Discovery of UV bright stellar population candidates in NGC 5053 using AstroSat-UVIT

Globular clusters are known to serve as fundamental test beds for stellar evolution theories. NGC 5053, a metal-poor and a rather dispersed globular cluster, was studied in the ultraviolet regime with AstroSat's Ultra Violet Imaging Telescope (UVIT). The images of the cluster were analyzed in various filters across the FUV and NUV bands by a team led by IIST researchers. The team discovered eight blue straggler candidates, six evolved blue straggler candidates, and an extreme horizontal branch candidate among the cluster's new probable UV bright population.
