal Supplement Series, 2020 Magnetic reconnection in current sheets converts magnetic energy into particle energy. The process may play an important role in the acceleration and heating of the solar wind close to the Sun.

The Astrophysical Journal, 2023 Magnetic reconnection in the lower atmosphere is a critical process in determining the chromospheric dynamics, such as Ellerman bombs and UV bursts. Because the heating of the atmosphere significantly depends on the ionization degree and plasma β , which

, 2009 We review the fundamental physics of magnetic reconnection in laboratory and space plasmas, by discussing results from theory, numerical simulations, observations from space satellites, and the recent results from laboratory plasma experiments. After a brief review of the well-known early work, we discuss representative recent experimental and ...

Kinetic Scale Magnetic Reconnection with a Turbulent Forcing: Particle-in-cell Simulations
The Astrophysical Journal, 2023 Turbulent magnetic reconnection has been observed by spacecraft to occur commonly in terrestrial magnetosphere and the solar wind, providing a new scenario of kinetic scale magnetic reconnection.

Impacts of ionospheric plasma on magnetic reconnection and Earth's magnetosphere dynamics
, 2021 Ionospheric ions (mainly H+, He+ and O+) escape from the ionosphere and populate the Earth’s magnetosphere. Their thermal energies are usually low when they first escape the ionosphere, typically a few eV to tens of eV, but are energized in their journey

Magnetic reconnection as a mechanism for energy extraction from rotating black holes [PDF]
, 2020 Spinning black holes store rotational energy that can be extracted. When a black hole is immersed in an externally supplied magnetic field, reconnection of magnetic field lines within the ergosphere can generate negative energy (relative to infinity ...
