Discovery of a UV bright star population in Globular Cluster NGC 2808
Earth and Space Sciences
Globular clusters are the best laboratories to study the evolution of stars. The globular cluster NGC 2808 was studied in ultraviolet using the Ultraviolet Imaging Telescope (UVIT) on-board AstroSat by a team led by IIST researchers. Using different wavebands (filters), the team discovered the presence of a distinct group of red horizontal branch stars in the cluster, which sheds light on the understanding of multiple populations within the cluster.
