Date and Time of Talk

Open clusters provide a unique environment for investigating the behavior and characteristics of different types
of variable stars. By observing variable stars within open clusters, astronomers gain insights into the intrinsic
properties, evolution, and physical processes governing the stars. This research work explores the significance
of open cluster studies in enhancing our comprehension of variable stars, highlighting the advantages of using
open clusters as natural laboratories for stellar variability research. Our study was based on combining
observations from both ground-based telescopes and space-based observatories. The data collection covered
only optical bands. Our study aims to identify different types of variable stars and explore their behavior using
photometric data from various sources. Photometric data collected over extended time frames provides
valuable information on their periodicities, and rotational periods. We explored potential connections between
photometric variability and other intrinsic properties, such as age and mass, to unravel the underlying
mechanisms governing the life cycles of these stellar populations. The light curves of identified variables were
analyzed, and their properties were compared with the data from GAIA DR3 and TESS missions.
In this work, we present the study of the stellar variability towards the young open cluster NGC 7209 and NGC
1983, focusing on the data analysis and methodology in our research work.
