Saturn's ULF wave foreshock boundary: Cassini observations [PDF]

Planetary and Space Science, 2013
Even though the solar wind is highly supersonic, intense ultra-low frequency (ULF) wave activity has been detected in regions just upstream of the bow shocks of magnetized planets. This feature was first observed ahead of the Earth's bow shock, and the corresponding region was called the ULF wave foreshock, which is embedded within the planet's ...

Modulation of Whistler-mode Waves in the Solar Wind in the Vicinity of Earth’s Moon

The Astrophysical Journal
Ultra-low-frequency (ULF) waves are known to modulate high-frequency whistler-mode waves within the Earth’s magnetosphere. Periodic bursts of whistler-mode waves are excited in association with ULF perturbations of plasma density and magnetic field.

Statistical analysis of ground based magnetic field measurements with the field line resonance detector [PDF]

Annales Geophysicae, 2008
In this paper we introduce the field line resonance detector (FLRD), a wave telescope technique which has been specially adapted to estimate the spectral energy density of field line resonance (FLR) phase structures in a superposed wave field.

A correlative investigation of the propagation of ULF wave power through the dayside magnetosphere [PDF]

Three different ULF wave phenomena (azimuthally polarized Pc 3 pulsations, radially polarized Pc 4 pulsations, and solitary Pc 5 pulsations related to solar wind pressure pulses) were studied. The main problems covered are: (1) how do magnetospheric Pc 3-

High spatial and temporal resolution observations of an impulse-driven field line resonance in radar backscatter artificially generated with the Tromsø heater [PDF]

Annales Geophysicae, 1997
The CUTLASS Finland HF radar has been operated in conjunction with the EISCAT Tromsø RF ionospheric heater facility to examine a ULF wave characteristic of the development of a field line resonance (FLR) driven by a cavity mode caused by a ...

Control of ULF Wave Accessibility to the Inner Magnetosphere by the Convection of Plasma Density [PDF]

, 2018
During periods of storm activity and enhanced convection, the plasma density in the afternoon sector of the magnetosphere is highly dynamic due to the development of plasmaspheric drainage plume (PDP) structure.

The role of localised compressional Ultra-Low Frequency waves in energetic electron precipitation [PDF]

, 2018
Typically, Ultra-Low Frequency (ULF) waves have historically been invoked for radial diffusive transport leading to acceleration and loss of outer radiation belt electrons.

Relativistic electron flux growth during storm and non-storm periods as observed by ARASE and GOES satellites

Earth, Planets and Space, 2023
Variations of relativistic electron fluxes (E ≥ 1 MeV) and wave activity in the Earth magnetosphere are studied to determine the contribution of different acceleration mechanisms of the outer radiation belt electrons: ULF mechanism, VLF mechanism, and ...

Rapid acceleration of electrons in the magnetosphere by fast-mode MHD waves

, 2000
During major megnetic storms, enhanced flux of relativistic electrons in the inner magnetosphere have been observed to correleated with ULF waves. The enhancements can take place over a period of several hours.
