Coronal heating: Energy release associated with chromospheric magnetic reconnection

We examine a one-dimensional circularly symmetric supergranulation reconnec tion model with typical quiet-Sun values. In this model, the assumed source rate of elements determines heating, because all emerged elements eventual ly annihilate; the assumed collision cross section determines mean field-th e more efficient the interaction, the fewer elements exist at any time; and the effective element diffusivity determines the ratio of held strengths i n the network and cell interior. Power-law indices for the variation of the heating flux with the mean magnetic field were computed in order to allow comparisons to observations. The indices are found to be in the range 1.9-2 .0, and the only parameter that was found to have much effect on them was t he effective element diffusivity, where the index declines roughly logarith mically with decreasing diffusivity. Even this effect is fairly shallow, ho wever; a tenfold reduction in diffusivity only lowers the power-law index f rom 1.9 to 1.7.
