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 +5
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…
