Spatial Property of Multiple Metallic Populations in the Tidal Stream of ω Centauri
Shiru Zheng, Baitian Tang, Long Wang +4
ω 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 f…
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…
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…
Revealing the Origins of Galactic Globular Clusters via Their Mg-Al Abundances
Shihui Lin, Baitian Tang, Genghao Liu +4
Many Galactic globular clusters (GCs) originated in diverse host galaxies before being subsequently incorporated into the Milky Way through hierarchical galaxy assembly. Identifyin…
