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…
A Catalog of 486 Barium Stars Identified in GALAH DR4
Guochao Yang, Jingkun Zhao, Nian Liu +4
We present a catalog of 486 Ba stars identified in the GALAH DR4 survey using high-resolution spectra and precise abundance measurements. The sample was selected based on s-process…
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…
Deep learning-driven atmospheric parameter prediction for hot subdwarf stars with synthetic and observed spectra
Zhenxin Lei, Yangyang Dong, Bokai Kou +4
We design a convolutional neural network (CNN) incorporating channel attention and spatial attention mechanisms to predict atmospheric parameters of hot subdwarfs. The experimental…
