Magnetohydrodynamic Simulation of Forced Magnetic Reconnection [PDF]

Iranian Journal of Astronomy and Astrophysics, 2023
Magnetic reconnection is a fundamental process in laboratory, astrophysical, and space plasmas, which is a mechanism for converting magnetic energy into the thermal and kinetic energy of plasma and the efficient acceleration of charged particles.

Reconnection in a pinch

Frontiers in Astronomy and Space Sciences, 2023
A recently published analysis of current sheets has updated the classic Harris 1D static solution by considering multiple classes of charged particle trajectories in a generalized and dynamic current sheet. It uses a 1D PIC simulation to describe dynamic

The Geoeffectiveness of Solar Wind Current Sheets and Its Modulation by Foreshock Ions

Geophysical Research Letters, 2022
We examined the evolution of 34 solar wind bifurcated current sheets in the magnetosheath and their magnetospheric responses, using the in‐situ observations of the THEMIS probes and the GOES satellites.

Two Types of Martian Magnetotail Current Sheets: MAVEN Observations of Ion Composition

Geophysical Research Letters, 2023
Using measurements from the Mars Atmosphere and Volatile EvolutioN mission, we investigate the densities of H+ (nH+), O+ (nO+), and O2+ (no2+), respectively, in the Martian magnetotail current sheet.

Explosive dynamics of double tearing mode in Tokamak

Nuclear Fusion, 2023
Using the CLT code, the resistivity dependence of the reconnection rate during the explosive phase at various separations of two rational surfaces of m / n = 3/1 double tearing mode is investigated quantitatively.

FORCE BALANCE IN CURRENT SHEETS IN COLLISIONLESS PLASMA

Solar-Terrestrial Physics, 2021
In this paper, we derive a divergent form of the force balance equation for collisionless plasma in the quasineutrality approximation, in which the electric field and current density are excluded.

The thickness of current sheets and implications for coronal heating

Frontiers in Physics, 2023
The thickness of current sheets is extremely important, especially as it relates to the onset of fast magnetic reconnection. Onset determines how much magnetic free energy can build up in a field before it is explosively released.

Configuration of the Earth’s Magnetotail Current Sheet

Geophysical Research Letters, 2021
The spatial scale and intensity of Earth’s magnetotail current sheet determine the magnetotail configuration, which is critical to one of the most energetically powerful phenomena in the Earth’s magnetosphere, substorms.

On the Relation Between Jupiter's Aurora and the Dawnside Current Sheet

Geophysical Research Letters, 2023
Jupiter's auroral emission is a spectacular phenomenon that provides insight into energy release processes related to the coupling of its magnetosphere and ionosphere. This energy release is influenced by solar wind conditions.

The Stationary Electric Field in the Heliosphere and Its Possible Relation to Current Sheets

Universe, 2022
The nature of the large-scale electric field in the heliosphere is discussed in this paper. The electric potential along each line of the magnetic field should be constant in the ideally conductive solar wind.
