Abstract

We develop mathematical models describing plasma heating in the corona by heat fluxes from a super-hot (T \hbox{$ \stackrel{>}{_\sim}}T~>108 108 K) reconnecting current layer in solar flares. The effect of collisional relaxation is shown to be important in these conditions. Taking this effect into account, we have computed the electron-temperature distributions in the vicinity of the current layer, differential and integral emission measures of the heated plasma, the intensities of spectral lines Fe XXVI (1.78 and 1.51 Å) and Ni XXVII (1.59 Å). The theoretical results are compared with observations.
