Unveiling the Secrets of Triple Stellar Systems and 'Vampire Stars'

Scientists from the University of Leeds have discovered that some star systems believed to have two stellar bodies may actually have a hidden third star, which acts as a traitorous companion. These "vampire stars" or "Be" stars, surrounded by rings of superheated gas, feed on their companions, pushing them towards each other. The researchers found that Be stars might live in triple star systems rather than double star systems, challenging previous theories. This discovery could transform our understanding of how the most massive stars in the cosmos evolve and provide insights into the formation of black holes and neutron stars.
