The Origins of Neutron-capture Elements In Globular Cluster M22
Muhammad Zeshan Ashraf, Wenyuan Cui, Hongjie Li
The chemical abundances of metal-poor stars in globular clusters provide important constraints on their evolutionary scenarios. Using both main r-process and weak r-process pattern…
The Abundance Origin Of A Highly r-process-Enhanced r-II Star: LAMOST J020623.21+494127.9
Muhammad Zeshan Ashraf, Wenyuan Cui, Hongjie Li
Object LAMOST J020623.21+494127.9 (program star) in the thin disk of the Milky Way (MW) is reported as a highly r-process-enhanced (RPE) r-II star with[Eu/Fe]= +1.32 and [Fe/H]= -0…
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…
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…
Estimating R-Process Yields from Abundances of the Metal-Poor Stars
Hongjie Li, Wenjuan Ma, Wenyuan Cui +1
The chemical abundances of metal-poor stars provide important clues to explore stellar formation history and set significant constraints on models of the r-process. In this work, w…
Investigation of the Puzzling Abundance Pattern in the Stars of the Fornax Dwarf Spheroidal Galaxy
Hongjie Li, Wenyuan Cui, Bo Zhang
Many works have found unusual characteristics of elemental abundances in nearby dwarf galaxies. This implies that there is a key factor of galactic evolution that is different from…
Study of Neutron-Capture Element Abundances in Metal-Poor Stars
Hongjie Li, Xiaojing Shen, Shuai Liang +2
This work describes a study of elemental abundances for 30 metal-poor stars whose chemical abundances provide excellent information for setting constraints on models of neutron-cap…
Study of The Abundance Patterns in The Metal-Poor Stellar Stream
Hongjie Li, Shuai Liang, Wenyuan Cui +1
The chemical abundances of the metal-poor stars in the stellar stream provide important information for setting constraints on models of neutron-capture processes. The study of the…
