Time-Dependent Ionization in Solar Eruptions
Abstract
We propose to supply time-dependent ionization modules that can be with magnetohydrodynamics (MHD) simulations of solar eruptions. They can be used to compute the ionization states of several elements for comparison with the ionization states measured in space and for computation of the intensities of EUV emission lines observable from Earth-orbiting spacecraft. The key observational signatures for the state of the plasma in flux ropes ejected during solar eruptions are the ionization state at 1 AU and the UV and EUV intensities observed close to the Sun. The plasma ionization state is far from equilibrium, so the time-dependent ionization state must be computed in order to make predictions based on MHD models.
