Question

A neutron star is a star that remains after a supernova, having a large enough density that the it is comprised of mostly neutrons and few protons. A pulsar is a neutron star that spins, radiating electromagnetic energy. We detect this energy as radio waves, noticing that they pulse at a rate of 1 kHz (1000 Hz). Let's assume that this rate corresponds to the rotations per second of the star (1000 rotations per second). Any solid sphere has a moment of inertia equal to (2/5) Qr^2, where Q is the mass and r is the radius. Neutron star masses are constrained to be about twice the mass of the Sun (the Sun's mass is 2 x 10^30 kg), and radii of 12 km. What is the angular momentum of the neutron star? What is the density of the neutron star?
