Abnormal lithium abundance in several Ap-Bp stars
A. Shavrina, N. S. Polosukhina, N. A. Drake +4
Using observations of rapidly rotating roAp star HD 12098, obtained with 6m telescope of SAO RAS in 2005-2008 in nine rotational phases (0.001-0.817), and code V. Tsymbal ROTATE we…
Multi-element Doppler imaging of the CP2 star HD 3980
N. Nesvacil, T. Lüftinger, D. Shulyak +8
In atmospheres of magnetic main-sequence stars, the diffusion of chemical elements leads to a number of observed anomalies, such as abundance spots across the stellar surface. The…
Lithium and its isotopic ratio 6Li/7Li in the atmospheres of some sharp-lined roAp star
A. Shavrina, N. Polosukhina, S. Khan +10
The lines of lithium at 6708 A, and 6103 A, are analyzed in high resolution spectra of some sharp-lined and slowly rotating roAp stars. Three spectral synthesis codes - STARSP, ZEE…
Stellar abundance patterns. What is the possible level of completeness today ?
V. Gopka, A. Yushchenko, F. Musaev +6
We discuss the way of increasing of the number of chemical elements, investigated in stellar spectra. We can reach it by using spectrum synthesis method, new atomic data and observ…
The spectrum of the roAp star HD 101065(Przybylski's star) in the Li I 6708 A spectral region
A. V. Shavrina, N. S. Polosukhina, Ya. V. Pavlenko +8
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 includin…
The Enigma of Lithium: from CP Stars to K Giants. First Results of CP Star Observations Obtained at Mount Stromlo Observatory
N. S. Polosukhina, N. A. Drake, M. Hack +3
We present the results of the observations of some roAp stars made at Mount Stromlo Observatory during 17 nights in 2001 September-October. This long observing run permitted us to…
