New discovery about the formation of neutron stars

Scientists at the University of Alberta (Canada) have discovered a new cause of the formation of young neutron star about 330 years ago.

According to scientists, the neutron star is formed by the burst of X-rays from the explosion of Cassiopeia A (a star about 20 km in diameter, 11,000 light-years from Earth and exploded in a time now about 330 years).

Previously in 1999, the Chandra X-ray astronomical telescope, the US Aerospace Agency (NASA), discovered for the first time the stellar explosion Cassiopeia A. However, at that time scientists There has not yet been a model to explain the phenomenon of X-ray spectra emitted from this explosion.

Scientists at that time explained that because the planet's radius was so small, it could not produce a neutron star. There is also an opinion that because its surface temperature is uneven, the explosion does not make much sense.

However, in this new study, astronomers have combined previous research data and found that it was the model that emitted X-rays after the explosion of Cassiopeia A, which led to Neutron star formation. The current.

When stars are formed, the temperature around it is so high that the surface of the neutron star changes dramatically, according to Craig Heinke, an astrophysicist at the University of Alberta. That explains why the magnetic effect of neutron stars is not large and the carbon atmosphere is very thin.
