Photometric Distances for Metal-poor Giants and a Search for Hypervelocity Stars with LAMOST DR13 and Gaia DR3
Shuai Xu, Haibo Yuan, Bowen Huang +2
Hypervelocity stars (HVSs) are stars with velocities high enough to escape the Milky Way, but their identification depends sensitively on distance estimates, particularly for dista…

Using Lithium and Beryllium to Study Structure and Evolution of Rotating Stars: Spite Plateau of Halo Stars
Wuming Yang, Shuya Dou, Xiangcun Meng +2
The observed lithum (Li) abundance of Galactic halo stars mainly fall within the range of 2.0--2.4 dex. This nearly constant value, known as the Spite plateau, is approximately a f…

Using Lithium and Beryllium to Study Structure and Evolution of Rotating Stars
Wuming Yang, Haibo Yuan, Yaqian Wu +2
The chemical composition of the Sun is still a highly controversial issue. No solar model has yet been able to simultaneously reproduce the solar lithium and beryllium abundances,…
