| Abstract : | We have conducted an extensive (∼8 year-long) optical photometric survey of a young open cluster Berkeley 65 (Be65), using the 1.3m Devasthal fast optical telescope. This long term photometric data will be used to study the evolution of low mass stars through their long term multi-band photometric light curve characteristics. We have successfully identified 88 stars as variable stars within Be65. Among them, 67 stars show periodicity in their light curves, while 21 stars are showing irregular behaviour. The periodic variables have periods of a few hours to a few days and amplitude between a few tens of milli-mag to a few hundred milli-mags. Using the color-magnitude and color-color diagrams, we have estimated the extinction, distance, and age of the Be65 cluster as 2.85±0.05 mag, 2.0±0.1 kpc, and 160 Myrs, respectively. In this presentation, we will be discussing the individual characteristics of the variables we have identified in the Be65 cluster. |
