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…
Astrophysical Origins for the Unusual Chemical Abundance of the Globular Cluster Palomar 1
Ping Niu, Wenyuan Cui, Bo Zhang +1
We study the abundances of α elements, Fe-peak elements, and neutron-capture elements in Pal 1. We found that the abundances of the SNe Ia and main s-process components of Pal 1 ar…
Study of the element abundances in HD 140283: the abundance robustness of the weak r- and main r-process stars
Ping Niu, Wenyuan Cui, Bo Zhang
Many works have attempted to investigate the astrophysical origin of the neutron-capture elements in the metalpoor star HD 140283. However, no definite conclusions have been drawn.…
Is Germanium (Ge, Z=32) A Neutron-Capture Element?
Ping Niu, Weili Liu, Wenyuan Cui +1
Historically,Ge has been considered to be a neutron-capture element. In this case, the r-process abundance of Ge is derived by subtracting the s-process abundance from the total ab…
Possible discovery of the r-process characteristics in the abundances of metal-rich barium stars
W. Y. Cui, B. Zhang, J. R. Shi +3
We study the abundance distributions of a sample of metal-rich barium stars provided by Pereira et al. (2011) to investigate the s- and r-process nucleosynthesis in the metal-rich…
