The Opacity Project (OP) and Iron Project (IP) are pioneering international collaborations which have been computing, for more than 25 years, massive atomic data sets for astrophysical applications. We review the data activities that have been carried out, namely curation, analysis and preservation, and the development of databases and computer tools for data dissemination and end-user processing. New opportunities within the current data-intensive boom referred to as e-science are described…

On the importance of inner-shell transitions for opacity calculations
For high temperatures and densities, stellar opacities obtained from the Opacity Project (OP) were smaller than those obtained from the OPAL project. Iglesias and Rogers (1995 Astrophys. J. 443 469)…
The XSTAR Atomic Database
TLDR
The XSTAR atomic database that contains a large quantity of atomic rates for use in spectral modeling of astrophysical plasmas is reported on, including incorporation of photoionization cross sections from the Opacity Project for all levels of every ion, and state-specific recombination rates.
Updated opacities from the Opacity Project
Using the code autostructure, extensive calculations of inner-shell atomic data have been made for the chemical elements He, C, N, O, Ne, Na, Mg, Al, Si, S, Ar, Ca, Cr, Mn, Fe and Ni. The results are…
