Researchers have made a groundbreaking discovery of a vampire star in the star cluster M67 located in the constellation Cancer, that has been rejuvenating its youth by sucking up material from a companion.  The study provides rare insights into the binary star evolution process and provides an important missing link in the rejuvenation in these stars. This discovery experimentally confirms the theoretical prediction that the vampire stars are formed by acquiring polluted matter through transfer from their companion, leaving behind a remnant white dwarf. The rarity of such chemically polluted systems is still a mystery and the team thinks that it may be due to the quick settling of the pollutants in the atmosphere of the vampire stars.
