The Cluster Virtual Observatory for ULF Waves

Journal of Geophysical Research: Space Physics, 2023
AbstractSince its launch in 2000, the Cluster fleet visited a vast domain of the circum‐terrestrial environment, from the upstream solar wind and the distant tail, down to the plasmasphere, scanning in detail all magnetospheric regions during over two solar cycles.

Formation of a magnetic duct by the compressional component of ULF oscillation: a ray tracing study of whistler-mode wave propagation

Earth, Planets and Space
We investigate the propagation of whistler-mode waves in ultralow frequency (ULF) wave-derived magnetic ducts using ray tracing simulations in a two-dimensional dipole coordinate system on the meridian plane. The refractive index modulation caused by the

Ultra-Low Frequency Waves of Foreshock Origin Upstream and Inside of the Magnetospheres of Earth, Mercury, and Saturn Related to Solar Wind–Magnetosphere Coupling

Universe
This review examines ultra-low frequency (ULF) waves across different planetary environments, focusing on Earth, Mercury, and Saturn. Data from spacecraft missions (CHAMP, Swarm, and Oersted for Earth; MESSENGER for Mercury; and Cassini for Saturn ...

Solar cycle evolution of ULF wave power in solar wind and on ground

Journal of Space Weather and Space Climate, 2020
The solar cycle evolution of the ultra-low frequency (ULF) power was studied in solar wind and on ground. We aim finding out how the ULF power in interplanetary and on ground magnetic field evolves over the solar cycle 23 (SC23) and how well do they ...

Effects of ULF wave power on relativistic radiation belt electrons: 8-9 October 2012 geomagnetic storm [PDF]

, 2016
Electromagnetic ultralow-frequency (ULF) waves are known to play a substantial role in radial transport, acceleration, and loss of relativistic particles trapped in the Earth's outer radiation belt.

Chiral unitary meson-baryon dynamics in the presence of resonances: Elastic pion-nucleon scattering [PDF]

, 1999
We develop a novel approach to chiral meson-baryon dynamics incorporating unitarity constraints and explicit resonance fields. It is based on the most general structure of any pion-nucleon partial wave amplitude neglecting the unphysical cuts as derived ...

A comparison of EISCAT and HF Doppler observations of a ULF wave [PDF]

Annales Geophysicae, 1998
Since the middle of 1995, an HF Doppler sounder has been running almost continuously in northern Norway, with the receiver at Ramfjordmoen and the transmitter at Seljelvnes.

Ultralow-frequency modulation of whistler-mode wave growth [PDF]

, 2011
Measurements from ground-based magnetometers and riometers at auroral latitudes have demonstrated that energetic (~30-300keV) electron precipitation can be modulated in the presence of magnetic field oscillations at ultra-low frequencies.

Multisatellite studies of ULF waves

Advances in Space Research, 1988
Multisatellite studies of ULF waves are reviewed, with a special emphasis on compressional Pc 5 waves. The observations of the radial extent, azimuthal wave number and the field-aligned standing wave structure of the waves are described. When combined with plasma data, the waves appear to be consistent with drift-mirror waves originating from the ...

Magnetohydrodynamic modeling of three Van Allen Probes storms in 2012 and 2013 [PDF]

Annales Geophysicae, 2015
Coronal mass ejection (CME)-shock compression of the dayside magnetopause has been observed to cause both prompt enhancement of radiation belt electron flux due to inward radial transport of electrons conserving their first adiabatic invariant and ...
