    Why spin angular velocity of a star is greatly enhanced when it collapses under gravitational pull and becomes a neutron star?

    Answer:

                      On collapsing under gravitational pull, size of star decreases. Therefore, its moment of inertia decreases. As angular momentum \[(\text{L}=\text{I}\omega )\] is conserved, and I decreases, therefore, spin angular velocity \[\omega \]  increases.
