Chromospheric heating during a flare
Abstract
Flares are now believed to be complex processes initiated in the corona and largely influencing the lower atmospheric layers. The energy is transported from the corona down to the chromosphere and even photosphere in various modes and this leads to significant heating of the chromospheric plasma. We will review individual processes among which the most important is the particle-beam propagation and dissipation, but others as conduction, XUV heating, wave heating etc. are also to be considered. We will summarize recent results of the radiation-hydrodynamical simulations of the chromospheric heating during flares and the progress in our understanding of the basic heating mechanisms and flows. We will also point to new space and ground observations which provide the critical constraints to modeling.
