WorkOp-IV summary: lessons from iron opacities

TL;DR: The fourth international LTE opacity workshop and code comparison study, WorkOp-IV, was held in Madrid in 1997 as mentioned in this paper, with a focus on iron opacities, and the astrophysically important photon absorption region between 50 and 80 eV was emphasized for a sequence of iron plasmas at densities and temperatures that produce nearly the same average ionization stage (Z ∗ ∼8.6).

Abstract: The fourth international LTE opacity workshop and code comparison study, WorkOp-IV, was held in Madrid in 1997. Results of this workshop are summarized with a focus on iron opacities. In particular, the astrophysically important photon absorption region between 50 and 80 eV is emphasized for a sequence of iron plasmas at densities and temperatures that produce nearly the same average ionization stage (Z ∗ ∼8.6) . Experimental data that addressed this spectral region is also reviewed.
