ROAstronomers have identified the source of mysterious radio signals known as 'long-period radio transients' (LPTs) in the Milky Way galaxy. These powerful radio pulses repeat at unusually long intervals, ranging from several minutes to hours. Until now, only a few such objects had been detected, and their origins remained unclear. Proposed explanations included slowly rotating neutron stars or binary systems consisting of a white dwarf and a companion star, but none were confirmed. An international team led by researchers from the University of Sydney has provided the most compelling explanation yet, using data from the Australian SKA PathFinder (ASKAP) telescope. They studied an object called ASKAP J1745-5051, which consists of a white dwarf and a red dwarf star orbiting each other every hour and a half. The research suggests that the radio signals originate from magnetic field interactions between the two stars, while X-ray emissions come from heated material being pulled by the white dwarf. This discovery could serve as a 'Rosetta Stone' for understanding these enigmatic phenomena.
