Carbon in J0815+4729: Casting A Shadow of Doubt on the Interpretation of CH Absorption in the Most Primitive Stars
Junbo Zhang, Carlos Allende Prieto, Yeisson Osorio +7
We revisit the carbon abundance in the primitive iron-poor star J0815+4729 ([Fe/H] 5.49). J0815+4729 is so carbon-enhanced and oxygen-rich that, in addition to CH and C$_{2}…
PhDLspec: physical-prior embedded deep learning method for spectroscopic determination of stellar labels in high-dimensional parameter space
Tianmin Wu, Maosheng Xiang, Jianrong Shi +4
Unlocking the full physical information encoded in low-resolution spectra poses a significant challenge for astronomical survey analysis. Such a task demands modeling spectra and o…
Lithium in Wide Binaries: Effective Temperature Governs Depletion while Rotation Plays a Minor Role
Cheng-Cheng Xie, Hai-Jun Tian, Jian-Rong Shi +1
Using a sample of 116 wide binary systems as coeval and chemically homogeneous stellar pairs, we investigate the factors governing lithium depletion in main-sequence stars. We reco…
Identify ~20,000 Li-rich Giants in the LAMOST Low-Resolution Survey
Ming-Yi Ding, Liang Wang, Jian-Rong Shi +8
Li-rich giants serve as valuable tracers of stellar evolution and surface enrichment processes, for which a statistically large and homogeneous sample is crucial. Using the massive…
Discovery of an Extremely Luminous Type II Cepheid in the Andromeda Giant Stellar Stream: Evidence for a Hierarchical Triple with an Inner Binary Merger
Pinjian Chen, Bingqiu Chen, Xiaodian Chen +7
We report the discovery of LAMOST J0041+3948, the most luminous post-AGB Type II Cepheid (TIIC) known, located in the Andromeda Giant Stellar Stream. Its spectral energy distributi…
Chemical abundances of seven stars in the GD-1 stream
Jing-Kun Zhao, Guang-Wei Li, Wako Aoki +13
We present the first detailed chemical abundances for seven GD-1 stream stars from Subaru/HDS spectroscopy. Atmospheric parameters were derived via color calibrations (…
