Detailed explanation-1: -Neutron stars have a radius on the order of 10 kilometres (6 mi) and a mass of about 1.4 solar masses. They result from the supernova explosion of a massive star, combined with gravitational collapse, that compresses the core past white dwarf star density to that of atomic nuclei.

Detailed explanation-2: -At least some supernovae leave behind a highly magnetic, rapidly rotating neutron star, which can be observed as a pulsar if its beam of escaping particles and focused radiation is pointing toward us. Pulsars emit rapid pulses of radiation at regular intervals; their periods are in the range of 0.001 to 10 seconds.

Detailed explanation-3: -Supernovae occur at the end of a massive star’s life, when it is a red supergiant, with its nuclear fuel almost spent. When the central core becomes so dense that electrons and protons begin to form neutrons, it collapses catastrophically to form a neutron star.

Detailed explanation-4: -Pulsars are rapidly spinning neutron stars, extremely dense stars composed almost entirely of neutrons and having a diameter of only 20 km (12 miles) or less. Pulsar masses range between 1.18 and 1.97 times that of the Sun, but most pulsars have a mass 1.35 times that of the Sun.

Detailed explanation-5: -A neutron star forms when a medium-sized star reaches the end of its life and explodes as a supernova, after which it leaves an incredibly dense core behind. The name ‘neutron star’ comes from the sub-atomic particles called neutrons, which you usually find inside the nuclei of atoms.
