Mixed Properties of MHD Waves in Non-uniform Plasmas

Frontiers in Astronomy and Space Sciences, 2019
This paper investigates the mixed properties of MHD waves in a non-uniform plasma. It starts with a short revision of MHD waves in a uniform plasma of infinite extent. In that case the MHD waves do not have mixed properties.

On the nature of kink MHD waves in magnetic flux tubes

Astronomy and Astrophysics, 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.

Propagating MHD Waves in Coronal Holes [PDF]

Space Science Reviews, 2010
Coronal holes are the coolest and darkest regions of the solar atmosphere, as observed both on the solar disk and above the solar limb. Coronal holes are associated with rapidly expanding open magnetic fields and the acceleration of the high-speed solar wind.

Collisional and viscous damping of MHD waves in partially ionized plasmas of the solar atmosphere [PDF]

Astronomy and Astrophysics, 2004
Magnetohydrodynamic (MHD) waves are widely considered as a possible source of heating for various parts of the outer solar atmosphere. Among the main energy dissipation mechanisms which convert the energy of damped MHD waves into thermal energy are ...

Coronal Waves and Oscillations

Living Reviews in Solar Physics, 2005
Wave and oscillatory activity of the solar corona is confidently observed with modern imaging and spectral instruments in the visible light, EUV, X-ray and radio bands, and interpreted in terms of magnetohydrodynamic (MHD) wave theory.

Optical Coherence Tomography for Detection of Dental Cracks and Vertical Root Fracture: A Scoping Review. [PDF]

Clin Exp Dent Res
ABSTRACT Objectives Vertical root fractures (VRFs) pose significant clinical challenges and may result in tooth loss. Current diagnostic methods, including conventional radiography and CBCT, are challenging to detect VRFs, especially in the early stages. Optical coherence tomography (OCT) has recently been introduced as a non‐invasive imaging technique

Nonlinear Fast Magnetosonic Waves in Solar Prominence Pillars

The Astrophysical Journal, 2023
We investigate the properties of nonlinear fast magnetosonic (NFM) waves in a solar prominence, motivated by recent high-resolution and high-cadence Hinode/Solar Optical Telescope (SOT) observations of small-scale oscillations in a prominence pillar.

Peculiarities of ULF wave characteristics in a multicomponent ionospheric plasma

Solar-Terrestrial Physics, 2022
We have examined the properties of low-frequency electromagnetic waves in multicomponent ionospheric plasma in the 1–30 Hz band, using the magnetoionic theory.

Linear and nonlinear resonant interaction of sound waves in dissipative layers [PDF]

, 2000
The theory of resonant nonlinear magnetohydrodynamic (MHD) waves in dissipative steady plasmas developed by Ballai and Erdélyi is used to study the effect of steady flows on nonlinear resonant heating of MHD waves in (a) linear, (b) weakly and (c ...

Simulations of Incompressible MHD Turbulence [PDF]

, 2000
We simulate incompressible MHD turbulence in the presence of a strong background magnetic field. Our major conclusions are: 1) MHD turbulence is most conveniently described in terms of counter propagating shear Alfven and slow waves.
