Neutron stars are usually the remnants of supernova explosions, and their rotation rate is as fast as hundreds of revolutions per second. However, scientists have recently discovered neutron stars in the “neutron star cemetery” region of the universe that only rotate once every 76 seconds.

Scientists have never found any neutron stars in the Vela-X 1 region of the Milky Way in the past, so this region is divided into a neutron star cemetery. There are currently about 3,000 known neutron stars in the Milky Way. No one thought that they would dig up supernova remnants here. However, when the University of Sydney team used the MeerKAT radio telescope to observe the Vela-X 1 region about 1,300 light-years from Earth, they found a strange pulse lasting about 300 milliseconds.

After confirming more radio signals and their locations, the researchers found that the source of the signal was a neutron star named PSR J0901-4046. But unlike any neutron star seen so far, the longest known rotation period of a pulsar was 23.5 seconds, and most neutron star pulses cycle every few seconds or even milliseconds, but PSR J0901-4046 broke a record of 76 seconds – researchers It is thought that it is likely to be a theoretical ultra-long-period magnetar, that is, we may discover entirely new radio-emitting objects.

The emergence of PSR J0941-4046 challenges scientists’ understanding of the birth and evolution of neutron stars. In addition, it seems to produce at least 7 distinct pulse shapes, which may be related to some unknown physical mechanism. It is uncertain how many neutron stars of this type exist in the Milky Way. But it’s worth our continued search.

The new paper was published in the journal Nature Astronomy.
