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…
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…
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…
Fates of the sub-stellar objects (FOSSO) I. Fates of the known brown dwarfs in main-sequence--BD binaries
Zhangliang Chen, Hongming Jin, Hongwei Ge +4
Context. Understanding the survival and orbital evolution of brown dwarf (BD) companions during the post-main-sequence (MS) evolution of their host stars is increasingly important,…
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…
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 …
