AstroSat’s Ultraviolet Imaging Telescope spots rare ultraviolet-bright stars in a massive intriguing cosmic dinosaur in the Milky Way

Findings
  • It is said to have at least five generations of stars have spotted rare hot UV-bright stars in it.
  • These stars whose inner core is almost exposed, making them very hot, exist in the late stages of evolution of a Sun-like star.
  • It is not clear how these stars end their lives as not many of them are detected in these fast-evolving phases, making their study crucial.
  • Astronomers distinguished the hot UV-bright stars from the relatively cooler red giant and main-sequence stars which appear dim in these images. 
  • About 34 UV-bright stars were found to be members of the globular cluster. From the data, the team derived the properties of these stars such as their surface temperatures, luminosities and radii.
