δ Scuti pulsations in β Pictoris
Abstract
The discovery of very low-amplitude periodic brightness variations of β Pictoris is reported. Three frequencies in the approximate range 47-53 d-1 could be extracted from four observing runs spanning a week. The character of the variations, together with the high incidence of δ Scuti pulsations in mid A type stars, suggests that β Pic is a member of this class of variable stars.
