The chemical composition of a star is deduced from its spectrum derived from its stellar atmosphere. Significant results have been achieved in the past few years, making use of rapid advances in different areas, i.e. observations, analysis of the data, development of increasing sophisticated models, that all contribute to better diagnostics of the stellar atmospheres. In parallel, an important need of atomic data arises in order to characterize in details the chemical composition and the physical conditions of the observed stars. Our project proposes an interdisciplinary strategy, combining new developments in experimental or theoretical laboratory works in view of the best interpretation of the observed stellar spectra.As
