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…

Mining double-line spectroscopic candidates in the LAMOST medium-resolution spectroscopic survey using human-AI hybrid method
Shan-shan Li, Chun-qian Li, Chang-hua Li +5
We utilize a hybrid approach that integrates the traditional cross-correlation function (CCF) and machine learning to detect spectroscopic multi-systems, specifically focusing on d…
