【 摘 要 】

This paper investigates the progenitors of Millisecond Pulsars (MSPs) with a distribution of long orbital periods (Porb> 2 d), to show the link between white dwarf (WD) binaries and long orbits for some binary MSPs through the Accretion Induced Collapse (AIC) of a WD. For this purpose, a model is presented to turn binary MSPs into wide binaries and highly circular orbits (e o). The model shows the pulsar systems are relevant to AIC-candidates.
