Whats is a neutron star made of?

Answer 1

Neutron stars are compact objects that are created in the cores of massive stars during supernova explosions. The core of the star collapses, and crushes together every proton with a corresponding electron turning each electron-proton pair into a neutron. The neutrons, however, can often stop the collapse and remain as a neutron star.

Neutron stars are fascinating objects because they are the most dense objects known. They are only about 10 miles in diameter, yet they are more massive than the Sun. One sugar cube of neutron star material weighs about 100 million tons, which is about as much as a mountain.

Like their less massive counterparts, white dwarfs, the heavier a neutron star gets the smaller it gets. Imagine if a 10 pound bag of flour was smaller than a 5 pound bag!

Neutron stars can be observed occasionally, as with Puppis A above, as an extremely small and hot star within a supernova remnant. However, they are more likely to be seen when they are a pulsar or part of an X-ray binary.

Answer 3

A neutron star is basically an atomic nucleus more massive than the sun. But instead of being held together by nuclear foreces, it's held together by intense gravity. The protons and electrons of the original star's core combined while collapsing (during a supernova) to create a star made completely of neutrons, the size of a city, and a density of 100 million tons per cubic centimeter.

Answer 4

Good question: We dont entirely know (!)

The best model (and most modern, as I recall) is this: the surface consists of neutrons (through neutron degeneracy pressure, which is the intense pressure everyone is speaking of), and the deeper one goes, the less certain we are. Many people hypothesize that there is a neutron superfluid in there; some have bravely stated that there are vortices running vertical, parallel with the axis of rotation right through the star. In the very core, it's completely up for grabs right now. Perhaps we might find out soon? I'd love to know, they're fascinating objects!

Answer 5

Neutrons and a lot of loving.

Answer 6

Neutrons. The pressure is enough to cause the electrons in each atom to combine with the protons, leaving only neutrons. One electron when combined with one proton makes one neutron.

Answer 7

A neutron star is one of the few possible outcomes of stellar evolution, formed by the collapsed remnant of a massive star when it dies. The weight of the star is supported by repulsion between neutrons, hence it is called a neutron star.

Answer 8

Neutron stars, also known as pulsars, are made out of, well neutrons.
Nothing but neutrons, wall-to-wall neutrons so to speak. Normal atoms are mostly empty space. It takes 100,000 protons to span diameter of one hydrogen atom. The only thing in all that 3-dimensional space is a single proton. Neutron stars have no atoms because the tremendous gravity squeezes all the empty space out of all the atoms. Atoms are crushed out of existence, their electrons are pushed into protons making neutrons. A cubic centimeter of neutron star material weighs 1,000's of tons!
The crab nebula has a pulsar or neutron star at its center, it is perhaps the most well know neutron star example. It it the remains of a supernova that exploded in 1054 ad.

Answer 9

Atoms so dense that the electrons have been lost and all thats left is the neutrons and protons so compact that its basically just neutrons.

Answer 10

I don't think the neutrons come from combining electrons and protons; it's just that all the electrons and protons are blasted away in supernova explosion, leaving nothing but neutrons.
