HD 213258: a new rapidly oscillating, super-slowly rotating, strongly magnetic Ap star in a spectroscopic binary
Gautier Mathys, Viktor Khalack, Oleksandr Kobzar +2
We report about HD 213258, an Ap star that we recently identified as presenting a unique combination of rare, remarkable properties. Our study of this star is based on ESPaDOnS Sto…
An improved parametric method for evaluating radiative accelerations in stellar interiors
G. Alecian, F. LeBlanc
The single-valued parameter (SVP) method is a parametric method that offers the possibility of computing radiative accelerations in stellar interiors much faster than other methods…
VeSElkA: Vertical Stratification of Element Abundances in CP stars
Viktor Khalack, Francis LeBlanc, Oleksandr Kobzar
A portion of the upper main-sequence stars, called chemically peculiar (CP) stars, show significant abundance anomalies mainly due to atomic diffusion of chemical elements within t…
Project VeSElkA: results of abundance analysis for HD53929 and HD63975
Mamadou L. Ndiaye, Francis LeBlanc, Viktor Khalack
Project VeSElkA (Vertical Stratification of Element Abundances) has been initiated with the aim to detect and study the vertical stratification of element abundances in the atmosph…
Stratification of the elements in the atmospheres of blue horizontal-branch stars
F. LeBlanc, A. Hui-Bon-Hoa, V. R. Khalack
Blue horizontal-branch (BHB) stars with approximately larger than 11500 K show several observational anomalies. In globular clusters, they exhibit low rotational velo…
Vertical stratification of iron in atmospheres of blue horizontal-branch stars
V. Khalack, F. LeBlanc, B. B. Behr
The aim of this study is to search for observational evidence of vertical iron stratification in the atmosphere of fourteen blue horizontal-branch (BHB) stars. We have found from o…
