Heliospheric plasma sheets [PDF]

Journal of Geophysical Research: Space Physics, 2004
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 data from 1995 reveals that only half concur with both high‐beta plasma and current sheets, as required

RCM modeling of bubble injections into the inner magnetosphere: geosynchronous orbit and the ionospheric responses

Frontiers in Astronomy and Space Sciences, 2023
Introduction: Accurate characterization of the plasma sheet source population in the ring current region and its outer boundary at geosynchronous orbit is crucial for understanding the dynamics of the Earth’s magnetosphere.

Magnetic Turbulence Associated with Magnetic Dipolarizations in the Near-Tail of the Earth’s Magnetosphere: Test of Anisotropy [PDF]

Journal of Astronomy and Space Sciences, 2011
In this paper, the anisotropic nature of the magnetic turbulence associated with magnetic dipolarizations in the Earth’s plasma sheet is examined. Specifically, we determine the power spectral indices for the perpendicular and parallel components of ...

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.

Improvement of Plasma Sheet Neural Network Accuracy With Inclusion of Physical Information

Frontiers in Astronomy and Space Sciences, 2020
The near-Earth plasma sheet is the source for electrons in the inner magnetosphere. The coupling between the solar wind and the near-Earth plasma sheet is dominated by non-linear processes, making any relationship difficult to infer.

Magnetohydrodynamic Turbulence in the Earth’s Magnetotail From Observations and Global MHD Simulations

Frontiers in Astronomy and Space Sciences, 2021
Magnetohydrodynamic (MHD) turbulent flows are found in the solar wind, the magnetosheath and the magnetotail plasma sheet. In this paper, we review both observational and theoretical evidence for turbulent flow in the magnetotail.

Modeling and Prediction of Near-Earth Plasma Sheet Parameters Using the Rice Convection Model and the Recurrent Neural Network

Frontiers in Astronomy and Space Sciences, 2021
Interaction between Earth’s magnetotail and its inner magnetosphere plays an important role in the transport of mass and energy in the ionosphere–magnetosphere coupled system.

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.

New Results From Galileo's First Flyby of Ganymede: Reconnection‐Driven Flows at the Low‐Latitude Magnetopause Boundary, Crossing the Cusp, and Icy Ionospheric Escape

Geophysical Research Letters, 2018
On 27 June 1996, the NASA Galileo spacecraft made humanity's first flyby of Jupiter's largest moon, Ganymede, discovering that it is the only moon known to possess an internally generated magnetic field. Resurrecting the original Galileo Plasma Subsystem

SIMULATION STUDY OF THE ENERGETIC NEUTRAL ATOM (ENA) IMAGING MONITORING OF THE GEOMAGNETOSPHERE ON A LUNAR BASE

Solar-Terrestrial Physics, 2021
Since the moon’s revolution cycle is exactly the same as its rotation cycle, we can only see the moon always facing Earth in the same direction. Based on the clean particle radiation environment of the moon, a neutral atomic telemetry base station could ...
