Abstract

An understanding of spin frequency evolution of neutron stars in the
low-mass X-ray binary phase is essential to explain the observed spin
distribution of millisecond pulsars, and to probe the stellar and binary
physics, including the possibility of continuous gravitational wave
emission. I will discuss the crucial effects of transient accretion on the
spin evolution of neutron stars. Then, using numerical computations I will
conclude that spin frequency can evolve in two distinctly different modes
in a way which is counter-intuitive. This implies that the traditional way
of spin evolution computation of millisecond pulsars is inadequate in most
cases.
