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.

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.

Constraining Low-Frequency Alfvenic Turbulence in the Solar Wind Using Density Fluctuation Measurements

, 2009
One proposed mechanism for heating the solar wind, from close to the sun to beyond 10 AU, invokes low-frequency, oblique, Alfven-wave turbulence. Because small-scale oblique Alfven waves (kinetic Alfven waves) are compressive, the measured density ...

Chromospheric Damping of Alfven Waves

The Astrophysical Journal, 2001
We analytically study the damping of Alfven mode oscillations in the chromosphere and in coronal loops. In the partially ionized chromosphere the dominant damping process of Alfven waves is due to collisions between ions and neutrals. We calculate the damping time for Alfven waves of a given frequency, propagating through model chromospheres of various

Enabling High‐Fidelity Wave‐Particle Interaction Studies: A Novel Filtering for Isolating Whistlers From Spacecraft Noise

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Resolving the mixture of natural plasma waves and persistent spacecraft interference is a fundamental challenge in space physics, as it obstructs the analysis of wave‐particle interactions and energy transport processes. Traditional signal decomposition methods often fail to adequately separate these components due to their time‐varying ...

Natural Generation of Alfvén Waves from Three-dimensional Bursty Interchange Magnetic Reconnection in the Solar Corona

The Astrophysical Journal Letters
Alfvén 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.

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 ...

Comparative Analysis of the Primary Drivers of Plasma Sheet Electron Precipitation

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Plasma sheet electron precipitation into Earth's atmosphere plays a key role in magnetosphere–ionosphere coupling at auroral latitudes. Such precipitation can be driven by four primary mechanisms that scatter equatorial electrons into the loss cone: resonant interactions with whistler‐mode waves, electron cyclotron harmonics (ECH), broadband ...

Force-free Wave Interaction in Magnetar Magnetospheres: Computational Modeling in Axisymmetry

The Astrophysical Journal
Crustal 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
