Talk:Neutron star

Jargon needs definitions or links

The terms AP4, MS2, and "(for EOS FPS, UU, APR or L respectively)" are used with no definitions nor links to anything which might explain them. It makes those passages less than helpful.

P.S. to the authors: Thanks for an otherwise nice article. — Preceding unsigned comment added by Oldmeat (talk • contribs) 01:36, 1 March 2017 (UTC)

Unproductive Drive-By Comment

Transient condensates are core properties ranging from Axion matter to various Parton matter to Quark matter to Neutron matter. This Condensate matter makes up over 95% of all matter in the infinite universe. The core does not undergo fusion. It keeps on attracting matter into it. In the case of our Sun its core will photo-disintergrate atoms such as Fe(and all other) to neutrons and protons(change to Neutron) that would become part of the core. The gauge field on the lattice is the resultant property forming a dipolar electromagnetic effect producing vortices, that expel neutrons into the solar envelope that change to protons that than take part in fusion reactions H+H= Helium etc forming all the elements. The Sun's energy is produced by the core 65%, Fusion reactions within the solar envelope 35% and about 5% fission. It all about the core and its properties. Images created by condensates as in the Kilonova hour glass and the release of condensate droplets that produce giant bubbles. — Preceding unsigned comment added by Harry Costas (talk • contribs) 00:20, 2 January 2018 (UTC)

Source of energy?

As we all know, with regular stars, nuclear fusion takes place place in their cores, and this nuclear fusion is what produces the energy emitted thereby.

Neutron stars also produce protons, but I wouldn't guess that nuclear fusion is taking place in their cores.  Would I be wrong to assume it's not?  And, assuming I am correct to guess that there is no nuclear fusion taking place therein, the question then remains: what produces the energy emitted by neutron stars?

If you know the answer to these questions, please help improve this article by adding details about neutron stars' source of energy.

You can ask at the wp:reference desk/Science. Here we must discuss improvements to the article, not the subject. See wp:Talk page guidelines. Cheers and good luck. - DVdm (talk) 15:41, 27 June 2017 (UTC)

Sorry if my purpose was unclear.  (I've now augmented my previous question to make my intentions clearer.)  I was discussing improvements to the article.  By pointing out that there is an interesting aspect of the science behind neutron stars not yet covered in this article, I am giving those with the expertise requisite to improve the article an area upon which to focus their future edits.  Cheers, allixpeeke (talk) 12:08, 30 June 2017 (UTC)

Ok, fair enough. I struck my comment . - DVdm (talk) 12:44, 30 June 2017 (UTC)

Long-term evolution of neutron stars

A short section explaining what the long-term evolution of neutron stars is expected to be would be nice. Can a neutron star cool down to near zero absolute and remain stable against gravitational collapse? Ho wmuch time would the cooling take? (I'd expect this to be orders of magnitude more than the current age of the Universe) Urhixidur (talk) 17:00, 29 September 2017 (UTC)

Weight of the Moon ?

A neutron star is so dense that one teaspoon (5 milliliters) of its material would have a mass over 5.5×1012 kg (that is 1100 tonnes per 1 nanolitre), about 900 times the mass of the Great Pyramid of Giza. In the enormous gravitational field of a neutron star, its weight would be 1.1×1025 N, which is about 15 times the weight of the Moon.[c]

>>> This seems odd to me ? Are we referring to the weight of the moon specifically as if an object of its mass is effected by earth's gravity ?

This part seems to contain an often-quoted error. The Giza pyramid weighs about 6 million tons. A teaspoon of neutron star material weighs about 10 million tons. How could 6 million x 900 = 10 million? — Preceding unsigned comment added by 162.227.178.143 (talk) 23:55, 4 December 2018 (UTC)

But , wouldnt an object of sufficient mass also attract the Earth towards itself with its own gravitational field , thus increasing its relative Weight ? — Preceding unsigned comment added by 2607:FCC8:AB49:2200:B19A:6BCE:F4C3:ABA6 (talk) 22:24, 8 December 2017 (UTC)

Please note that the Moon orbits the Earth. As such, it is the most massive object currently in Earth's gravity - after Theia up and collided with the Earth. --vuo (talk) 13:25, 8 January 2018 (UTC)

Really, this is accepted quality for wikipedia? I expected better188.175.76.2 (talk) 07:24, 16 December 2017 (UTC)

Please feel free to recommend how the article can be improved. --‖ Ebyabe ^talk - General Health ‖ 07:58, 16 December 2017 (UTC)
