On the Formation of the Double Neutron Star Binary PSR J1846-0513

Long Jiang, Kun Xu, Shuai Zha +5

The double neutron star PSR J1846-0513 is discovered by the Five-hundred-meter Aperture Spherical radio Telescope (FAST) in Commensal Radio Astronomy FAST Survey. The pulsar is rev…

Ultraluminous X-ray sources with He star companions

Luhan Li, Bo Wang, Dongdong Liu +3

Ultraluminous X-ray sources (ULXs) are non-nuclear point-like objects observed with extremely high X-ray luminosity that exceeds the Eddington limit of a black hol…

On the Interacting/Active Lifetime of Supernova Fallback Disk around Isolated Neutron Stars

Kun Xu, Hao-Ran Yang, Long Jiang +3

The fallback disk model is widely accepted to explain long-period neutron stars (NSs) which can't be simulated by magnetic dipole radiation. However, no confirmed detection of disk…

Formation of PSR J1012+5307 with an extremely low-mass white dwarf: testing magnetic braking models

Na Wei, Kun Xu, Zhi-Fu Gao +2

PSR J1012+5307 is a millisecond pulsar with an extremely low-mass (ELM) white dwarf (WD) companion in an orbit of 14.5 hours. Magnetic braking (MB) plays an important role in influ…

Electron-capture supernovae in NS+He star systems and the double neutron star systems

Yun-Lang Guo, Bo Wang, Wen-Cong Chen +4

Electron-capture supernovae (EC-SNe) provide an alternative channel for producing neutron stars (NSs). They play an important role in the formation of double NS (DNS) systems and t…
