First IBEX observations of the terrestrial plasma sheet and a possible disconnection event [PDF]

, 2011
The Interstellar Boundary Explorer (IBEX) mission has recently provided the first all-sky maps of energetic neutral atoms (ENAs) emitted from the edge of the heliosphere as well as the first observations of ENAs from the Moon and from the magnetosheath ...

Entropy and plasma sheet transport [PDF]

Journal of Geophysical Research: Space Physics, 2009
This paper presents a focused review of the role of entropy in plasma sheet transport and also describes new calculations of the implications of plasma sheet entropy conservation for the case where the plasma pressure is not isotropic. For the isotropic case, the entropy varies in proportion to log[PV5/3], where P is plasma pressure and V is the volume

Northward field excursions in Saturn’s magnetotail and their relationship to magnetospheric periodicities [PDF]

, 2009
We present results from an investigation of Cassini encounters with Saturn’s magnetotail current sheet, using magnetic field and plasma data. In the first of two intervals shown, small periodic changes in the north-south component of the magnetic field ...

Substorm observations in the early morning sector with Equator-S and Geotail [PDF]

Annales Geophysicae, 1999
Data from Equator-S and Geotail are used to study the dynamics of the plasma sheet observed during a substorm with multiple intensifications on 25 April 1998, when both spacecraft were located in the early morning sector (03–04 MLT) at a radial ...

The correlations of energetic electron fluxes in the Earth’s central plasma sheet with solar wind variables and geomagnetic indices

Frontiers in Astronomy and Space Sciences
Correlations between the electron fluxes in the Earth’s central plasma sheet and various solar wind and magnetospheric parameters are studied. Higher-energy fluxes (above approximately 2 keV) are the focus of the analysis.

Guided waves in the plasma sheet and triggering of a substorm [PDF]

Annales Geophysicae, 1994
A guided propagation of magnetoacoustic wave in the plasma sheet located between two lobes of the magnetotail is investigated. The dispersion equation for the wave and equation connecting a disturbance of plasma pressure inside the plasma sheet and ...

Particle acceleration in axisymmetric pulsar current sheets

, 2015
The equatorial current sheet in pulsar magnetospheres is often regarded as an ideal site for particle acceleration via relativistic reconnection. Using 2D spherical particle-in-cell simulations, we investigate particle acceleration in the axisymmetric ...

Thinning and expansion of the substorm plasma sheet: Cluster PEACE timing analysis [PDF]

Annales Geophysicae, 2004
The storage and subsequent removal of magnetic flux in the magnetotail during a geomagnetic substorm has a dramatic effect on the thickness of the cross-tail plasma sheet. The near-Earth plasma sheet is thought to thin during the growth phase and then

Energy limits of electron acceleration in the plasma sheet during substorms: A case study with the Magnetospheric Multiscale (MMS) mission

Geophysical Research Letters, 2016
We present multipoint observations of earthward moving dipolarization fronts and energetic particle injections from NASA's Magnetospheric Multiscale mission with a focus on electron acceleration.

Spatial variation of eddy-diffusion coefficients in the turbulent plasma sheet during substorms [PDF]

Annales Geophysicae, 2009
Study of the plasma turbulence in the central plasma sheet was performed using the Interball-Tail satellite data. Fluctuations of the plasma bulk velocity in the plasma sheet were deduced from the measurements taken by the Corall instrument for ...
