Scientists discovered the slowest neutron star

This star-rookie, which is 14 million-year-old and located in the constellation of Kassiopi, revolves around itself once every 23.5 seconds. The record of the slowest pulsar has so far held a neutron star that made a rotation every 8.5 seconds.

The record of the fastest pulsar holds a star that makes a spin at just 1.4 milliseconds. So the slowest pulsar turns around 15,000 times slower than the fastest, which has impressed scientists who did not expect to find such a … lazy neutron star.

“This pulsar was totally unexpected. We are a bit shocked that a neutron star can rotate so slowly and nevertheless generate powerful radio pulses. Obviously, the pulsars may be slower than we thought, which obliges us to review our theories about them, “said researcher Jason Hesselles of the Netherlands Institute for Radio Astronomy ASTRON and the University of Amsterdam.

The researchers, who made the discovery with the LOFAR telescope in the Netherlands, made a relevant publication in the Astrophysical Journal of Astrophysics.  The pulsars rotate like spinning rods and produce electromagnetic radiation in the form of rays, which are visible on Earth, such as the light of the lighthouses by the ships (which is why the stars are also called “cosmic beacons”).

Pulsars are created when a large star explodes as super-vow and remains after a rapidly rotating sphere of very high density, with a diameter of only 20 km.
