Researchers, using data from AstroSat, discovered a vampire star (named WOCS 9005) in star cluster M67.
- Vampire Stars, known as Blue Straggler Stars (BSS), defy simple models of stellar evolution and show characteristics of younger stars.
- They rejuvenate by eating up material from a binary companion star in a process known as mass-transfer in a binary system.
