A degenerate star that has been so collapsed by gravity that its electrons and protons have been merged into neutrons by the intense pressure. The solid mass of neutrons is sometimes called neutronium
A dense ball of neutrons that remains at the core of a star after a supernova explosion has destroyed the rest of the star Typical neutron stars are about 20 km across, and contain more mass than the Sun
A compressed star More so, it's a star that is comprised of a few solar masses but they are packed into about 10km of space The density is so high that the matter is only stable as a fluid of neutrons Some predictions say that this object's surface might be as hot as the inside of the sun
A compressed core of an exploded star made up almost entirely of neutrons Neutron stars have a strong gravitational field and some emit pulses of energy along their axis These are known as pulsars
A compact star with a radius of about 10 km and a mass of about 1 5 times that of our Sun A neutron star internally supports itself against gravity by pressure from the strong nuclear force between neutrons, which are uncharged elementary particles commonly found in the nuclei of atoms
The imploded core of a massive star remaining after a supernova explosion Contains about the mass of the Sun in less than a trillionth of the Sun's volume
the collapsed core for an intermediate to high-mass star The core is more than 1 4 solar masses but less than 3 solar masses and is about the diameter of a city The pressure from degenerate neutrons prevents further collapse
A collapsed star of extremely high density Generally these objects have slightly more mass than the Sun, but are only about 10 km in radius A neutron star has intense gravity, and may also have an intense magnetic field and fast rotational component
A compact stellar object that is supported against collapse under self-gravity by the degeneracy pressure of the neutrons of which it is primarily composed Neutron stars are believed to be formed as the end products of the evolution of stars of mass greater than a few (4-10) solar masses
one of the possible endpoints of a star's life A neutron star is a star that has collapsed to a very dense soup of neutrons They are about 10 km in diameter
A neutron star is a star that has collapsed under the weight of its own gravity. A celestial body consisting of the superdense remains of a massive star that has collapsed with sufficient force to push all of its electrons into the nuclei that they orbit, thus leaving only neutrons, and having a powerful gravitational attraction from which only neutrinos and high-energy photons can escape, rendering the body detectable only by x-ray. Any of a class of extremely dense, compact stars thought to be composed mainly of neutrons with a thin outer atmosphere of primarily iron atoms and electrons and protons. Though typically about 12 mi (20 km) in diameter, they have a mass roughly twice the Sun's and thus extremely high densities (about 100 trillion times that of water). Neutron stars have very strong magnetic fields. A solid surface differentiates them from black holes. Below the surface, the pressure is much too high for individual atoms to exist; protons and electrons are compacted together into neutrons. The discovery of pulsars in 1967 provided the first evidence of the existence of neutron stars, predicted in the early 1930s and believed by most investigators to be formed in supernova explosions.

Gravitationally collapsed star of very small dimensions and enormously high density, composed mainly of neutrons that may be the core remnant of a supernova
The imploded core of a massive star produced by a supernova explosion (typical mass of 1 4 times the mass of the sun, radius of about 5 miles, density of a neutron ) According to astronomer and author Frank Shu, "A sugarcube of neutron-star stuff on Earth would weigh as much as all of humanity! This illustrates again how much of humanity is empty space " Neutron stars can be observed as pulsars
A neutron star is composed of neutrons so that's density is about the same as that of an atomic nucleus -- an enormous density A mass of about 1 4 solar masses is packed into a sphere whose diameter is about 10 km Neutron stars are formed as the remnant core of a supernova See NASA's description
A crushed remnant left over when a very massive star explodes Made almost entirely of neutrons (subatomic particles with no electric charge), these stellar corpses pack about twice as much mass as there is in the Sun into a sphere only about 10 kilometers across A teaspoonful of their material would weigh more than all the automobiles in the United States put together Some neutron stars are known to spin very rapidly, at least at the beginning, and can be detected as "pulsars'': rapidly flashing sources of radio radiation or visible light The pulses are produced by the spinning of the neutron star, much like a spinning lighthouse beacon appears to flash on and off
the remnant of a high-mass star The gravity of these stars is strong enough to knock the electrons out of their orbit and into the nucleus of the atoms There, they form with protons to form neutrons The structure of the nucleus is strong enough to resist any further gravitational collapse
