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…

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 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 …

Radial velocity variability fractions of different types of hot subdwarf stars

Ruijie He, Xiangcun Meng, Zhenxin Lei +2

Different types of hot subdwarfs may have different origins, which will cause them to present different radial velocity (RV) variability properties. Only 64% of our single-lin…

Variable white dwarfs in TMTS: Asteroseismological analysis of a ZZ Ceti star, TMTS J17184064+2524314

Jincheng Guo, Yanhui Chen, Yonghui Yang +24

The Tsinghua University-Ma Huateng Telescope for Survey (TMTS) has been constantly monitoring the northern sky since 2020 in search of rapidly variable stars. To find variable whit…

Hot subdwarf stars identified in LAMOST DR8 with single-lined and composite spectra

Zhenxin Lei, Ruijie He, Peter Nemeth +6

222 hot subdwarf stars were identified with LAMOST DR8 spectra, among which 131 stars show composite spectra and have been decomposed, while 91 stars present single-lined spectra.…
