The role of nonlocal heat conduction in solar flares.
Abstract
The temperature scale height in the solar atmosphere, particularly in the transition region, may be comparable to or smaller than the collisional mean free paths of a substantial fraction of the electron population. The authors have modelled a flaring solar atmosphere with classical heat transport and with a nonlocal formulation of thermal transport which is valid for both shallow and steep temperature gradients. They conclude that nonlocal thermal transport can strongly affect the physical characteristics of the transition region and chromosphere during flares, with both flux limiting and delocalization playing important roles.
