Chinese scientists discover non-accreting neutron star

(ORDO NEWS) — According to a study published in the journal Nature Astronomy, Chinese astronomers have detected a non-accreting and non-radiating neutron star using the Wide Area of ​​Sky Multipurpose Spectroscope (LAMOST), China’s leading optical telescope, Xinhua News Agency reported Sept. 26.

This discovery contributed to the discovery of dense celestial bodies such as neutron stars and black holes, which are difficult to detect.

This will likely contribute to further study of the formation and evolution of stars, as well as the physical properties and theory of the formation of neutron stars and black holes.

Neutron stars are dense celestial bodies formed as a result of the evolution of massive stars until the end of their lives.

A suitable way to detect non-accreting and non-radiating neutron stars is key for astronomers when studying dense celestial bodies.

When using LAMOST to survey the sky, the researchers found a special binary star system, the spectrum of which differs from that of a single star.

After analysis and measurements, the researchers believe that the dense celestial body of the binary star system is a neutron star with a mass of about 1.2 times that of the Sun.

Further radio observations did not reveal either impulsive or constant radiation from the neutron star, which suggests that it is not currently accreting or pulsating.

The research team will use this method to detect denser celestial bodies such as neutron stars and black holes.
