NLTE Analysis of Copper Abundances in the Galactic Bulge Stars
X. D. Xu, J. R. Shi, H. L Yan
Based on the medium-high resolution (R~ 20,000), modest signal-to-noise ratio (S/N > 70) FLAMES-GIRAFFE spectra, we investigated the copper abundances of 129 red giant branch stars…

NLTE analysis of copper lines in different stellar populations
J. R. Shi, H. L. Yan, Z. M. Zhou +1
The copper abundances of 29 metal-poor stars are determined based on the high resolution, high signal-to-noise ratio spectra from the UVES spectragraph at the ESO VLT telescope. Ou…

Super lithium-rich K giant with low to ratio
Y. T. Zhou, J. R. Shi, H. L. Yan +5
The lithium abundances in a few percent of giants exceed the value predicted by the standard stellar evolution models, and the mechanisms of Li enhancement are still under debate.…
