Magnetic-field constraints for four magnetic cataclysmic variables from simultaneous continuum and cyclotron modeling
Jiamao Lin, Wenyuan Guo, Yongkang Sun +2
their fields are rarely measured because cyclotron humps must be separated from uncertain continua and assigned to discrete harmonics. We applied a simultaneous continuum-cyclotron…
A Spectroscopic Census of Cluster White Dwarfs from DESI, LAMOST, and SDSS
David R. Miller, Jeremy Heyl, Huahui Yan +2
Gaia has substantially expanded the sample of candidate white dwarfs (WDs) in open clusters, but many remain without spectroscopic characterization. We leverage the increasingly ex…
A Systematic Gaia--ZTF Search for Short-Period Blue Compact-Binary Candidates
Jiamao Lin, Liangliang Ren, Yilong Li +7
We present a catalog of 147 short-period (10.34--106.46~min) blue compact-binary candidates, identified by combining Gaia DR3 astrometry and photometry with ZTF DR23 light curves v…
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…
Escaped White Dwarf Candidates from Open Clusters
Huahui Yan, David R. Miller, Jingkun Zhao +2
Observations reveal a pronounced deficit of white dwarfs (WDs) in open clusters (OCs) relative to theoretical expectations, suggesting that a significant fraction of WDs may have e…
Star Clusters in the Ultraviolet
Annapurni Subramaniam, Samyaday Choudhury, Richard de Grijs +5
Ultraviolet (UV) observations provide a powerful window into the hot and evolved stellar populations that shape the structure, evolution and integrated light of star clusters. Beca…
Testing an Ap-like Magnetic Braking Origin for the Extended Main Sequence in Young Open Clusters
Chengyuan Li
Young open clusters commonly exhibit extended or split upper main sequences, which are widely interpreted as signatures of broad, and in some cases bimodal, stellar rotation distri…
A Candidate Low-mass Disk-eclipsing Binary in the ~316 Myr Open Cluster UPK 13
Jiamao Lin, Yongkang Sun, Chengyuan Li
UPK~13-c2 is a candidate member of the 316~Myr open cluster UPK~13 and was previously classified as a white dwarf + main-sequence (WDMS) binary with 99.44\% confidence. We…
Mass-Orbital Period Distribution of Massive White Dwarfs Formed Through Stable Mass Transfer
Rizhong Zheng, Hongwei Ge, Christopher A Tout +10
White dwarfs (WDs) in binaries can form through either the stable mass-transfer process or common envelope evolution (CEE). Compared to CEE, the stable mass-transfer process can le…
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…
Mock Observations of Multiple Stellar Populations in Tidal Streams of Palomar 5 for the Chinese Space Station Survey Telescope
Xia Li, Long Wang, Chengyuan Li +3
Observations show that multiple stellar populations (MPs) are ubiquitous in globular clusters. The Hubble Space Telescope (HST) has been a pivotal tool for previous photometric stu…
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…
Searching for White Dwarf Candidates Formed Through Binary evolution in Star Clusters
Huahui Yan, Li Wang, David R. Miller +11
White dwarfs (WDs), the evolutionary endpoints of most stars, can form through both single-star and binary channels. While single-star evolutionary models enable reliable WD age es…
MCI: Multi-Channel Imager on the Chinese Space Station Survey Telescope
Zhen-Ya Zheng, Chun Xu, Xiaohua Liu +37
The Multi-Channel Imager (MCI) is a powerful near-ultraviolet (NUV) and visible imager onboard the Chinese Space Station Survey Telescope (CSST). The MCI provides three imaging cha…
A magnetic white dwarf formed through a binary merger within 35 million years
Huahui Yan, Jiamao Lin, Rizhong Zheng +15
White dwarfs (WDs) represent the final evolutionary stage of most stars, typically originating from progenitor stars with masses below approximately 8 to 10 …
Discovery and characterization of ZTF J0112+5827: An 80.9-minute polar with strong cyclotron features
Jiamao Lin, Liangliang Ren, Chengyuan Li +9
We report the discovery and characterization of ZTF J0112+5827, a new magnetic cataclysmic variable with an orbital period of 80.9 minutes. ROSAT observations revealed X-ray emissi…
Multiple stellar populations at less evolved stages. IV. evidence of helium enrichments in four Magellanic globular clusters
Chengyuan Li, Li Wang, Xin Ji +1
Most globular clusters in the local group show multiple stellar populations, a pattern defined by variations of several light elements, with some also displaying dispersions in hea…
Fast-rotating A- and F-type stars with Hα emissions in NGC 3532, candidate UV-dim stars?

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
