Observ. of Odessa National Univ., Astroph. et Spectrosc., Univ. de Mons-Hainaut, IPNA | | Abstract: | We carried out a detailed analysis of spectra of the unique roAp star HD 101065 (Przybylski’s star) near the resonance doublet Li I 6708 A, using a most complete line list including all possible transitions between REE levels of NIST database. Our model calculations were performed under two assumptions: blend of Li and REE lines, and blend of REE lines only. They prove that Li lines are present in the range 6707.72-6708.02 AA, and that the resulting Li abundance is 3.1 dex (in the scale log N(H) = 12.0, while the isotopic ratio 6Li/7Li is near to 0.3. | | Source: | arXiv, astro-ph/0307464 | | Services: | Forum | Review | PDF | Favorites | |
