Impact of NLTE on determinations of atmospheric parameters and chemical abundances of very metal-poor stars

Abstract

Based on high-resolution spectral observations for a sample of very metal-poor stars, we investigate how well stellar chemical abundances can be derived with available theoretical methods and computational tools.
