AstroSat helps spot rare UV-bright stars in a massive cosmic dinosaur in the Milky Way
Astronomers exploring the massive intriguing globular cluster in our Galaxy called NGC 2808 that 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. A false colour image of the globular cluster NGC 2808 obtained using AstroSat/UVIT. The stars as seen using far-UV (FUV) filter are shown in blue colour, and the yellow colour is used to show the stars observed in near-UV (NUV). Motivated by the fact that old globular clusters referred to as dinosaurs of the universe present excel...
