WE have already1 distinguished between three types of pulsars depending upon their mode of formation. Here we discuss some implications of this classification scheme. We suggest the nomenclature types L, S and D for the three types of pulsars. Type S (S for single) consists of pulsars formed as a result of supernova explosions of single stars. Types D and L refer to pulsars which come from massive close binary systems. Pulsars produced by supernova explosions in and leading to the disruption of the binaries belong to type D (D for disrupted), while the old, rejuvenated neutron stars liberated from binaries by the supernova explosions of the companion stars constitute type L (L for liberated). Type D consists of two subsets; a pulsar belongs to type D1 if its formation, accompanied by the disruption of the binary, is a result of the supernova explosion of the first (originally the more massive) star; to type D2, if a result of the supernova explosion of the second (originally the less massive) star. Thus type D1 pulsars are associated with OB runaways, while type D2 pulsars are associated with type L pulsars.
