The workshop “Uncertainties in atomic data and how they propagate in chemical abundances” was held at the Instituto de Astrofísica de Canarias, Tenerife, Spain, during 25-27 October 2010. The aim of the workshop was to bring together atomic data producers and users, the latter mainly in the field of nebular astrophysics. It was attended by an international group of around 20 researchers (see participants list) with an interesting scientific programme (pdf presentations included) that emphasized problems and successes in accurate atomic data calculations, assessments and benchmarking; precision abundances in nebular astrophysics and AGNs; the role of atomic data in spectroscopic analyses of the Sun and metal-poor stars and stellar abundance determinations and new developments in atomic databases and data centers.
A summary of this event will be published shortly, and a well-defined shopping list of atomic data was put forward, namely
- Photoionization cross sections of neutral and singly ionized iron and trans-iron species
- Revision of A-values for the allowed transitions of S II and S III
- Dielectronic recombination of S II and S III
- High-n collision strengths for Li and Na
- Revision of the Ne V IR diagnostics in nebulae
- Atomic data for lowly ionized (singly, doubly and triply) s-process elements: Se, Br, Kr, Rb, Xe, Ba and Pb
