Chemical Elements as Tracers of the Evolution of the Cosmos

WG3 : 3D NLTE

This is a long term project with several subprojects aimed at the development and implementation of 3D NLTE techniques and tools for stellar abundance analysis

Project leads: Arūnas Kučinskas, Andreas Korn

Team members: S. Andrievsky, P. Bonifacio, E. Caffau, A. Gallagher, C. J. Hansen, J. Klevas, S. Korotin, H.-G. Ludwig, M. Steffen, S. Wedemeyer

Rationale: This a long-term project aimed at further development and implementation of 3D model atmospheres and NLTE spectral analysis tools in studies of chemical composition of stars and stellar populations. Amongst the main goals of the project is the assessment of the needs of astronuclear community related to the application of 3D hydrodynamical model atmospheres and the NLTE abundance analysis techniques in the studies of chemical composition of stars; and the development of the 3D hydrodynamical model atmospheres as well as 3D NLTE techniques and tools for stellar abundance analysis.
