|Unusual neutron star spinning every 76 seconds discovered in stellar graveyard|
by University of Sydney
An international team led by a University of Sydney scientist has discovered an unusual radio signal emitting neutron star that rotates extremely slowly, completing one rotation every 76 seconds.
The star is unique because it resides in the "neutron star graveyard," where no pulsations are expected. The discovery was made by the MeerTRAP team using the MeerKAT radio telescope in South Africa and is published in Nature Astronomy.
The star was initially detected from a single pulse. It was then possible to confirm multiple pulses using simultaneous consecutive eight-second-long images of the sky, to confirm its position.
Neutron stars are extremely dense remnants of supernova explosions of massive stars. Scientists know of about 3,000 of these in our galaxy. However, the new discovery is unlike anything seen so far. The team think it could belong to the theorized class of ultra-long period magnetars—stars with extremely strong magnetic fields.
