Astronomers using Japan's XRISM space telescope have identified a hidden white dwarf companion as the source of Gamma Cassiopeiae's unusually intense X-rays, solving a mystery that has puzzled scientists for 50 years. The discovery, led by University of Liège researchers, confirms the existence of a long-predicted class of binary star systems and suggests revisions to models of binary star evolution.
