The 'extremely unusual' neutron star poses a mystery

The 'extremely unusual' neutron star poses a mystery

Scientists The Universities of Manchester, Oxford and Sydney They discovered a neutron star that differs from all other stars of its class. Accordingly, it rotates at an unprecedented slow speed, Slower than all 3,000 other neutron starsthat have been observed so far.

Neutron stars actually rotate Very fast. Many people just need it Seconds Or even just parts of it to rotate completely around its axis. The star now discovered from which… The university in a statement Reports and sends signals at intervals 54 minutes Out of place.

“Very unusual”

“It is highly unusual to discover a candidate neutron star emitting radio waves in this way,” says the lead author. Manisha Kaleb From the University of Sydney. The astrophysics professor says this discovery shows how space exploration using a new generation of radio telescopes can lead to surprises and challenge our understanding of the universe. Ben Stubbers Quoted.

The data comes from a range of telescopes ASKAP in Australia And Meerkat in South Africa. The results were published in Nature Astronomy Journal.

How are neutron stars formed?

Neutron stars form when stars shed their outer shells at the end of their lives. In the result Supernova The star's core collapses. The pressure is so strong that even atoms can no longer withstand it. Electrons And Protons Then merge together NeutronsSo, which one? Neutron star formation.

The unusual object has now almost been discovered 16,000 light years away from the ground. Her name ASCAP J1935+2148. The radiation indicates that it is just a neutron star.

White dwarf?

Scientists do not completely rule out the possibility that the signal also comes from one White dwarf could come from. They also arise from dead stars, but not in this active way. they “Burned“Stars. They are much larger than neutron stars, but less dense.

Neutron stars have a diameter of about approx 20 kmBut at the same time it has a mass similar to our Sun. So it is very dense. White dwarfs, on the other hand, are roughly the size of Earth. According to the researchers, the data recorded by ASKAP J1935+214 would be better for a neutron star. Further investigation is needed to confirm the authenticity of the object.
