Description
In this paper, we show a “proof of concept” of the heating
mechanism of the solar chromosphere due to wave dissipation caused by
the effects of partial ionization. Numerical modeling of non-linear wave
propagation in a magnetic flux tube, embedded in the solar atmosphere,
is performed by solving a system of single-fluid quasi-MHD equations,
which take into account the ambipolar term from the generalized
Ohm’s law. It is shown that perturbations caused by magnetic waves
can be effectively dissipated due to ambipolar diffusion. The energy
input by this mechanism is continuous and shown to be more efficient
than dissipation of static currents, ultimately leading to chromospheric
temperature increase in magnetic structures.
