Ultra-compact X-ray Binaries: A Review
Bo Wang, Dongdong Liu, Yunlang Guo +3
Ultra-compact X-ray binaries (UCXBs) are a subclass of low-mass X-ray binaries (LMXBs) characterized by ultra-short orbital periods, typically less than min. They consist…

Xing-Peng Yang, Kun Xu, Zhi-Fu Gao +2
In the bulge of M31, the Chandra observations discovered a possible black hole (BH) ultracompact X-ray binary (UCXB) Seq.1 with an orbital period of 7.7 minutes and a maximum X-ray…
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…
