Abstract

The main goal of the project is to determine the dependence between lithium and beryllium abundance and different stellar parameters in a sample of about 200 field solar analogs and 18 solar twins from old open clusters. The results will be essential for the study of material transport in stars and models of stellar interiors. (AU)
