We present the results of a theoretical investigation of the impact of NLTE effects and of granulation inhomogeneities on the iron and oxygen abundances in the metal-poor star HD140283 and in the Sun. Our analysis is based on both the classical one-dimensional (1D) stellar atmosphere models and on a...
