We have considered the possibility for modeling of remarkable spectral feature 6708 Å for HD101065 (Przybylski's star) in two ways - as a blend of Li and REE lines and as blend of REE lines only. We show by model calculations that Li lines absorb si

We have shown the possibility for modelling Li blend6708 A, for two roAp stars, HD83368 and HD60435, taking into account lithium spots on the surfaces of these rotating stars. REE spots were also included in calculations. Slow rotating star HD101065

According to the modern theory of the evolution of chemical elements their origin seems understandable for most of the elements, from the lightest up to the heavy ones. For element with atomic number Z=3 (lithium) the situation is following: the phys

We analysed the spectral energy distribution of the evolved carbon star DY Per by spectral synthesis technique. The red giant shows the photometric features of R CrB type stars. We derived the atmosphere parameters of DY Per using three variants of m
