Let us consider a 1.4 solar mass neutron star, which, if not spinning would have a radius of about 10km. Ignoring relativistic corrections (which will be significant) the angular velocity $\omega$ of a circular orbit just above that surface is given by $$r\omega^2 = GM/r^2$$ so $$\omega = \sqrt{\frac{GM}{r^3}}$$ and putting in values, we find \$\omega = 13.6 ...
