Asteroseismology has the potential to provide new insights into the physics of stellar interiors .
We have obtained UVES high time resolution observations of the \delta Scuti star HD 21190 and of the Ap Sr star HD 218994 to search for pulsational line profile variations .
We report the discovery of a new roAp star , HD 218994 , with a pulsation period of 14.2 min .
This is one of the most evolved roAp stars .
No rapid pulsations have been found in the spectra of the cool Ap star – \delta Scuti star HD 21190 .
However , we detect with unprecedented clarity for a \delta Sct star moving peaks in the cores of spectral lines that indicate the presence of high degree non-radial pulsations in this star .
