A Low-mass Model of The Milky Way: The Disk Warp Resulting from A Galaxy Merger
Mingji Deng, Cuihua Du, Jian Zhang +2
Previous studies have shown that disk warps can result from galaxy mergers. Recent research indicates a noticeable decline in the rotation curve (RC) of the Milky Way (MW), suggest…
Kinematic, Elemental and Structural Dependences on Metallicity in the Galactic Bulge
Haoyang Liu, Cuihua Du, Zhongcheng Li +2
We selected Bulge stars from APOGEE DR17 cross-matched with astrometric data from \textit{Gaia} DR3. Bulge stars were divided into sub-samples with line-of-sight velocity dispersio…
CNN-Derived Elemental Abundances of LAMOST DR10 Giants: Implications for Galactic Substructures
Haoyang Liu, Cuihua Du, Mingji Deng +1
Stellar parameters and abundances provide crucial insights into stellar and Galactic evolution studies. In this work, we developed a convolutional neural network (CNN) to estimate…
Systematic search for blue hyper-velocity stars from LAMOST survey
Yongkang Sun, Yang Huang, Jifeng Liu +6
Hypervelocity stars (HVSs) represent a unique class of objects capable of escaping the gravitational pull of the Milky Way due to extreme acceleration events, such as close encount…
Investigate Substructures of the Inner Halo Using the StarGO Algorithm with APOGEE DR17
Zhongcheng Li, Cuihua Du, Haoyang Liu +1
We applied Stars' Galactic Origin (StarGO) algorithm in 7D space (i.e., [Fe/H], [Mg/Fe], [Al/Fe], , , , ) to analyze stars in the inner halo with APOGEE DR1…
Chemical Components in the Virgo Overdensity and Hercules-Aquila Cloud: hints of more than one merger event in GSE-like debris
Haoyang Liu, Cuihua Du, Thomas Donlon +1
Using elemental abundances for 1.26 million K giants in the LAMOST DR8 value-added catalog, we analyze the chemical abundances of the Virgo Overdensity (VOD) and Hercules-Aquila Cl…
