Scientific paper

A photometric study of stars in the lower part of the instability strip of the southern open cluster NGC 2516 has been performed in order to detect the incidence of short-period variability of Delta Scuti type. A new statistical method of data analysis has been introduced for identifying variable and constant stars. The preliminary results of the observations for NGC 2516 have been compared with those known for other clusters. It seems that there is a normal incidence of short-period variable stars. On the other hand, several variable stars with small amplitude and rather long periods (spotted rotating variables?) have been found, all lying near the cold border of the instability strip. Such a high incidence of 'long'-period variability in the lower part of the instability strip has never been found in any other cluster.
