Astronomers have spotted a red dwarf star in a system that is almost certainly the source of a radio signal that, for a while, repeated once every 125 minutes. Moreover, there’s evidence of a white dwarf companion.

Astronomers have traced a starnge blast of radiowaves that repeats every 2 hours back to a dead star white dwarf magnetically slamming its stellar companion.

Astronomers have finally traced mysterious radio pulses in the Milky Way to a unique cosmic duo—a red dwarf and a white dwarf orbiting each other every two hours. This discovery challenges previous assumptions that only neutron stars produce such signals.

Astronomers detected constant stream of radio pulses emitted from across the galaxy. Team now finds the pulses are from a white dwarf and red dwarf binary. The stars’ orbit is so tight that their magnetic fields interact,
