O článku:
We present the results of our recent search for pulsational line profile
variations in high
time resolution UVES spectra of the most evolved Ap star known, the
δ Scuti star HD 21190, and of the Ap Sr star HD 218994.
We found that HD 218994 is an roAp star with a pulsation period of
5.1 min, which makes it the 36th star known to be a roAp star.
No rapid pulsations have been found in the spectra
of the δ Scuti star HD 21190. However, we detect moving peaks
in the cores of spectral lines,
which indicate the presence of non-radial pulsations in this star.
