| A survey for southern Delta Scuti variable stars
Twenty-nine field stars have been tested photoelectrically forshort-period variability. Eighteen of these stars have spectral typesbetween A2 and F5 and are not Am stars; of these, six have beendiscovered to be variable and one is a suspected variable. HD 185969,with a period of 0.361 day, has the longest known period for a star ofthe Delta Scuti type. The predominance of discovered variables withamplitudes close to the detection limit is suggestive of most stars inthe instability strip being pulsators.
