报告摘要：

Among the binary millisecond pulsar populations, there is a group of millisecond pulsars with ultralight companions (referred to as spider pulsars) or extremely low mass (ELM) He white dwarfs (WDs). These systems with WD companions, are the progenitors of ultra-compact X-ray binaries that serve as important gravitational wave sources. However, the formation and evolution of these systems are not well understood. In this talk, I will talk about the binary formation model of spider pulsars and the discovery of the spider pulsar M71E with FAST. Subsequently, I will talk about the formation and evolution of binary millisecond pulsars with ELM WDs, along with a discussion of the properties of these systems as gravitational wave sources.
