Project VeSElkA: Vertical Stratification of Element Abundances in CP stars
A new research project on spectral analysis which aims to characterize the vertical stratification of element abundances in stellar atmospheres of chemically peculiar (CP) stars, is discussed in detail. Some results on detection of vertical abundance stratification in several slowly rotating main se...

| description | A new research project on spectral analysis which aims to characterize the vertical stratification of element abundances in stellar atmospheres of chemically peculiar (CP) stars, is discussed in detail. Some results on detection of vertical abundance stratification in several slowly rotating main sequence CP stars are presented and considered as an indicator of the effectiveness of the atomic diffusion mechanism responsible for the observed peculiarities of chemical abundances. This study is carried out in the frame of Project VeSElkA (Vertical Stratification of Elements Abundance) for which 34 slowly rotating CP stars have been observed with the ESPaDOnS spectropolarimetre at CFHT.

We are thankful to the Faculté des Études Supérieures et de la Recherche de l'Université de Moncton and NSERC for research grants. The grids of stellar atmosphere models and corresponding fluxes have been generated using the supercomputer briarree of l'Université de Montréal, that operates under the guidance of Calcul Québec and Calcul Canada. The use of this supercomputer is funded by the Canadian Foundation for Innovation (CFI), NanoQuébec, RMGA and Research Fund of Québec - Nature and Technology (FRQNT). This paper has been typeset from a TEX/LATEX file prepared by the authors. en Головна астрономічна обсерваторія НАН України Advances in Astronomy and Space Physics Project VeSElkA: Vertical Stratification of Element Abundances in CP stars Article published earlier |
