The Impact of Neutrino Magnetic Moments on the Evolution of the Helium Flash and Lithium-Rich Red Clump Stars
Xizhen Lu, Chunhua Zhu, Guoliang Lü +3
The detection of the neutrino magnetic moment (NMM,) is one of the most significant challenges in physics. The additional energy loss due to NMM can significantly influence th…
The neutrino luminosity and energy spectrum of nova outburst
Hao Wang, Chunhua Zhu, Guoliang Lü +4
The nova outburst can produce a large number of neutrinos, whether it is the nuclear reaction process during the explosion or the shock wave acceleration proton process. We study t…
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)…
Identifying symbiotic stars with machine learning
Yongle Jia, Sufen Guo, Chunhua Zhu +3
Symbiotic stars are interacting binary systems, making them valuable for studying various astronomical phenomena, such as stellar evolution, mass transfer, and accretion processes.…
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…
The effects of rotation, metallicity and magnetic field on the islands of failed supernovae
Lei Li, Chunhua Zhu, Sufen Guo +2
Failed supernovae (FSN) are a possible channel for the formation of heavy stellar-mass black holes ( M). However, the effects of metallicity, rotation and…
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…
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 Distances to Molecular Clouds at High Galactic Latitudes based on GAIA DR2
Qing-Zeng Yan, Bo Zhang, Ye Xu +4
We report the distances of molecular clouds at high Galactic latitudes (|b|>10) derived from parallax and G band extinction (A) measurements in the second Gaia da…
Identifying quasars with astrometric and mid-infrared methods from APOP and ALLWISE
Sufen Guo, Zhaoxiang Qi, Shilong Liao +5
Context. Quasars are spatially stationary, and they are essential objects in astrometry when defining reference frames. However, the census of quasars is far from complete. Mid-inf…
A compilation of known QSOs for the Gaia mission
Shi-long Liao, Zhao-xiang Qi, Su-fen Guo +1
Quasars are essential for astrometric in the sense that they are spatial stationary because of their large distance from the Sun. The European Space Agency (ESA) space astrometric…
The properties of the quasars astrometric solution in Gaia DR2
Shilong Liao, Beatric Bucciarelli, Zhaoxiang Qi +3
Gaia data release 2 (DR2) provides the best non-rotating optical frame aligned with the radio frame (ICRF) thanks to the inclusion of about half-million quasars in the 5-parameter…
