Summary

Story summary

Astronomers present evidence that fast radio bursts originate from binary star systems rather than isolated stars.
Researchers analyzed FRB 220529A using the Five-hundred-meter Aperture Spherical Telescope (FAST) in China for 20 months.
They identified a companion star as the likely source of a rotation measure (RM) flare for FRB 220529A.
The findings support the theory that magnetars in binary systems produce FRBs more often, prompting further studies on prevalence.
