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…
Variability of magnetic hot stars from the TESS observations
Dong-Xiang Shen, Gang Li, Iskandar Abdusamatjan +7
Magnetic hot stars refer to the stars, which effective temperatures approximately in the range from 7,000 to 50,000 K, and with large-scale globally organized magnetic fields. Thes…
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…
Photometric properties and stellar parameters of the rapidly rotating magnetic early-B star HD 345439
Dong-Xiang Shen, Jin-Zhong Liu, Chun-Hua Zhu +8
We first present the multicolor photometry results of the rapidly rotating magnetic star HD 345439 using the Nanshan One-meter Wide-field Telescope. From the photometric observatio…
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…
Post-merger evolution of double helium white dwarfs and distribution of helium-rich hot subdwarfs
Jinlong Yu, Xianfei Zhang, Guoliang Lv
The mergers of double helium white dwarfs are believed to form isolated helium-rich hot subdwarfs. Observation shows that the helium-rich hot subdwarfs can be divided into two subg…
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…
