Researchers discover rare star system that emits radio signals every 8 minutes

Scientists at Curtin University have discovered a rare star system called GPM J071507−114153, consisting of a white dwarf and a Sun-like star orbiting each other, which emits radio signals every eight minutes. This is the first time radio pulses have been detected from a white dwarf paired with a Sun-like star, breaking new ground as such pulses are typically only observed in systems with smaller red dwarf stars. The discovery allows astronomers to confirm that the radio emissions originate from the white dwarf region and has revealed additional details like stellar flares and magnetic activity on the companion star.
