Alfven solitons in the solar wind [PDF]

, 1983
A nonlinear Alfven soliton solution of the MHD equations is presented. This solution represents the final state of modulationally unstable Alfven waves.

Parametric interactions between Alfven waves and sonic waves [PDF]

IEEE Transactions on Antennas and Propagation, 1973
Parametric interactions between a sonic pump wave and a weak Alfven wave are studied. It is shown that if the Alfven-wave velocity V_{A} is small relative to the sonic-wave velocity V_{s} there is a time-growing instability leading to the increase of the Alfven wave at the expense of the sonic wave.

Poloidal Field Line Resonances Driven by a Fast Wave

Geophysical Research Letters
We 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 ...

Exploring the Impact of Self-Excited Alfvén Waves on Transonic Winds: Applications in Galactic Outflows

Universe
The impact of cosmic rays is crucial to understand the energetic plasma outflows coming out from the Galactic centers against the strong gravitational potential well.

On resistive dissipation of Alfvén waves in an isothermal atmosphere

International Journal of Mathematics and Mathematical Sciences, 1996
In this paper we will examine the reflection and dissipation of Alfvén waves, resulting from a uniform vertical magnetic field, in an inviscid, resistive and isothermal atmosphere.

The Energy Content of Alfvén Waves in the Stratified Solar Atmosphere

The Astrophysical Journal
Alfvén waves propagating in a vertically stratified plasma, such as those traveling from the solar photosphere to the corona, are partially reflected due to the gradient in the Alfvén speed.

Review article: MHD wave propagation near coronal null points of magnetic fields

, 2012
We present a comprehensive review of MHD wave behaviour in the neighbourhood of coronal null points: locations where the magnetic field, and hence the local Alfven speed, is zero. The behaviour of all three MHD wave modes, i.e.

Heating of the Solar Chromosphere and Corona by Alfven Wave Turbulence

, 2011
A three-dimensional MHD model for the propagation and dissipation of Alfven waves in a coronal loop is developed. The model includes the lower atmospheres at the two ends of the loop.

On the Correlation between Alfvén Waves and Auroral Radio Emissions in the Jovian System

The Astrophysical Journal
Jupiter’s powerful aurorae reflect intense energy dissipation in the magnetosphere–ionosphere system. Recent studies reveal that solar wind compression systematically enhances auroral emission, while the mechanism is not yet fully understood.
