Spectral analysis and abundances of the post-HB star HD 76431
V. Khalack, B. Yameogo, F. LeBlanc +4
HD76431 is a slow rotating post-HB star that shows an underabundance of helium by 0.5 dex relative to the solar value. These observational facts suggest that atomic diffusion could…
The analysis of lithium in HD166473
A. V. Shavrina, V. Khalack, Y. Glagolevskij +4
The analysis of Li I 6708A line was performed for 6 rotational phases distributed over the whole rotational period (9.5 years) of HD166473. The magnetic field model was constructed…
Spots structure and stratification of helium and silicon in the atmosphere of He-weak star HD 21699
A. V. Shavrina, Yu. V. Glagolevskij, J. Silvester +3
The magnetic star HD 21699 possesses a unique magnetic field structure where the magnetic dipole is displaced from the centre by 0.4 +/- 0.1 of the stellar radius (perpendicularly…
