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…
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…
Hunting Hidden Axion Signals in Pulsar Dispersion Measurements with Machine Learning
Haihao Shi, Zhenyang Huang, Qiyu Yan +3
In axion models, interactions between axions and electromagnetic waves induce frequency-dependent time delays determined by the axion mass and decay constant. These small delays ar…
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…
