Non-LTE radiative hydrodynamic interactions in the solar chromosphere.
Abstract
Strong, optically thick lines from iron and from ionized calcium and magnesium dominate the radiative losses of the solar chromosphere. This radiative loss cannot be approximated in the optically thin limit or by a grey approximation. In order to properly calculate the effects of waves in the chromosphere it is necessary to solve simultaneously the equations of hydrodynamics, radiative transfer and statistical equilibrium. Efficient methods in radiative transfer are here being combined with a treatment of the dynamical equations capable of resolving shocks. The authors present the first results showing that radiative hydrodynamic interactions may have a significant effect on the heating by acoustic waves.
