Do we need NLTE in the abundance analysis of solar-type stars?
Maria Bergemann

Over the past decade, enormous progress has been made in our understanding of physical processes in the atmospheres of solar-like stars. One of the most critical additions to the state-of-the-art models is non-local thermodynamic equilibrium (in short, NLTE). I will describe the ongoing efforts to analyze chemical composition of Sun-like stars with NLTE radiation transport models and outline the key results, as well as the major successes and challenges on the way to a more realistic abundance analysis of Sun-like stars.
