Abstract:
We report variable stars identified in the field of the Galactic open
cluster, NGC 7039. In the fall/winter of 2009, imaging photometry has
been acquired, mainly in the R band, for eight open clusters using the
81 cm Tenagra telescope in Arizona. We present the results for our
first target, NGC 7039. We have found 42 new variable stars and six
suspected variable stars.
Description:
The observations were carried out by using the Tenagra II 32-inch
(80cm) f/7 telescope in Arizona. The eight selected open clusters
mentioned in the Introduction had been monitored from 2009 September
25 to 2009 December 16.
