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

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.

The 600 keV electron injections in the Earth’s outer radiation belt: A statistical study
Earth and Planetary Physics, 2022 Relativistic electron injections are one of the mechanisms of relativistic (≥0.5 MeV) electron enhancements in the Earth’s outer radiation belt. In this study, we present a statistical observation of 600 keV electron injections in the outer radiation ...

Energetic Electron Flux Predictions in the Near‐Earth Plasma Sheet From Solar Wind Driving
Space Weather, 2022 Suprathermal electrons in the near‐Earth plasma sheet are important for inner magnetosphere considerations. They are the source population for outer radiation belt electrons and they pose risks to geosynchronous satellites through their contribution to ...

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.
