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…

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…

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…

A new code for low-resolution spectral identification of white dwarf binary candidates

Genghao Liu, Baitian Tang, Liangliang Ren +7

Close white dwarf binaries (CWDBs) are considered to be progenitors of several exotic astronomical phenomena (e.g., type Ia supernovae, cataclysmic variables). These violent events…

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…

The role of tidal interactions in the formation of slowly rotating early-type stars in young star clusters

Chenyu He, Chengyuan Li, Weijia Sun +9

The split main sequences found in the colour-magnitude diagrams of star clusters younger than ~600 Myr are suggested to be caused by the dichotomy of stellar rotation rates of uppe…

Multiple stellar populations at less evolved stages-III: a possible helium spread in NGC 2210

Chengyuan Li, Xin Ji, Long Wang +6

Helium variations are common features of globular clusters (GCs) with multiple stellar populations. All the formation scenarios predict that secondary population stars are enhanced…

A Systematic Search for Short-period Close White Dwarf Binary Candidates Based on Gaia EDR3 Catalog and Zwicky Transient Facility Data

Liangliang Ren, Chengyuan Li, Bo Ma +4

Galactic short-period close white dwarf binaries (CWDBs) are important objects for space-borne gravitational-wave (GW) detectors in the millihertz frequency bands. Due to the intri…

The role of binarity and stellar rotation in the split main sequence of NGC 2422

Chenyu He, Weijia Sun, Chengyuan Li +8

In addition to the extended main-sequence turnoffs widely found in young and intermediate-age (~ 600 Myr-2 Gyr-old) star clusters, some younger clusters even exhibit split main seq…

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…
