Eclipsing Millisecond Pulsars with He Star Companions

Yunlang Guo, Bo Wang, Xiangdong Li, Dongdong Liu et al. • The Astrophysical Journal (2025)

Eclipsing millisecond pulsars (MSPs) are a type of pulsar binaries with close orbits (≲1.0 day). They are important objects for studying the accretion history of neutron stars (NSs), pulsar winds, and the origin of isolated MSPs, etc. Recen...
