Influence of MHD Turbulence on Ion Kappa Distributions in the Earth's Plasma Sheet as a Function of Plasma β Parameter

Frontiers in Astronomy and Space Sciences, 2021
The possible influence of MHD turbulence on the energy distributions of ions in the Earth's plasma sheet was studied using data taken by the THEMIS satellites.

High-beta plasma blobs in the morningside plasma sheet [PDF]

Annales Geophysicae, 1999
Equator-S frequently encountered, i.e. on 30% of the orbits between 1 March and 17 April 1998, strong variations of the magnetic field strength of typically 5–15-min duration outside about 9RE during the late-night/early-morning hours.

The Role of Mesoscale Plasma Sheet Dynamics in Ring Current Formation

Frontiers in Astronomy and Space Sciences, 2021
During geomagnetically active periods ions are transported from the magnetotail into the inner magnetosphere and accelerated to energies of tens to hundreds of keV. These energetic ions, of mixed composition with the most important species being H+ and O+

Response of convection electric fields in the magnetosphere to IMF orientation change [PDF]

, 2009
[1] The transient response of convection electric fields in the inner magnetosphere to southward turning of the interplanetary magnetic field (IMF) is investigated using in‐situ electric field observations by the CRRES and Akebono spacecraft.

World-Sheet Duality, Space-Time Foam, and the Quantum Fate of a Stringy Black Hole [PDF]

, 1992
We interpret Minkowski black holes as world-sheet {\it spikes } which are related by world-sheet { \it duality} to {\it vortices } that correspond to Euclidean black holes. These world-sheet defects induce defects in the gauge fields of the corresponding

Plasma sheet expansion: Statistical characteristics [PDF]

Journal of Geophysical Research: Space Physics, 2006
The present study addresses the cause of plasma sheet expansion by statistically comparing the characteristics of lobe‐to‐plasma sheet (LB‐to‐PS) and PS‐to‐LB crossings observed by the Geotail satellite. Whereas the flapping motion of the magnetotail causes both types of crossing, the PS expansion (thinning) can be associated only with the LB‐to‐PS (PS‐

Observation of Transition Boundary between Cold, Dense and Hot, Tenuous Plasmas in the Near-Earth Magnetotail

Journal of Astronomy and Space Sciences, 2020
Properties of plasmas that constitute the plasma sheet in the near-Earth magnetotail vary according to the solar wind conditions and location in the tail. In this case study, we present multi-spacecraft observations by Cluster that show a transition of

Measurement of plasma impedance in sheet plasma.

Journal of Advanced Science, 2001
For plasma heating by the ion cyclotron resonance (ICR), we have measured the plasma impedance when a RF electric field is applied to the plasma. The minimum value of R appears near f-72kHz.

Magnetization of the plasma sheet [PDF]

Journal of Geophysical Research: Space Physics, 2004
Long‐term‐averaged three‐dimensional data‐based models were made of the −30 < x < −10, ∣y∣ < 15, ∣z∣ < 5 RE plasma sheet region. The average magnetic moments 〈μ〉 and Chew‐Goldberger‐Low (CGL) double adiabatic parameters α⊥ and α∥ were evaluated for ions and electrons.

Study of the characteristics of electron firehose unstable conditions in the terrestrial magnetotail plasma sheet

Frontiers in Physics
Electron firehose instabilities can be excited at dipolarization fronts and in the magnetic reconnection outflow in the terrestrial magnetotail, but their occurrence rate in the plasma sheet is unclear.
