Nonlinear wave heating of solar coronal loops.

Astronomy and Astrophysics, 1997
The heating of magnetically closed structures (loops) in the solar corona by the resonant absorption of incident waves is studied by means of numerical simulations in the framework of nonlinear resistive magnetohydrodynamics (MHD). It is shown that the dynamics in the resonant layer is indeed very nonlinear for typical coronal parameters. The effect of

Solar coronal heating by high-frequency dispersive Alfvén waves

Solar Physics, 1999
It is shown that high-frequency dispersive kinetic Alfven waves can cause significant electron heating in the solar corona. The heating is produced by collisionless electron Landau dissipation of the parallel electron current associated with high-frequency dispersive kinetic Alfven waves, which have a parallel electric field.

Observational Research on Solar Coronal Waves.

1976
Abstract : An observational search has been made for intensity fluctuations associated with the wave motions that are thought to heat the corona. Brightness changes in the coronal green line (Fe XIV lambda 5303) and the coronal continuum were measured with the University of Hawaii's polarimeter at Mt. Haleakala.

Impulsively Generated Wave Trains in a Solar Coronal Loop

IEEE Transactions on Plasma Science, 2010
Impulsively generated fast magnetoacoustic wave trains in a solar coronal loop are numerically studied. The problem is considered as 2-D in space, and for the description, the full set of magnetohydrodynamic (MHD) equations is used. The numerical solution of the MHD equations is performed by means of the Lax-Wendroff algorithm on a uniformly structured

Solar Coronal Heating via Alfvén Wave Turbulence

AIP Conference Proceedings, 2010
A short review is given about the self‐consistent MHD model of solar coronal heating recently proposed by Bigot et al. (2008) in which the dynamical effect of the background magnetic field along a coronal structure is taken into account through exact results from Alfven wave turbulence.

Reflection of Alfvén Waves and Heating in Solar Coronal Holes

1991
Using a simple model coronal hole, we estimate the short-period period limit for the reflection of Alfven waves in solar coronal holes. Waves with periods longer than this limit are strongly reflected and blocked from escaping into the solar wind; waves with periods appreciably shorter than this limit suffer little reflection and freely escape into the
