Аннотация: Quantitative analysis of the spectrum HD 108564 is carried out. This is the star of the main sequence of the spectral class K5V, the atmosphere of which is depleted of metals. The high quality observed HARPS spectra were downloaded from the ESO archive. Abundances of elements in the atmosphere were obtained by fit of observational profiles of lines C I and selected lines of molecules C2, O I, Ca I, Si I, Sc II, Cr I, CI, OI, Na I, Mg I, Si I, Ca I, Sc II, Ti I and Ti II, CR I, Mn I, Fe I and Fe II, Co I, Ni I, Cu I, Zn I. Abundances were determined iteratively, with a recalculation of the input parameters, which are the effective temperature Teff at a fixed value of the gravity (or for a fixed Teff). We determined the impact of vatiations of Teff or , which provide the same abundances of A(Fe I) and A(Fe II) on the abundances of other elements. The results obtained indicate an excess of light elements (C, O, Si) to the group of iron. We get the upper limit of the lithium abundance A(Li) |
