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…
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…
The influence of rotation and metallicity on the explodability of massive stars
Renyu Luo, Chunhua Zhu, Guoliang Lü +4
During the late stages of massive stellar evolution, failed supernovae (FSN) may form through core-collapse processes. The traditional evaluation criterion 0.45, pri…
The mixing of internal gravity waves and lithium production in intermediate-mass AGB stars
Zhijun Wang, Guoliang Lü, Chunhua Zhu +3
Context: Intermediate-mass asymptotic giant branch (AGB) stars influence Galactic lithium evolution by ejecting surface material (including Li) via stellar winds. Internal gravity…
