On the validity of nonlinear Alfvén resonance in space plasmas [PDF]

, 2008
Aims. In the approximation of linear dissipative magnetohydrodynamics (MHD), it can be shown that driven MHD waves in magnetic plasmas with high Reynolds number exhibit a near resonant behaviour if the frequency of the wave becomes equal to the local ...

Excitation of kinetic Alfvén turbulence by MHD waves and energization of space plasmas [PDF]

Nonlinear Processes in Geophysics, 2004
There is abundant observational evidence that the energization of plasma particles in space is correlated with an enhanced activity of large-scale MHD waves.

Ray Tracing of MHD Rossby Waves in the Solar Tachocline: Meridional Propagation and Implications for the Solar Magnetic Activity

Frontiers in Astronomy and Space Sciences, 2022
Rossby waves have been recently recognised for their role in the large-scale spatio-temporal organisation of the solar magnetic activity. Here, we study the propagation of magnetohydrodynamic Rossby waves in a thin layer, representing the solar ...

Theoretical modeling of propagation of magneto-acoustic waves in magnetic regions below sunspots [PDF]

, 2008
We use 2D numerical simulations and eikonal approximation, to study properties of MHD waves traveling below the solar surface through the magnetic structure of sunspots. We consider a series of magnetostatic models of sunspots of different magnetic field

On the nature of kink MHD waves in magnetic flux tubes

, 2009
Magnetohydrodynamic (MHD) waves are often reported in the solar atmosphere and usually classified as slow, fast, or Alfv\'en. The possibility that these waves have mixed properties is often ignored.

Time damping of non-adiabatic magnetohydrodynamic waves in a partially ionized prominence plasma: Effect of helium

, 2009
Prominences are partially ionized, magnetized plasmas embedded in the solar corona. Damped oscillations and propagating waves are commonly observed. These oscillations have been interpreted in terms of magnetohydrodynamic (MHD) waves.

A three dimensional magnetohydrodynamic pulse in a transversely inhomogeneous medium [PDF]

, 2002
Interaction of impulsively generated MHD waves with a one-dimensional plasma inhomogeneity, transverse to the magnetic field, is considered in the three-dimensional regime.

On MHD waves, fire-hose and mirror instabilities in anisotropic plasmas [PDF]

Nonlinear Processes in Geophysics, 2007
Temperature or pressure anisotropies are characteristic of space plasmas, standard magnetohydrodynamic (MHD) model for describing large-scale plasma phenomena however usually assumes isotropic pressure. In this paper we examine the characteristics of MHD
