Chianti: Inclusion of Ionization and Recombination Rates
Abstract
The spectrum produced by an astrophysical plasma is directly dependent on the ionization state of the plasma. In order to understand the ionization balance it is necessary to know the ionization and recombination rates of the various ions whether the plasma is in a steady-state ionization state or a transient ionization state.
New and improved measurements and calculations of ionization and recombination rate continue to become available. We have collected the various measurements and calculations for inclusion into the CHIANTI database. We have developed a scaling law for the ionization rates similar to that of Burgess and Tully (1992) for electron excitation rates. We will discuss our progress the adjustments needed for the new rates and the need for more measurements and calculations.- Publication:
