Current research intended to understand the issues involved in the link between neutron stars which are observed as pulsars and those which are X-ray sources is considered. Two hypothesis are discussed. The first, called the standard model, suggests that most pulsars originate in supernova explosions starting with moderately high spin rates and strong magnetic fields, both of which gradually decay with time until the pulsar becomes too faint to observe. The second, the accretion induced collapse (AIC) hypothesis, is based on the fact that the precursors of millisecond pulsars are not accreting neutron stars but accreting white dwarfs which undergo AIC, leaving behind a rapidly spinning neutron star which is observed as a millisecond pulsar.
