Academics

A Neutron Star is formed in the aftermath of a Supernova explosion. The star was originally rotating with a period of 20 days and had a mass of 2x10³⁰ kg and radius of 6x10⁸ m. After the explosion the star is found to be rotating with a period of 5x10^-3 s.

a) Determine the radius of the collapsed Neutron Star.

b) Determine the density of the material in the Neutron Star

c) State any simplifying assumptions you may have used in determining the above.
