For a decade, scientists detected mysterious radio signals from space, which were traced to a binary star system consisting of a white dwarf and a red dwarf. These stars, orbiting closely, create regular radio pulses as they interact magnetically, producing a signal every 125 minutes. Located 1,600 light-years away in the constellation Ursa Major, this system, ILTJ1101, represents the first observed source of such pulses outside of magnetars. This discovery opens avenues for understanding more potential signals from binary systems in the universe.
"The radio pulses are very similar to FRBs, but they each have different characteristics, making this discovery a unique addition to our understanding of cosmic phenomena."
"This is the first time that a repeating long radio pulse has been observed coming from anything other than a highly magnetised neutron star, known as a magnetar."
