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…
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…
Some evolutionary aspects of the binary stellar systems containing neutron star
O. M. Ulyanov, S. M. Andrievsky, V. F. Gopka +1
The obvious lack of the binary stellar systems that contain neutron stars (NS) is observed at present. Partly it is caused by the fact that it is very difficult to detect neutron s…
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…
Analysis of the spectral energy distribution of the coolest RCrB type carbon star DY Per
L. A. Yakovina, A. V. Shavrina, Ya. V. Pavlenko +1
We analyse the spectral energy distribution of the evolved carbon giant DY Per with a spectral synthesis technique. The red giant shows the photometric features of R CrB type stars…
