Alfven wave elgenmode and Alfven resonance.
Kakuyūgō kenkyū, 1985 The main purpose of this article is to introduce as simply as possible the current topics concerned with the Alfven waves ; new MHD surface waves, other eigenmodes, and the Alfven resonance. These play an important role for heating plasma by applying an rf field of ion cyclotron range of frequency to a plasma column.

Nonlinear Gyrokinetic Simulation of the Magnetosphere‐Ionosphere Feedback Coupling
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract A nonlinear gyrokinetic simulation is applied to the magnetosphere‐ionosphere (M‐I) coupling system to investigate spontaneous growth of auroral structures and electron acceleration self‐consistently. Perturbations of electron density, potential and field‐aligned current in the auroral ionosphere develop through the feedback instability ...

Alfvén waves in the magnetosphere generated by shock wave/plasmapause interaction
Solar-Terrestrial Physics, 2019 We study Alfvén waves generated in the magnetosphere during the passage of an interplanetary shock wave. After shock wave passage, the oscillations with typical Alfvén wave dispersion have been detected in spacecraft observations inside the magnetosphere.

STABILITY OF ALFVEN WINGS IN HMHD
Anales (Asociación Física Argentina), 2021 A conducting source moving uniformly through a magnetized plasma generates, among a variety of perturbations,Alfvén waves. Alfvén waves can build up structures in the plasma called Alfvén wings.

Fluid Models for Kinetic Effects on Coherent Nonlinear Alfven Waves. II. Numerical Solutions [PDF]
, 1996 The influence of various kinetic effects (e.g. Landau damping, diffusive and collisional dissipation, and finite Larmor radius terms) on the nonlinear evolution of finite amplitude Alfvenic wave trains in a finite-beta environment is systematically ...

Dataset of Quiet Space Weather Periods for Ionospheric Studies
Earth and Space Science, Volume 13, Issue 4, April 2026.Abstract The ionosphere is a dynamic environment regularly affected from above and from below. This study identifies periods within the years 2000–2023 when the impact from above, driven by space weather, was minimal. The quiet space weather periods have wide usage for two types of ionospheric studies. At first, studies of isolated space weather events

LARGE AMPLITUDE ALFVÉN WAVES IN MAGNETOHYDRYNAMICS CONSIDERING INERTIAL TERMS IN THE OHM’S LAW
Anales (Asociación Física Argentina)Incompressible Alfvén waves have been detected in a variety of space and astrophysical plasmas. Some of these plasmas can be studied within the framework of magnetohydrodynamics with extended conditions.

Alfvén wave evolution into magnetic filaments in 3-D space plasma
Earth, Planets and Space, 2020 Nonlinearities in space and astrophysical plasmas generate a set of magnetic filaments or bundles that have an incompressible sense of fluctuations and propagate highly obliquely to the mean magnetic field.

The Effect of the Parametric Decay Instability on the Morphology of Coronal Type III Radio Bursts
The Astrophysical Journal Letters, 2023 The nonlinear evolution of Alfvén waves in the solar corona leads to the generation of Alfvénic turbulence. This description of the Alfvén waves involves parametric instabilities where the parent wave decays into slow mode waves giving rise to density ...
