Could a neutron star be active, fusioning neutrons into something more dense and releasing constant power?
Could a neutron star be a bit like our Sun or any other star?
Just to have a different scale:
A neutron star fusioning not hydrogen and other elements but neutrons and quarks in its core at a stable, constant speed, would release energy, and the…

Are there any known neutron stars just below the Tolman–Oppenheimer–Volkoff limit?
Do we know any neutron stars just below the Tolman–Oppenheimer–Volkoff limit?
And how are they different from most other neutron stars?

Can we apply no hair theorem to neutron stars?
As neutron stars are composed of neutrons only and we can't know where the neutron comes from (eg: from what atoms), does neutron stars also fulfill no hair theorem?

Did cosmological natural selection get a reprieve?
The March 2014 issue of Physics Today has an article by Lee Smolin in which he argues that natural laws must change over time. As examples of such theories, he gives Penrose's CCC and his own cosmological natural selection…

Artificial degenerate matter (by "non-explodey" methods) -- physically plausible?
White dwarf matter, neutron-degenerate matter (I'm still confused as to whether this is the same thing as "neutronium" or not), and other possible types of degenerate matter like quark stars are generally discussed in the context of stars, that have…

Protons and neutrons inside neutron stars?
Are there any amount of protons, electrons and other subatomic particles inside neutron stars?
I wonder if there are protons or electrons inside neutron stars trapped by their gravity and degeneracy pressure...How many electrons/protons are there if…

Is a neutron star a classical system or a quantum one?
If we consider the perspective that the neutron star is just a very large atom, then theoretically (disregarding that the smallest possible neutron star is kilometers in diameter) from the hydrogen atom to the neutron star, there'd be a continuous…
