«Several interpretations of the nature of this system have been proposed, from an isolated slowly
spinning magnetar with a substantial fossil - disk, to a young low mass X-ray binary system, or even a binary magnetar, but none of them is straightforward, nor can they explain the overall observational properties,» researchers said in a study, published in the Sept. 2, 2016, issue of The Astrophysical Journal Letters.

They concluded that the supernova may be powered by a rapidly
spinning dead star called a
magnetar.
Also, the
spin rate of SN 2017egm's
magnetar may be slower than usual.
«When it ultimately died, the collapsing core could have
spun up a
magnetar like a giant top.
The new study finds that the supernovae are likely powered by the creation of a
magnetar, an extraordinarily magnetized neutron star
spinning hundreds of times per second.
The
spin rate of the
magnetar may also be slower than average.
However, 1E 1613's slow
spin remained a mystery with its source rotating once every 24,000 seconds (6.67 hours), compared to other known slow
magnetars that
spin around once every 10 seconds.
