The spectrum of the roAp star HD 101065 (Przybylski's star) in the Li I 6708 Å spectral region

Abstract

We carried out a detailed analysis of spectra of the unique roAp star HD 101065 (Przybylski's star) near the resonance doublet Li I 6708 Å, using a most complete line list including all possible transitions between REE levels of the NIST database. Our model calculations were performed under two assumptions: a blend of Li and REE lines, and a blend of REE lines only. They prove that Li lines are present in the range Å and that the resulting Li abundance is 3.1 dex (in the scale N(H) = 12.0), while the isotopic ratio is near to 0.3.
