Abstract. The observation and study of maximally-rotating neutron stars, close to mass-shedding limit, may be the key to understand the dense nuclear matter. While the theoretical predictions allow them to rotate extremely fast, the fastest observed one has a frequency of only 716 Hz. However, the theoretical study of maximally-rotating neutron stars bulk properties, along with future observations, will lead to useful insight at supra-nuclear densities and even more, to strong constraints on the nuclear equation of state. Furthermore, the time evolution of a neutron star may be an effective indicator of its final fate.
