The aim of the ASOS conference is to bring together scientists from atomic physics, plasma physics and astrophysics and to bring together the “producers” of fundamental atomic data and the “users” of this data. During the conference, atomic physicists present the development of their theoretical and experimental methods and the possibility of obtaining increasingly complete and precise data on the structures and the radiative and collisional properties of atomic systems. Astrophysicists and plasma physicists review the context of their research and their needs for atomic data for modelling the plasmas studied, such as stellar or solar plasmas, fusion plasmas or other laboratory plasmas.

 The conference will be held on the campus "Les Cordeliers" of Sorbonne Université, located at 15, rue de l'Ecole de Médecine, 75006 Paris.
