WebNeutron stars form in the death throes of stars with masses of 10–20 M ⊙. Such high-mass stars can form at any time. Theory suggests, though, that they are dominant in the early … Any main-sequence star with an initial mass of above 8 times the mass of the sun (8 M☉) has the potential to produce a neutron star. As the star evolves away from the main sequence, subsequent nuclear burning produces an iron-rich core. When all nuclear fuel in the core has been exhausted, the core must be supported by degeneracy pressure alone. Further deposits of mass from shell …
