Abstract: 

The unusual main-sequence star HD 101065 (Przybylski's star) were analyzed to identify the lines of actinides in its spectrum: actinium (Z = 89), protactinium (91), neptunium (93), plutonium (94), americium (95), curium (96), berkelium (97), californium (98), and einsteinium (99). The high-resolution spectra (R = 80.000) obtained at the 8.2-m ESO telescope were used.
