The interactions between ULF waves and cold charged particles in the Earth's magnetosphere

地球与行星物理论评, 2022
In the solar wind-magnetosphere coupling processes, many kinds of plasma waves can be excited in the Earth's magnetosphere including ULF waves, hiss waves, chorus waves, etc. Among these waves, ULF waves are featured by the lowest wave frequency (1 mHz～1

Quantifying hiss-driven energetic electron precipitation: A detailed conjunction event analysis [PDF]

, 2014
We analyze a conjunction event between the Van Allen Probes and the low-altitude Polar Orbiting Environmental Satellite (POES) to quantify hiss-driven energetic electron precipitation.

Variation in Plasmaspheric Hiss Wave Power With Plasma Density

Geophysical Research Letters, 2018
AbstractPlasmaspheric hiss waves are commonly observed in the inner magnetosphere. These waves efficiently scatter electrons, facilitating their precipitation into the atmosphere. Predictive inner magnetosphere simulations often model hiss waves using parameterized empirical maps of observed hiss power. These maps nearly always include parameterization

The Relationship of Exohiss Waves With Plasmaspheric Hiss Distribution and Solar Wind Parameters

Journal of Geophysical Research: Space Physics, 2023
AbstractExohiss waves below 0.1 electron cyclotron frequency (fce) are structureless whistler‐mode emissions typically observed in the plasmatrough. Plasmaspheric hiss may possibly propagate from the plasmasphere into the plasmatrough and evolve into exohiss waves.

Low-altitude measurements of 2–6 MeV electron trapping lifetimes at 1.5 ≤ L ≤ 2.5 [PDF]

, 2007
During the Halloween Storm period (October–November 2003), a new Van Allen belt electron population was powerfully accelerated. The inner belt of electrons formed in this process decayed over a period of days to years. We have examined quantitatively the

Realistic Dispersion of Plasmaspheric Hiss in the Inner Magnetosphere and Its Effect on Wave-induced Electron Scattering Rates [PDF]

The Astrophysical Journal, 2021
Abstract The cold plasma approximation is a common treatment to study wave–particle interactions between plasmaspheric hiss and magnetospheric electrons, which, however, can become a challenge during periods of disturbed geomagnetic activity.

Modeling the properties of plasmaspheric hiss: 1. Dependence on chorus wave emission [PDF]

Journal of Geophysical Research: Space Physics, 2012
There is increasing evidence that plasmaspheric hiss is formed by the evolution of a portion of chorus waves that are excited in the plasmatrough and propagate into the plasmasphere. Comparison between the statistical spatial distributions of these two emissions in the morning sector during active times from THEMIS over ∼3 years shows that the two ...

Temporal variability of quasi-linear pitch-angle diffusion

Frontiers in Astronomy and Space Sciences, 2022
Kinetic wave-particle interactions in Earth’s outer radiation belt energize and scatter high-energy electrons, playing an important role in the dynamic variation of the extent and intensity of the outer belt.

Plasmatrough exohiss waves observed by Van Allen Probes: Evidence for leakage from plasmasphere and resonant scattering of radiation belt electrons [PDF]

, 2015
Exohiss waves are whistler mode hiss observed in the plasmatrough region. We present a case study of exohiss waves and the corresponding background plasma distributions observed by the Van Allen Probes in the dayside low-latitude region.

Generation of unusually low frequency plasmaspheric hiss [PDF]

, 2014
It has been reported from Van Allen Probe observations that plasmaspheric hiss intensification in the outer plasmasphere, associated with a substorm injection on 30 September 2012, occurred with a peak frequency near 100 Hz, well below the typical ...
