«If you have young magnetars that have just been born in supernova explosions, only a few decades old, they could be very bursty objects, have very violent youths, and that could give rise to repeating fast radio bursts,» says astronomer Brian Metzger of Columbia University, who was not involved in the new study.

In the first stage of this process, the more massive star of the pair begins to run out of fuel, transferring its outer layers to its less massive companion — which is destined to become the magnetar — causing it to rotate more and more quickly.

The discovery of the magnetar's former companion elsewhere in the cluster helps solve the mystery of how a star that started off so massive could become a magnetar, rather than collapse into a black hole.
