Open clusters are physically related groups of stars held together by mutual <br /> <br /> <br /> <br /> <br /> gravitational attraction, populating a limited region of space. Photometric <br /> <br /> <br /> <br /> <br /> observation of open clusters allow us to study several kinds of variable stars in much <br /> <br /> <br /> <br /> <br /> more details. Variable stars are stars with variability in brightness. This variability <br /> <br /> <br /> <br /> <br /> is due to external and internal factor. <br /> <br /> <br /> <br /> <br /> I present results of a search for variable stars in the open cluster NGC 6716. <br /> <br /> <br /> <br /> <br /> Imaging photometry has been acquired in Bosscha Observatory, Lembang, using <br /> <br /> <br /> <br /> <br /> Celestron 11 inch (f/10) Schmidt-Cassegrain telescope equipped with CCD SBIG <br /> <br /> <br /> <br /> <br /> ST-8 XME as the detector. The data were processed using software Image <br /> <br /> <br /> <br /> <br /> Reduction and Analysis Facility (IRAF) and Light Curve and Period Analysis <br /> <br /> <br /> <br /> <br /> Software (Peranso). As result, I found 15 variable star candidate. Among the <br /> <br /> <br /> <br /> <br /> variable stars, one star confirmed to be RR Lyrae and one is a probable d Scuti. <br /> <br /> <br /> <br /> <br /> Moreover, I found one eclipsing W UMa system.
