A Possible Triple Formation Scenario of Binary Black Hole Merge With One In Pair-instability Supernova Mass Gap
Tian Huang, Xizhen Lu, Guoliang Lü +8
Observations of binary black hole (BBH) mergers detected by LIGO -- such as GW170729, GW190620, GW190706, GW230107, GW230820, and GW230928 -- feature high effective spins and prima…
Mass distribution of neutron stars in binary systems
Zhe Hu, GuoLiang Lv, ChunHua Zhu +5
It is known that the mass distribution of the known neutron stars (NSs) exhibits a bimodal pattern. The origin of this distribution remains a subject of debate. We constructed a su…
A low mass and radius neutron star candidate in XTE J1810-189?
Shoutao Ban, Helei Liu, Zhaosheng Li +7
Photosphere radius expansion (PRE) bursts provide a crucial tool for constraining the mass and radius of neutron stars. In this study, we analyze time-resolved spectroscopic data f…
Mass-Radius Constraints for 2S 0918-549 from an RXTE Superexpansion Burst: A Direct Cooling-Tail Analysis
Hongbin Fan, Helei Liu, Zhaosheng Li +6
Thermonuclear (Type I ) X-ray bursts from accreting neutron stars offer a means to determine neutron-star (NS) mass () and radius () and thereby probe the properties of matte…
Evolution of cataclysmic variables under different magnetic braking prescriptions
Bingyao Zhou, Chunhua Zhu, Guoliang Lü +3
Context. The evolution of cataclysmic variables (CVs) - interacting binaries where a low-mass donor transfers matter to a white dwarf via an accretion disk - is critically controll…
Formation of the Dormant Black Holes with Luminous Companions from Binary or Triple Systems
Zhuowen Li, Xizhen Lu, Guoliang Lü +6
Recently, a class of dormant black hole binaries with luminous companions (dBH-LC) has been observed, such as BH1, BH2, and BH3. Unlike previously discovered X-ray BH binari…
