O článku:
We present the results of our analysis of the vertical element stratification
in the atmospheres of 9 roAp stars. Using high resolution observations
(R≈100 000) obtained with the ESO-VLT spectrograph UVES and state
of the art model atmosphere and spectral synthesis codes, we analysed the
inhomogeneous vertical distribution of Mg, Si, Ca, Cr, Fe and Sr in
10 Aquilae (HD 176232) and Fe stratification in the whole sample. We present
the derived vertical abundance map of 10 Aquilae's atmosphere and compare our
findings with Fe stratification profiles of all roAp stars.
