[22.02] Delta Scuti Variables in the Field of NGC 6882/85

In the constellation Vulpecula reside two open clusters NGC 6882 and NGC 6885. The smaller cluster NGC 6885 is superimposed onto NGC 6882. Recent observations of the field have led to discoveries that challenge the current classification of these two clusters. We present the results from a variable star campaign of regions surrounding the heart of the cluster that resulted in the discovery of four new \delta Scuti stars and five other candidates. Of the four, one star was found to be a high amplitude pulsator with a period of about 0.205557 days. The remaining candidates consist of low amplitude stars of which two were found to undergo rapid pulsations. The observations were performed utilizing an application of time series CCD photometry using VRI Bessel filters. Data were obtained using the 0.4-m David Derrick Telescope.

Funding for this research was provided by the National Science Foundation Research Experience for Undergraduates program hosted by the Dept. of Physics and Astronomy at Brigham Young University.
