The Milky Way's Early Disk Was Built in Bursts. II. The Multi-component Age-Metallicity Structure of the High- $α$ Disk

Tiancheng Sun, Maosheng Xiang, Jifeng Liu +2

Whether the high- $α$ disk experienced a continuous or episodic star-formation history remains an open question. Here we investigate the age--metallicity distribution of the high-$α…

Testing Chemical Tagging with LAMOST: Intrinsic Abundance Dispersion of Subgiant Stars in the Galactic Disk

Wu Yaqian, Xiang Maosheng, Zhao Gang +4

The scatter in elemental abundances among stars of similar age and metallicity reflects chemical inhomogeneity in their birth environments, making abundance scatter a key observabl…

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…
