Abstract
SynopsisThe Opacity Project is a highly successful venture in which energy levels, oscillator strengths, and photoionization cross sections were calculated for astrophysically important elements up to iron. However, metals heavier than iron are being discovered in stellar atmospheres. The photoionization cross sections for elements and ions not covered by the Opacity Project are usually approximated with hydrogenic formulae. We present a series of valence and inner-shell distorted wave photoioniza-tion cross section calculations for use in model atmosphere calculations covering Ni - Ni10+. We discuss current progress, and future work.
Highlights
The cross sections were calculated using the distorted wave code AUTOSTRUCTURE [3] We treat PI from different complexes separately, splitting the calculation into K-shell, L-shell, and M-shell respectively
