Chemical Abundances and Globular Clusters of Milky Way Dwarf Galaxies
Baitian Tang, Shihui Lin, Ruoyun Huang +5
We present an overview of our ongoing GASTRONOMI project, which investigates the coevolution of the Milky Way (MW), its satellite dwarf galaxies, and their star clusters through ch…
Binary Constraints on the Origin of Nitrogen-rich Field Stars
Liao Yang, Baitian Tang, José G. Fernández-Trincado +5
Recent JWST observations have revealed galaxies with unusually high N/O ratios, suggesting that nitrogen enrichment may be common in intense star-forming environments in the early…
Multiple populations detection with the Chinese Space Station Survey Telescope main survey camera
Zhuohang Li, Xia Li, Hao Tian +6
Multiple stellar populations (MPs), characterized by star-to-star light-element abundance variations, are ubiquitous in globular clusters (GCs). Spectroscopy directly reveals these…
APOGEE chemical abundances of stars in the MW satellites Fornax, Sextans, Draco and Carina
Cheng Xu, Yi Qiao, Baitian Tang +3
During its evolution, the Milky Way (MW) incorporated numerous dwarf galaxies, particularly low-mass systems. The surviving dwarf galaxies orbiting the MW serve as exceptional labo…
Spatial Property of Multiple Metallic Populations in the Tidal Stream of Ï Centauri
Shiru Zheng, Baitian Tang, Long Wang +4
Ï Centauri, the remnant nucleus of an accreted dwarf galaxy, is a unique laboratory for studying complex stellar populations. The recently discovered Fimbulthul stream provides a…
A Tale of Two Origins: In-Situ versus Accreted Nitrogen-Rich Field Stars in the MW
Yi Qiao, Baitian Tang, José G. Fernández-Trincado +14
Spectroscopic surveys have identified significant numbers of metal-poor nitrogen-rich (N-rich) field stars. These stars are strong candidates for escapees from globular clusters (G…
