WebNeutron stars are stellar remnants that pack more mass than the Sun into a sphere about as wide as New York City’s Manhattan Island is long. A neutron star forms when a main sequence star with between about eight and 20 times the Sun’s mass runs out of hydrogen in its core. 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 shel… csd inlog
