A possible formation scenario of the Gaia ID 3425577610762832384: inner binary merger inside a triple common envelope
Zhuowen Li, Xizhen Lu, Guoliang Lü +3
Recently, an identified non-interacting black hole (BH) binary, Gaia ID 3425577610762832384 (hereafter G3425), contains a BH (3.6 M) falling within the mass gap and…
A possible formation scenario of the Gaia BH1: inner binary merger in triple systems
Zhuowen Li, Chunhua Zhu, Xizhen Lu +5
Based on astrometric measurements and spectral analysis from DR3, two quiescent black hole (BH) binaries, BH1 and BH2, have been identified. Their origins remain cont…
Novae: An Important Source of Lithium in the Galaxy
Jun Gao, Chunhua Zhu, Guoliang Lü +4
The source of the Galactic Lithium (Li) has long been a puzzle. With the discovery of Li in novae, extensive research has been conducted. However, there still exists a significant…
The population synthesis of Wolf-Rayet stars involving binary merger channels
Zhuowen Li, Chunhua Zhu, Guoliang Lü +5
Wolf-Rayet stars (WRs) are very important massive stars. However, their origin and the observed binary fraction within the entire WR population are still debated. We investigate so…
Evolutionary tracks of massive stars with different rotation and metallicity in neutrino H-R diagram
Hao Wang, Chunhua Zhu, Helei Liu +2
Neutrino losses play a crucial role in the evolution of massive stars. We study the neutrino luminosity of stars ranging from 20 to 90 M_{\odot} from Zero Age Main Sequence (ZAMS)…
An Alternative Formation Scenario for Uranium-rich Giants: Engulfing a Earth-like Planet
Dian Xie, Chunhua Zhu, Sufen Guo +2
The actinides, such as the uranium (U) element, are typically synthesized through the rapid neutron-capture process (r-process), which can occur in core-collapse supernovae or doub…
Hydrogen-free Wolf-Rayet stars: Helium stars with envelope-inflation structure and rotation
Xizhen Lu, Chunhua Zhu, Helei Liu +3
Observations have shown that the effective temperature of hydrogen-free Wolf-Rayet (WR) stars is considerably lower than that of the standard model, which means that the radius of…
Li-rich and super Li-rich giants produced by element diffusion
Jun Gao, Chunhua Zhu, Jinlong Yu +4
Context. About 0.2-2% of giant stars are Li-rich, whose lithium abundance (A(Li)) is higher than 1.5 dex. Among them, near 6% are super Li-rich with A(Li) exceeding 3.2 dex. Meanwh…
Formation, diffusion and accreting pollution of DB white dwarfs
Chunhua Zhu, Helei Liu, Zhaojun Wang +1
Over 1500 DBZ or DZ white dwarfs (WDs) have been observed so far, and polluted atmospheres with metal elements have been found among these WDs. The surface heavy element abundances…
Possible Formation Scenarios of ZTF J153932.16+502738.8-A Gravitational Source Close to the Peak of LISA's Sensitivity
Guoliang Lü, Chunhua Zhu, Zhaojun Wang +4
ZTF J153932.16+502738.8 (ZTFJ1539) is an eclipsing double-white-dwarf system with an orbital period of 6.91 minutes, and is a significant source of LISA detecting gravitational wav…
The Formation of Bimodal Dust Species in Nova Ejecta
Adili Duolikun, Chunhua Zhu, Zhaojun Wang +4
The formation of bimodal dust species (namely the silicate and amorphous carbon dust grains coexistent) in a nova eruption is an open problem. According to the nova model simulated…
The formation of subdwarf A-type stars
Jinlong Yu, Zhenwei Li, Chunhua Zhu +6
Subdwarf A-type stars (sdAs) are objects that have hydrogen-rich spectra with surface gravity similar to that of hot subdwarf stars but effective temperature below the zero-age hor…
The Formation of Bimodal Dust Species in Nova Ejecta I: Chemical Conditions
Chunhua Zhu, Helei Liu, Guoliang Lü +2
The formation of bimodal dust species (that is, both of silicate and amorphous carbon dust grains are observed in a nova eruption) in nova ejecta is still debated. Using the Module…
