Abstract

Absorption lines of some actinides, namely, actinium (Z = 89), protactinium (91), neptunium (93), plutonium (94), americium (95), curium (96), berkelium (97), californium (98), and einsteinium (99), were identified in the spectrum of one of the most peculiar main-sequence stars HD 101065 (Przybylski's star). In the identification we used a high-resolution spectrum (R = 80 000) acquired at the 8.2-m ESO telescope.
