Dynamics of the Magnetotail Plasma Sheet Current

open access: yesAtmosphere, 2023
Magnetospheric plasma can be investigated as a continuum by adopting magnetic field B and plasma flow u as primary parameters in the Bu paradigm or as a collection of individual particles by adopting electric field E and electrical current j as primary ...

RADIATING CURRENT SHEETS IN THE SOLAR CHROMOSPHERE [PDF]

open access: yesThe Astrophysical Journal, 2012
An MHD model of a Hydrogen plasma with flow, an energy equation, NLTE ionization and radiative cooling, and an Ohm's law with anisotropic electrical conduction and thermoelectric effects is used to self-consistently generate atmospheric layers over a $50$ km height range.

Transition from substorm growth to substorm expansion phase as observed with a radial configuration of ISTP and Cluster spacecraft [PDF]

open access: yes, 2005
International audienceTransition from the growth phase to the substorm expansion during a well-isolated substorm with a strong growth phase is investigated using a unique radial (THEMIS-like) spacecraft constellation near midnight, including the probing ...

Optimal Energy Growth in Current Sheets [PDF]

open access: yesSolar Physics, 2017
In this paper, we investigate the possibility of transient growth in the linear perturbation of current sheets. The resistive magnetohydrodynamic (MHD) operator for a background field consisting of a current sheet is non-normal, meaning that associated eigenvalues and eigenmodes can be very sensitive to perturbation. In a linear stability analysis of a

The heliospheric current sheet [PDF]

open access: yesJournal of Geophysical Research: Space Physics, 2001
The heliospheric current sheet (HCS) is the boundary between open oppositely directed magnetic field lines which commonly originate as the outward extension of the solar magnetic dipole. The dipole tilt, the rotation of the Sun, and the outward propagation of the solar wind cause peaks and valleys in the current sheet which spiral outward.

Galactic cosmic ray modulation near the heliospheric current sheet

open access: yes, 2014
Galactic cosmic rays (GCRs) are modulated by the heliospheric magnetic field (HMF) both over decadal time scales (due to long-term, global HMF variations), and over time scales of a few hours (associated with solar wind structures such as coronal mass ...

South-north asymmetry of field-aligned currents in the magnetotail observed by Cluster [PDF]

open access: yes, 2010
We statistically investigated features of the field-aligned current (FAC) distribution in plasma sheet boundary layers between 17 and 19 RE in the magnetotail using the curlometer technique to calculate the current from four-point magnetic field ...

Current Sheet Statistics in the Magnetosheath

open access: yesFrontiers in Astronomy and Space Sciences, 2020
The magnetosheath (MSH) plasma turbulence depends on the structure and properties of the bow shock (BS). Under quasi-parallel (Q||) and quasi-perpendicular (Q⊥) BS configurations the electromagnetic field and plasma quantities possess quite distinct ...

Cluster as current sheet surveyor in the magnetotail [PDF]

open access: yesAnnales Geophysicae, 2013
A novel analysis technique is presented to estimate the current sheet thickness unambiguously and directly, without associating time series data with spatial structure.

“Matreshka” model of multilayered current sheet [PDF]

open access: yesGeophysical Research Letters, 2006
Current sheets are one of the key elements of the Earth's magnetosphere, determining the magnetic energy storage and release. An analytical self‐consistent model of multicomponent thin current sheets, where the plasma consists of ions of both solar wind and ionospheric origin, is presented. The influence of the electron population is taken into account
