The Secret of Massive Stars Found Far From Their Birthplace in Milky Way’s Disk
Astronomers have found an explanation for the strange occurrence of massive stars located far from their birthplace in the disk of our Milky Way Galaxy: the secret seems to lie in the merging of medium-mass stars, specifically HD 93521, a Population I massive O-type star 3,000 light-years above the galactic plane that was ejected on a 39-million year journey either through dynamical interactions or a result of a supernova in a binary system.
