Coronal Heating by MHD Waves [PDF]

Space Science Reviews, 2020
The heating of the solar chromosphere and corona to the observed high temperatures, imply the presence of ongoing heating that balances the strong radiative and thermal conduction losses expected in the solar atmosphere. It has been theorized for decades

Introduction to MHD Instabilities

Fusion Science and Technology, 1998
In this paper we will discuss the theoretical framework of ideal MHD stability. We first show that the Alfven wave is of central importance for the understanding of macroscopic plasma dynamics and, hence, of MHD stability. Then we introduce the elements of spectral theory needed for our study, and next we apply these methods to inhomogeneous plasmas in

Weak Solutions of Ideal MHD Which Do Not Conserve Magnetic Helicity

Annals of PDE, 2019
We construct weak solutions to the ideal magneto-hydrodynamic (MHD) equations which have finite total energy, and whose magnetic helicity is not a constant function of time.

Entropy Stable Finite Volume Scheme for Ideal Compressible MHD on 2-D Cartesian Meshes

SIAM Journal on Numerical Analysis, 2016
We present a finite volume scheme for ideal compressible magnetohydrodynamic (MHD) equations on two-dimensional Cartesian meshes. The semidiscrete scheme is constructed to be entropy stable by using the symmetrized version of the equations as introduced ...

Theory of MHD waves [PDF]

Plasma Physics and Controlled Fusion, 1986
Reviews recent developments in the theory of MHD waves in connection with radio-frequency heating in the Alfven wave and ion cyclotron ranges of frequencies (AWRF, ICRF). The account focuses on the discussion of full wave solutions and the oscillation spectra in bounded, generally inhomogeneous, plasmas. Original results are presented concerning forced
