Reconnection in a pinch

open access: yesFrontiers 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

open access: yesGeophysical 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

open access: yesGeophysical 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

open access: yesNuclear 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.

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

open access: yesUniverse, 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.

Characteristics of Plasma Dynamics in Current Sheets Formed in Helium Plasma

open access: yesUniverse, 2021
The characteristic features of plasma acceleration in the current sheets are discussed on the basis of an analysis of the structure of electrodynamic forces at successive stages of the evolution of the current sheets formed in the plasma with helium ions.

Comparing results of real-scale time MHD modeling with observational data for first flare M 1.9 in AR 10365

open access: yesOpen Astronomy, 2022
As shown in the first results of MHD simulations in the real scale of time, above the active region (AR) 10365, during the first flare M 1.9 (05/26/2003 05:34) at a height of 16–18 mm (lower corona), a singular line of magnetic field appears.

Heliospheric plasma sheets [PDF]

open access: yes, 2004
[1] As a high-beta feature on scales of hours or less, the heliospheric plasma sheet (HPS) encasing the heliospheric current sheet shows a high degree of variability. A study of 52 sector boundaries identified in electron pitch angle spectrograms in Wind

FORCE BALANCE IN CURRENT SHEETS IN COLLISIONLESS PLASMA

open access: yesSolar-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.

Current sheets at three-dimensional magnetic nulls:effect of compressibility [PDF]

open access: yes, 2007
The nature of current sheet formation in the vicinity of three-dimensional (3D) magnetic null points is investigated. The particular focus is upon the effect of the compressibility of the plasma on the qualitative and quantitative properties of the ...
