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

Europa Modifies Jupiter's Plasma Sheet

Geophysical Research Letters
Jupiter's plasma sheet has been understood to be primarily composed of Io‐genic sulfur and oxygen, along with protons at lower mass density. These ions move radially away from Jupiter, filling its magnetosphere. The material in the plasma sheet interacts

The Impact of Turbulence on Physics of the Geomagnetic Tail

Frontiers in Astronomy and Space Sciences, 2021
There is a vast amount of evidence that suggests that the geomagnetic tail is like a turbulent wake behind an obstacle. Large-scale vortices in the wake are able to generate turbulent transport that takes place both along the plasma sheet, in the X and Y

A Story of Developing the Idea of Plasma-Sheet Flow Braking

Frontiers in Astronomy and Space Sciences, 2022
This paper reports a story of developing the idea of Earthward ion flow braking in the near-Earth plasma sheet and its relationship with substorm onset processes.

Is the Solar Wind Electron Strahl a Seed Population for the Earth’s Electron Radiation Belt?

Frontiers in Astronomy and Space Sciences, 2022
1) Since the outer electron radiation belt is lost on occasion, the radiation belt needs seed electrons to rebuild. 2) The clear candidate for that seed population is energetic substorm-injected electrons in the dipolar magnetosphere.

Preservation and variation of ion-to-electron temperature ratio in the plasma sheet in geo-magnetotail

Earth and Planetary Physics, 2021
The ion-to-electron temperature ratio is a good indicator of the processes involved in solar wind plasma entering and being transported inside Earth’s plasma sheet.

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.

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.

Survey of deep tail plasma sheet crossings: Plasma sheet distributions resulting from reconnection [PDF]

Geophysical Research Letters, 2001
We illustrate the structure of the distant (X < −60 Re) plasma sheet and separatrix layers in terms of low energy ion distributions observed by Geotail. In a statistical survey, ion distributions are classified as single or multi‐component. Multi‐component populations are clearly observed in 68% of tailward flows.
