On the thorium absorption lines in the visual spectral domain of supergiants of The Magellanic Clouds
The thorium absorption lines in spectra of the metal-deficient stars: Th-rich Galactic halo star HD221170 and supergiants in the Magellanic Clouds are presented. The identification of Th II lines was performed by comparison of the synthetic spectra with the observed ones for each of the investigated stars. Thorium line Th II 6044.433 Å and a weaker thorium line Th II 6619.943 Å in spectra of red supergiants of the Magellanic Clouds were identified.
