Abstract

Ages of Stellar clusters can be determined both qualitative and quantitative perspective. Stellar clusters observations show different types of stars while they are thought to have a similar generational origin. From a quantitative perspective, an isochrone (“Same age”) are used to fit individual stars on a color magnitude diagram. We observed three stellar clusters using the Skynet Robotic Telescope and demonstrated their respective differences in age. Stellar colors were calibrated with standard filters and BVRI and compared them against catalogs with proper motions and distances. An isochrone was used to fit the individual stars for each cluster to quantify four parameters – age, distance, metallicity and extinction. We compared these parameters to published values and found good agreement.
