The spin-up of low-magnetic neutron stars by the accretion of matter onto the star is investigated. Calculations have been made for the evolution of the rotation of a neutron star and applied to different stellar models. It is shown that the existence of a millisecond pulsar imposes no restriction on any of the equations of state considered. However, constraints would arise with the possible discovery of 'third-octave pulsars' (with frequencies in excess of 1000 Hz). Predictions are made as to the distribution of bursters over the orbital periods of neutron stars (about half of these having similar orbital periods). It is demonstrated that in the case of continued accretion onto a star (after it has acquired the critical angular frequency allowing no deviation from axial symmetry), specific accretion disks can be formed with a smooth transition into a star. The specific angular momentum is computed for a neutron star at the instant of the attainment of the Oppenheimer-Volkoff limit.
