| Summary: | 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. |
