(Carroll and Ostlie, 16.16) (a) Determine the minimum rotation period for a 1.4 M. neutron star (the fastest it can spin without the centrifugal force being stronger than the gravitational force at the surface). Assume that the radius of the star is 10 km. (b) Use Newton’s expression for the difference between Polar and Equatorial radii of a rotating object to estimate the flattening of a rotating neutron star (of course, it’s a little harder in GR). The expression is Reg – Rp Rav 5222 R3 4GM
