On the Spectrum of Extremely Metal-Poor Star HD 52961
High resolution spectra of the extremely metal-poor star HD 52961 are investigated. The atmospheric parameters found are: Teff = 6000 ± 100 K, log g = 0.5±0.5, ξt = 6.8 km s−1, [Fe/H] = −4.50±0.20. The carbon abundance is close to the solar one, [C/H] = −0.17±0.12. At the same time abundances of hea...
