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…
Study of the abundance features of the metal-poor star HD 94028
Wanqiang Han, Lu Zhang, Guochao Yang +2
Recent work has found that the metal-poor star HD 94028 shows interesting abundance features. The s-process material (e.g., Ba, La, Ce, and Pb) and r-process material (e.g., Eu, Os…
Formation of the Abundance Boundaries of the Heavier Neutron-capture Elements in Metal-poor Stars
Guochao Yang, Hongjie Li, Nian Liu +5
The abundance scatter of heavier r-process elements (Z > 56) relative to Fe ([r/Fe]) in metal-poor stars preserves excellent information of the star formation history and provides…
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…
Footprints of the weak s-process in the carbon-enhanced metal-poor star ET0097
Guochao Yang, Hongjie Li, Nian Liu +3
Historically, the weak s-process contribution to metal-poor stars is thought to be extremely small, due to the effect of the secondary-like nature of the neutron source 22Ne(a;n)25…
The odd-isotope fractions of Barium in CEMP-r/s star HE 0338-3945 and r-II star CS 31082-001
Xiaoying Meng, Wenyuan Cui, Jianrong Shi +4
We report the first measurement of the odd-isotope fractions for barium, \fodd\, in two extremely metal-poor stars: a CEMP-r/s star \he\ (\feh\,) and an r-II star \c…
