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 +4
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…
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…
Where do they come from? Identification of globular cluster escaped stars
Cheng Xu, Baitian Tang, Chengyuan Li +5
Globular clusters (GCs), as old as our Galaxy, constantly lose their members to the field as they cross through the Milky Way (MW). These GC escaped stars (or escapees) are suggest…
Driving factors behind multiple populations
Ruoyun Huang, Baitian Tang, Chengyuan Li +9
Star clusters were historically considered simple stellar populations, with all stars sharing the same age and initial chemical composition. However, the presence of chemical anoma…
Chemo-dynamical Nature of the Anticenter Stream and Monoceros Ring
Yi Qiao, Baitian Tang, Jianhui Lian +2
In the epoch of deep photometric surveys, a large number of substructures, e.g., over-densities, streams, were identified. With the help of astrometry and spectroscopy, the communi…
On the identification of N-rich metal-poor field stars with future China space station telescope
Jiajun Zhang, Baitian Tang, Jiang Chang +6
During the long term evolution of globular clusters (GCs), a part of member stars are lost to the field. The recently found nitrogen-rich (N-rich) metal-poor field stars are promis…
The influence of black holes on the binary population of the globular cluster Palomar 5
Long Wang, Mark Gieles, Holger Baumgardt +3
The discovery of stellar-mass black holes (BHs) in globular clusters (GCs) raises the possibility of long-term retention of BHs within GCs. These BHs influence various astrophysica…
Searching for multiple populations in star clusters using the China Space Station Telescope
Chengyuan Li, Zhenya Zheng, Xiaodong Li +6
Multiple stellar populations (MPs) in most star clusters older than 2 Gyr, as seen by lots of spectroscopic and photometric studies, have led to a significant challenge to the trad…
