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…
Deep Adaptive Optics Imaging Rules Out a Helium Star Companion to PSR J1928+1815
Pranav Nagarajan, Kareem El-Badry, Jim Fuller +2
PSR J1928+1815 is a 10.55 ms millisecond pulsar in a 3.6 hr orbit with a massive (-) companion that produces extended radio eclipses. The companion, proposed t…
The Formation of Electron-capture Supernovae: A Review
Bo Wang, Dongdong Liu, Yunlang Guo +1
It is generally believed that the electron-capture reactions happen when the oxygen-neon (ONe) cores grow in masses close to the Chandrasekhar limit, leading to the formation of ne…
Eclipsing millisecond pulsars with He star companions
Yunlang Guo, Bo Wang, Xiangdong Li +2
Eclipsing millisecond pulsars (MSPs) are a type of pulsar binaries with close orbits (d). They are important objects for studying the accretion history of neutron st…
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…
