Plasma wave interactions with energetic ions near the magnetic equator
TLDR
In this article, it is suggested that these waves are interacting with energetic protons, alpha particles, and other heavy ions trapped near the magnetic equator, and the possible role these waves play in controlling the distribution of the energetic ions is considered.Abstract:
An intense band of electromagnetic noise is frequently observed near the magnetic equatorial plane at radial distance from about 2 to 5 Re. Recent wideband wave-form measurements with the IMP-6 and Hawkeye-1 satellites have shown that the equatorial noise consists of a complex superposition of many harmonically spaced lines. Several distinctly different frequency spacings are often evident in the same spectrum. The frequency spacing typically ranges from a few Hz to a few tens of Hz. It is suggested that these waves are interacting with energetic protons, alpha particles, and other heavy ions trapped near the magnetic equator. The possible role these waves play in controlling the distribution of the energetic ions is considered.read more

The terrestrial ring current: Origin, formation, and decay
TL;DR: The ring current is formed by the injection of ions originating in the solar wind and the terrestrial ionosphere and undergo an azimuthal drift as mentioned in this paper, resulting in a rapid intensification of the ring current and an O 1 dominance around storm maximum.

Electron acceleration in the Van Allen radiation belts by fast magnetosonic waves
Richard B. Horne,Richard M. Thorne,Sarah A. Glauert,Nigel P. Meredith,Dimitry Pokhotelov,Ondřej Santolík,Ondřej Santolík +6 more
TL;DR: In this article, fast magnetosonic waves, detected by Cluster 3, can accelerate electrons between ∼10 keV and a few MeV inside the outer radiation belt, which is required to explain electron flux increases in the outer Van Allen radiation belt during magnetic storms.

Slot region electron loss timescales due to plasmaspheric hiss and lightning‐generated whistlers
TL;DR: In this article, the relative importance of plasmaspheric hiss and lightning-generated whistlers in the slot region and beyond was assessed using the pitch angle and energy diffusion of Ions and Electrons (PADIE) code with global models of the spectral distributions of the wave power.

A systematic study of ULF Waves Above FH+ from GEOS 1 and 2 Measurements and Their Relationships with proton ring distributions
S. Perraut,Alain Roux,Patrick Robert,Roger Gendrin,Jean-André Sauvaud,Jean-Michel Bosqued,G. Kremser,A. Korth +7 more
TL;DR: In this article, a detailed analysis of the ULF noise observed on the GEOS magnetic antennas in the frequency range ∼0.2'12 Hz has revealed the properties of structured emissions occurring just above the proton gyrofrequency whose existence was reported by Russell et al. (1970) and Gurnett (1976).

OGO 3 observations of ELF noise in the magnetosphere: 2. The nature of the equatorial noise
TL;DR: In this article, an examination of the noise present between 1 and 1000 Hz at the magnetic equator with the OGO 3 search coil magnetometer has revealed a previously unobserved class of signals existing only in the outer plasmasphere.
