What is Neutron star ?
Neutron star are the very small (10 km radius in diameter sized ) star having density more than sun . They are called neutron star because their particle only contain neutron of atom . They do not have any other material .
How Neutron star born ?
When a giant star dies due to the supernova explosion then they collapsed and all material,element of star converts into neutron after melting .
A stellar phoenix
When stars ten times massive and larger than sun explode in a violent supernova explosion , their outer layers blow off emitting very bright light , leaving behind small, dense core that continues to collapse until all matter converts into neutron. Gravity presses the material in on itself so tightly that protons and electrons combine to make neutrons . So they are called “neutron star.”
After formation of neutron star they continue collapsing itself and finally they became black hole which is thousand time denser than neutron star .
