Astronomers Discover Neutron Star Defying Known Physics with 6.5-Hour Spin

The unusual neutron star ASKAP J1839-0756 challenges existing theories by emitting radio pulses despite its extremely slow rotation.

  • ASKAP J1839-0756, located 13,000 light years away, spins once every 6.5 hours, far slower than typical neutron stars.
  • Neutron stars are known for their rapid spins, and current theories suggest they should stop emitting radio waves at such slow speeds.
  • This object emits radio pulses from both magnetic poles, a rare phenomenon that provides unique insights into its structure and behavior.
  • Astronomers speculate the star might be a magnetar, but its characteristics push the boundaries of known magnetar behavior.
  • The discovery was made using Australia's ASKAP radio telescope, highlighting the potential for future breakthroughs with upcoming telescopes like SKA-Low.
