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…

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 Highly Magnetic Ultra Massive White Dwarf with a 23-minute Rotation Period
Jincheng Guo, Xiaofeng Wang, Qichun Liu +17
We present a physical characterization of TMTS J00063798+3104160 (J0006), a rapidly rotating,ultra-massive white dwarf (WD) identified in high-cadence light curves from the Tsinghu…
