What is a Neutron Star?

A neutron star is the most dense star besides a black hole. The star evolved to the end. After a supernova explosion through gravity collapse, it may become one of the few end points. Stars that have not reached the mass that can form a black hole collapse at the end of life A star body between white dwarfs and black holes, which is considerably more dense than any material on Earth.

Soon after neutrons were discovered by Chadwick in 1932, Soviet physicist Landau proposed that a class of stars could be composed of all neutrons. Landau became the first scholar to propose the concept of neutron stars.

In 1934,

The predecessor of a neutron star is generally a star with a mass of 10-29 times the mass of the sun. The tremendous pressure it produced during the collapse of the explosion caused huge changes in its material structure. In this case, not only the shell of the atom was broken, but also the

The neutron star is not the final state of the star, it has to evolve further. Due to its high temperature and fast energy consumption, it maintains luminosity by slowing down its rotation to consume angular momentum. When its angular momentum is consumed, the neutron star will become non-luminous

As a neutron star, neutron stars have many very unique properties that have opened our eyes. Because they are never reachable in the earth laboratory, so that we have a deeper understanding of some of the nature of stars. In summary, these properties are:

The area of a neutron star is about 30-300 square kilometers, and the earth is 510 million square kilometers. The area of the earth is about 17-17 million times that of a neutron star.

Pulsar

The surface temperature of a neutron star is about 1.1 million degrees. It emits X-rays,

Gravitational wave research

At 22 o'clock on October 16, 2017, Beijing time, the National Science Foundation held a press conference to announce that the Laser Interference Gravitational Wave Observatory (LIGO) and Virgo Gravitational Wave Observatory (Virgo) first discovered the double neutron star and In conjunction with the gravitational wave event, the International Gravitational Wave Electromagnetic Correspondence Observation Union discovered the electromagnetic counterpart of the gravitational wave event. ^[6]

Source of heavy metal elements

Scientists believe that gold, platinum, and other heavy metal elements on Earth may have come from a big explosion in which neutron stars collided hundreds of millions of years before the birth of the solar system.

It has long been believed that ordinary elements such as oxygen and carbon were generated when a dying star exploded into a nova, but researchers are puzzled by the data that these star explosions cannot produce as much as they exist on Earth Heavy metal element. These scientists from the University of Leicester in the United Kingdom and the University of Basel in Switzerland believe that the answer lies in rare neutron star pairs.

Neutron stars are the ultra-high-density cores that generate new types of large stars. They contain as much material as our sun, but only about the size of a city. Sometimes it is found that two neutron stars are orbiting each other and orbiting each other. This is a relic of the double galaxy. There are four pairs known in our galaxy. Scientists used supercomputers at the Leicester Astrophysics fluidic equipment 100 miles north of London, England, to do simulations. If they were rotated slowly and approached an explosion, what would be the result of such a huge gravity.

It takes weeks for supercomputers to perform such calculations, and this is only what happened in the last few milliseconds of the lifetimes of the two planets. The results show that as neutron stars approach, huge forces split them apart, releasing enough energy to illuminate the entire universe for a few milliseconds. This collision is more likely to produce a black hole-a rip that engulfes light in space-and ejects ash when a nuclear reaction occurs, injecting protons into the nuclei of light elements to generate heavy elements. The ejected material mixed with the gas and dust between the stars and collided to form a new generation of stars, slowly dispersing heavy metals in the Milky Way.

The odds of this rare phenomenon appearing in the universe is more than 10 billion years, which is consistent with our analysis of elemental spectra in the solar system, which has a life of 5 billion years, providing a powerful theory evidence of. The amazing thing is that the number of elements produced by the model is very close to the universe, and it partially answers the question of where our world comes from. ^[7]
