On the problem of heat transport in the solar atmosphere // In Proceedings of Symposium 3 of JENAM 2011. — Vol. 30 of Astrophysics and Space Science Proceedings. — 11 WEST 42ND STREET, NEW YORK, USA, NY,10036: 11 WEST 42ND STREET, NEW YORK, USA, NY,10036, 2012. — P. 39–46. In the context of the problem of energy transport in the solar atmosphere, we present new results on physical properties of a transition region between the hot and cold plasma in quiet regions and in flares. In quiet regions, the transition region between the corona and chromosphere is shown to be a very thin layer, in which however the classical collisional approach is valid very well. A stability of the transition region is investigated. It is shown to be stable, more exactly, it is a stable consequence of the thermal instability in the condensation mode regime. We have developed also mathematical models for describing plasma heating in the corona and chromosphere by heat fluxes from a super-hot reconnecting current layer. It is shown that applicability conditions of classical heat conduction are not valid in the flare transition region and at the higher temperatures. Models, accounting the effect of collisional relaxation better describe heat transport in flares than Fourier's law. A possibility of comparing theoretical and observational data is discussed.
