Where do the Progenitors of Millisecond Pulsars come from

摘要: Observations of a large population Millisecond Pulsars (MSPs) show wide divergence in the orbital periods (from approximately hours to few months). In standard view, Low-Mass X-Ray Binaries (LMXBs) are considered as progenitors for some MSPs during recycling process. We present systematic study that combines different types compact objects binaries such Cataclysmic Variables (CVs), LMXBs and MSPs. plot them together so called Corbet diagram. Larger samples needed better constrain result function environment formations. A scale diagram showing distribution aspects their relying on Accretion Induced Collapse (AIC) white dwarfs binaries. Thus massive CVs (M >1.1M\odot) can play vital role binary evolution, well physical processes involved formation evolution neutron stars magnetic fields, could turn into with scales periods; this effect be explained by AIC This scenario also suggests fraction isolated Galactic disk formed through same channel, formingthe contribution single-degenerate Type Ia supernova. Furthermore, we have refined statistical using updated data. implies significant studies systems benefit from
