Abstract
We report results of high resolution spectroscopic observations of the star s 51Peg and v And. Variations in the shape of different lines are studied i n the light of a recent controversy concerning the existence of a planet or biting around 51Peg. Bisector variations have been noticed for both stars, their shapes and variations are not easily understood, but they do not indi cate any interpretation differing from the now classical interpretation by a planet.
