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…
Design, Testing, and Commissioning of the Sun Yat-sen University (SYSU) 80 cm Infrared Telescope
Zhong-Nan Dong, Bin Ma, Chun Chen +23
The Sun Yat-sen University (SYSU) 80 cm telescope is a new generation near-infrared (NIR) facility in China dedicated to time-domain astronomy, while also serving as a testbed for…
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 …
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…
A systematic search for redback and black widow candidates based on the 4FGL-DR3 unassociated sources and the Zwicky Transient Facility data
Chunyan Lu, Liangliang Ren, Jiamao Lin +3
Spider pulsars constitute a distinct subset within the domain of radio millisecond pulsars, divided further into the categories of black widows and redbacks. Evident across multipl…
