Swing wave-wave interaction:Coupling between fast magnetosonic and Alfven waves
, 2002 We suggest a mechanism of energy transformation from fast magnetosonic waves propagating across a magnetic field to Alfven waves propagating along the field. The mechanism is based on swing wave-wave interaction [T. V. Zaqarashvili, Astrophys. J.

Plasma Frequency Waves in Earth's Electron Foreshock
Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.Abstract At Earth's quasi‐perpendicular bow shock, electrons are reflected and accelerated to high velocities, forming beams. These beams excite Langmuir and beam‐mode waves in the electron foreshock region. The waves can then be converted to radio waves via linear or nonlinear processes.

Coronal heating by Alfven waves
, 2019 Coronal heating by Alfven waves is reexamined considering the effect of the the granular structure of the sun's surface. From the observation that the Alfven waves in the sun's atmosphere are originally generated by the surface granular motion,

Microscale Alfven waves in the solar wind at 1 AU [PDF]
, 1974 Analysis of IMP 1 (Explorer 43) plasma and magnetic field fluctuations on a scale of one hour revealed that linearly and circularly polarized Alfven waves are rarely present in the solar wind at 1 AU.

Detection of waves in the solar corona : kink or Alfven?
, 2008 Recently, the omnipresence of waves has been discovered in the corona using the CoMP instrument. We demonstrate that the observational findings can be explained in terms of guided kink magnetoacoustic modes.

Coupling of the solar wind, magnetosphere and ionosphere by MHD waves [PDF]
, 2012 The solar wind, magnetosphere and ionosphere are coupled by magnetohydrodynamic waves, and this gives rise to new and often unexpected behaviours that cannot be produced by a single, isolated part of the system.

Poloidal Field Line Resonances Driven by a Fast Wave
Geophysical Research LettersWe present numerical simulations of the excitation of resonant poloidal Alfvén waves. The resulting Alfvén waves could be loosely described as “high‐m” (m is the azimuthal wave number) in as much as the azimuthal scale of the wave is much less than the ...

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.Abstract In this study, we propose a new mechanism to explain the observed particle flux at discrete energies in the flux tubes connecting to the wakes of the Galilean moons, first reported by Sarkango et al. (2024, https://doi.org/10.1029/2023gl107431) and referred to as “banded flux.” We demonstrate the proposed mechanism using test particle ...

Drift Echoes at Geostationary Orbit: An Eight‐Year Climatology From GOES‐16
Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.Abstract Drift echoes are energy‐dispersed recurrences in energetic particle flux that appear when a localized injection or compression organizes trapped ions and electrons according to their azimuthal drift. Although established as tracers of radiation‐belt dynamics, drift echoes have rarely been surveyed statistically at geostationary orbit. We apply
