[short story collection] Neutron Star is a collection of science fiction short stories by Larry Niven, published in April 1968. The individual stories had been published in the science fiction magazine If in 1966–1967, under Frederik Pohl as editor. ==Contents== The book contains the following eight stories. All stories are situated in Ni...

A neutron star is a type of stellar remnant that can result from the gravitational collapse of a massive star during a Type II, Type Ib or Type Ic supernova event. Neutron stars are the densest and tiniest stars known to exist in the universe; although having only the radius of about 10 km (6 mi), they may have a mass of a few times that of the Su...

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 Unit...

One of the possible endpoints of stellar evolution. A neutron star, with a mass of 1.4 to 3 solar masses, forms from the collapsing core of a massive star immediately following the star's exhaustion of its fusion energy reserves. With the outflow of radiation from the stellar core suddenly switched ...

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 sugar cube of neutron-star stuff on Earth would weigh as much as all of humanity!' Neutron stars can be observed as pulsars.

If a star's mass is too great, its nuclear matter will be compressed beyond the limits given by a white dwarf. The electrons and protons of the star's matter will combine to form neutrons, and the star will in some cases possess regions that are more dense than an atomic nucleus. In a sense, Neutron Stars are like giant atomic nuclei - although the...

The remnant of a very massive star that has undergone a supernova explosion. Neutron stars send out rapidly changing radio emissions and are frequently termed as pulsars.

A neutron star is a star that has collapsed under its own gravity. It is composed solely of neutrons, has a mass of between 1.4 and about three times that of the sun, and a density in excess of 107 kilograms per cubic metre.

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.

The remnant of a dead star after it has exploded in a supernova. Neutron stars are extremely dense and have intense graviational fields, so strong that all atoms are crushed, forcing their nuclei together. Electrons and protons from the smashed atoms are crushed together to form neutrons. Neutron stars are a few kilometres across and have masses c...

A star (approximately sun-sized or larger), a remnant of a supernova explosion, in which gravity has caused all matter to collapse to a giant nucleus, composed only of neutrons. The collapse is also expected to greatly amplify any magnetic field present in the pre-collapse star, as well as speed up enormously any rate of rotation. It is believed th...

Very small, `superdense` star composed mostly of neutrons. They are thought to form when massive stars explode as supernovae, during which the protons and electrons of the star's atoms merge, owing to intense gravitational collapse, to make neutrons. A neutron star has a mass two to three times that of the Sun, compressed into a globe...
