Characterized as one of the possible final stages of stellar evolution, neutron stars are celestial bodies that form through the thermonuclear explosion of stars with a mass eight times greater than of the sun.
This phenomenon is a consequence of nuclear fusion, where all the hydrogen is consumed and the helium undergoes a long process of transformation (millions of years) until it reaches iron. As a result, the core becomes so dense that it cannot support its own weight, and releases an enormous amount of energy, which causes the “destruction” of the star.
This explosion promotes the junction of protons and electrons, forming extremely compact and dense celestial bodies, there is no longer the presence of atoms, but a large cluster of neutrons, that is, the neutron stars.
The main characteristics of neutron stars are: large nucleus and formed mainly by neutrons, very massive (solid matter), high gravity, very low radiation, extremely fast rotation period, high density, very magnetic field strong, etc.
