Fast-rotating A- and F-type stars with Hα emissions in NGC 3532, candidate UV-dim stars?
Chenyu He, Chengyuan Li, Gang Li
Extended main-sequence stars that are dim in the ultraviolet passbands of Hubble Space Telescope (UV-dim stars) are found in several young and intermediate-age Magellanic Cloud sta…
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…
On the roles of stellar rotation and binarity in NGC 2423's main-sequence turnoff region
Yutian Bu, Chenyu He, Li Wang +2
Research has shown that many young and intermediate-age clusters (younger than 2 Gyr) have extended main sequences and main-sequence turnoffs (eMSTOs), which cannot be adequa…
The Origin of Young Stellar Populations in NGC 1783: Accretion of External Stars
Li Wang, Licai Deng, Xiaoying Pang +4
The presence of young stellar populations in the Large Magellanic Cloud cluster NGC 1783 has caught significant attention, with suggestions ranging from it being a genuine secondar…
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…
The Stellar "Snake" -- II: The Mass Function
Xiang-Ming Yang, Sarah A. Bird, Jiadong Li +8
We present a comprehensive investigation on the mass function (MF) of a snake-like stellar structure in the solar neighbourhood, building on our previous discovery. To ensure the r…
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…
Extended Main Sequences in Star Clusters
Chengyuan Li, Antonino P. Milone, Weijia Sun +1
Extended main sequences (eMSs) and extended main-sequence turnoffs (eMSTOs) are fascinating phenomena that are routinely observed in star clusters. These phenomena strongly challen…
