Chemical abundances of 20 barium stars from the OHP spectra
Guochao Yang, Jingkun Zhao, Yanchun Liang +7
Based on the high resolution and high signal-to-noise spectra, we derived the chemical abundances of 20 elements for 20 barium (Ba-) stars. For the first time, the detailed abundan…
Overview of the LAMOST survey in the first decade
Hongliang Yan, Haining Li, Song Wang +24
The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), also known as the Guoshoujing Telescope, is a major national scientific facility for astronomical research l…
A Catalogue of OB Stars from LAMOST Spectroscopic Survey
Zhicun Liu, Wenyuan Cui, Chao Liu +3
We present 22\,901 OB spectra of 16\,032 stars identified from LAMOST DR5 dataset. A larger sample of OB candidates are firstly selected from the distributions in the spectral line…
The odd-isotope fractions of Barium in the strongly r-process enhanced (r-II) stars
Wenyuan Cui, Xiaohua Jiang, Jianrong Shi +2
We determined the \fodd\ values, , , , , which correspond to the r-contribution 100\% for four r-II stars, \cs, \hen, \hes\, and…
Three new barium dwarfs with WD companions: BD+68 1027, RE J0702+129 and BD+80 670
X. M. Kong, Y. Bharat Kumar, G. Zhao +6
We report three new barium (Ba) dwarfs lying in Sirius-like systems, which provides direct evidence that Ba dwarfs are companions to white dwarfs (WDs). Atmospheric parameters, ste…
Chemical abundance analysis of 19 barium stars
G. C. Yang, Y. C. Liang, M. Spite +10
We aim at deriving accurate atmospheric parameters and chemical abundances of 19 barium (Ba) stars, including both strong and mild Ba stars, based on the high signal-to-noise ratio…
