Abstract Keywords
The mathematical model of Alfven wave absorption makes
it possible, in particular, to explain the anomalous heating
of the solar corona by Alfven waves generated in the lower,
much colder layers of the sun. According to calculations,
Alfven wave absorption occurs over distances of the skin
order, on which classical magnetohydrodynamics (MHD)
equations are obviously inapplicable. Therefore, the re-
search is based on equations of the two-fluid MHD with a
full account of the electron inertia. The study revealed
a number of important regularities, in particular, the depth
finitness of the layer heating, where Alfven waves penetrate
into plasma. In our research we evaluated the penetration
depth and established the parameters of Alfven waves
absorbed, and their convergence to the quasi-stationary
mode
