CCD photometry of variable stars in the field of the globular cluster NGC 6397.

KALUZNY J.

Abstract (from CDS):

The 13.6x13.6arcmin2 field including the central part of the globular cluster NGC 6397 was surveyed in a search for short-period variable stars. We obtained light curves for 6 close binaries, 2 SX Phe stars and 1 RR Lyrae variable, 7 of which are new discoveries. Both identified SX Phe variables are likely members of the cluster. One of the identified eclipsing binaries is most probably a field star while for the remaining 5 binaries our data do not preclude cluster membership. A V vs. B-V color-magnitude diagram extending from the tip of the red giant branch to below the main-sequence turnoff is presented.
