On the modeling of visible sunspot layers

Abstract

One option for a stationary model of the asymmetric sunspot previously presented by the authors is considered. It is shown that the presence of sub-Alfvénic Evershed flows in the sunspot penumbra has almost no effect on the temperature distribution in the dense photospheric layers of the sunspot but significantly lowers the temperature of the chromosphere and the lower corona above the sunspot penumbra up to heights of 5–6 Mm.
