Abundances of elements of the Fe-group in metal-poor stars.
Abstract
The paper presents results of an analysis of the abundances of elements of the Fe group and Si in 19 field stars with Fe/H ranging from -2.7 to -0.2. The hyperfine structure is fully considered for lines of the odd elements. The abundances in metal-poor stars are compared with the predictions of nucleosynthesis theories for Fe group elements. A promising agreement with recent calculations for production of these elements by type II SNe is obtained.
