Neutron star. Cutaway artwork of the internal structure of a neutron star. A neutron star is the remains of a massive star that has collapsed under its own gravity after its nuclear reactions ceased. It is as dense as an atomic nucleus,having a mass of up to three times that of the Sun despite being only around 10 kilometres across. A quantum mechanical effect (degeneracy) prevents further collapse. The photosphere (blue) conceals crusts (red) of electrons and atomic nuclei. Free neutrons form a superfluid (pink). The solid core (yellow) exceeds nuclear densities. The lines represent the magnetic field,such as found in radio pulsars (rotating magnetised neutron stars) | |
