Abstract
Synthetic spectrum of the peculiar roAp star HD 101065 (Przybylski’s Star) have been computed in the wavelength interval 6705.8–6708.7 A in order to describe the observed spectrum in the vicinity of the 6708 A lithium line. Our detailed computations of the synthetic spectrum allowing for the hyperfine structure of the lithium line, lithium isotopic composition, and blending due to lines of rare-earth elements (CeII, NdII, SmII, and others) have yielded estimates of the atmospheric lithium abundance of the star and its 6Li/7Li isotopic ratio.
