Evolutions of equatorial ring current ions during a magnetic storm
Earth and Planetary Physics, 2020 In this paper, we present evolutions of the phase space density (PSD) spectra of ring current (RC) ions based on observations made by Van Allen Probe B during a geomagnetic storm on 23–24 August 2016.

Another way of deriving the ring current decay time during disturbed periods
Annals of Geophysics, 1995 Coupling parameter, E, and the total energy dissipated by the magnetosphere, UT, are determined for six disturbed periods, following three known criteria for UT computation.

Quantifying adiabatic motion in the outer radiation belt and ring current with invariant matching
Frontiers in Astronomy and Space SciencesAdiabatic motion is a fundamental reversible process for geomagnetically trapped particle populations, including particles comprising the ring current and radiation belts.

Persistent current in isolated mesoscopic rings
Physical Review B, 1994 Persistant current in isolated mesoscopic rings is studied using the continium and tight-binding models of independent electrons. The calculation is performed with disorder and also at finite temperature. In the absence of disorder and at zero temperature agreement is obtained with earlier results by D. Loss et.

Pitch Angle Structures of Ring Current Ions Induced by Evolving Poloidal Ultra‐Low Frequency Waves
Geophysical Research Letters, 2020 Ultra‐low frequency (ULF) waves can effectively accelerate ring current ions through drift‐bounce resonance. Conventional theories have been developed to understand this resonance since the dawn of the space age, which usually assume ULF waves are quasi ...

Charge-Exchange Byproduct Cold Protons in the Earth’s Magnetosphere
Frontiers in Astronomy and Space Sciences, 2022 Owing to the spatial overlap of the ion plasma sheet (ring current) with the Earth’s neutral-hydrogen geocorona, there is a significant rate of occurrence of charge-exchange collisions in the dipolar portion of the Earth’s magnetosphere.

The effect of non-storm time substorms on the ring current dynamics
Earth and Planetary Physics, 2021 During geomagnetically active times such as geomagnetic storms, large amounts of energy can be released into the Earth’s magnetosphere and change the ring current intensity.
