Nonlinear interactions between three inertial Alfvén waves
, 2007 The resonant coupling between Alfvén waves is reconsidered. New results are found for cold agnetoplasmas where temperature effects are negligible.

The Astrophysical Journal LettersAlfvén waves play a significant role in solar coronal heating, solar wind acceleration, and Alfvénic turbulence formation. As a fundamental process, magnetic reconnection has long been credited as a crucial source of Alfvén waves.

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 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.

Reconnection Onset in Overstretched Thin Current Sheets: 3‐D Kinetic Picture
Journal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.Abstract Evolution of the magnetotail equilibrium, whose current density iso‐contours are stretched beyond the magnetic field lines due to small ion anisotropy and agyrotropic effects on the scales of the thermal ion gyroradius (the so‐called overstretched thin current sheet) is considered using 3‐D explicit particle‐in‐cell simulations.

Discrete Alfvén Waves in Solar Prominences: Preliminary Studies
Brazilian Journal of Geophysics, 1990 It is shown that the Discrete Alfvén wave can explain the natural oscillations of solar prominences by considering the existence of a current flow.

Auroral vortex street formed by the magnetosphere–ionosphere coupling instability [PDF]
Annales Geophysicae, 2015 By performing three-dimensional magnetohydrodynamic simulations including Alfvén eigenmode perturbations most unstable to the ionospheric feedback effects, we examined the auroral vortex street that often appears just before substorm onset.

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.

Journal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.Abstract Measuring field‐aligned currents (FACs) using magnetic field observations provides a powerful means to probe the multi‐scale interactions between the magnetosphere, ionosphere and thermosphere. In this study, we benchmark the curlometer technique using Swarm spacecraft observations and simulations of the coupled magnetosphere‐ionosphere system.

Force-free Wave Interaction in Magnetar Magnetospheres: Computational Modeling in Axisymmetry
The Astrophysical JournalCrustal quakes of highly magnetized neutron stars can disrupt their magnetospheres, triggering energetic phenomena like X-ray and fast radio bursts. Understanding plasma wave dynamics in these extreme environments is vital for predicting energy transport
