Answer to Question #87222 in Atomic and Nuclear Physics for Samuel

Question

A star ending its life with a mass of twice the mass of the sun is expected to collapse combining its proton and electron to form a neutron star. If a star of mass 2.0× 1.99×1030kg collapsed into the neutron what would be its radius?

Answer 1

When a proton is combined with an electron, the density will increase 0.17*10¹⁵ times, and if the star had a density comparable to that of the sun, after the merger, it will be 0.24*10¹⁷ kg/m³, respectively, the volume will be 17*10¹² m³ and the radius will be 16 km.
