The Excitation Equilibrium in the Solar Corona and Non-Maxwellian Electron Distributions

Abstract

AbstractWe demonstrate the influence of an electron non-Maxwellian distribution function on the collisional excitation coefficient and, as an example, on the excitation equilibrium of Fe XIV in the solar corona. The results can be used for specific applications in the solar corona, especially in the active corona, where deviations from Maxwellian distribution can be significant.
