Abundances of heavier elements (barium and beyond) in many neutron-capture-element-rich halo stars accurately replicate the solar system r-process pattern. However, abundances of lighter neutron-capture elements in these stars are not consistent with the solar system pattern. These comparisons suggest contributions from two distinct types of r-process synthesis events, a so-called main r-process for the elements above the second r-process peak and a weak r-process for the lighter neutron… Expand
r-Process Enhanced Halo Stars
Abundance observations indicate the presence of rapid-neutron capture (i.e., r-process) elements in old Galactic halo and globular cluster stars. These observations provide insight into the nature ofExpand
Constraints on the Nature of the s- and r-processes
Abstract Neutron-capture (Z > 30) elements are detected in many very metal-poor halo stars, and so they must have been manufactured by some of the earliest element donors in our Galaxy's history. TheExpand
Observational nuclear astrophysics: neutron-capture element abundances in old, metal-poor stars
The chemical abundances of metal-poor stars provide a great deal of information regarding the individual nucleosynthetic processes that created the observed elements and the overall process ofExpand
Study of isotopic fractions and abundances of the neutron-capture elements in HD 175305
The chemical abundances of metal-poor stars are excellent sources of information for setting new constraints on models of Galactic chemical evolution at low metallicities. In this paper we present anExpand
Nucleosynthesis in the early galaxy
Recent observations of r-process-enriched metal-poor star abundances reveal a nonuniform abundance pattern for elements -->Z ≤ 47. Based on noncorrelation trends between elemental abundances as aExpand
The r-process in Metal-poor Stars and Black Hole Formation
Nucleosynthesis of heavy nuclei in metal-poor stars is generally ascribed to the r-process, as the abundance pattern in many such stars agrees with the inferred Solar r-process abundances.Expand

High-resolution abundance analysis of very metal-poor r-I stars

r-Process in Neutron Star Mergers.
TLDR
Sufficient material is ejected to explain the amount of r-process nuclei in the Galaxy by decompression of neutron star material, and the calculated abundances fit the observed solar r-pattern excellently for nuclei that include and are heavier than the A approximately 130 peak. Expand

TLDR
The stellar abundances indicate an increasing contribution from the slow neutron-capture process at higher metallicities in the Galaxy, and the detection of thorium in halo and globular cluster stars offers a promising, independent age-dating technique that can put lower limits on the age of the Galaxy.
