We report on observations of six giants in the globular cluster M15 (NGC 7078) using the Subaru Telescope to measure neutron-capture elemental abundances. Our abundance analyses based on high-quality blue spectra confirm the star-to-star scatter in the abundances of heavy neutron-capture elements (e.g., Eu), and no significant s-process contribution to them, as was found in previous studies. We have found, for the first time, that there are anti-correlations between the abundance ratios of…

Iron and neutron-capture element abundance variations in the globular cluster M2 (NGC 7089)
We present CN and CH indices and CaII triplet metallicities for 34 giant stars and chemical abundances for 33 elements in 14 giants in the globular cluster M2. Assuming the program stars are cluster
Heavy Element Abundances in Giant Stars of the Globular Clusters M4 and M5
We present a comprehensive abundance analysis of 27 heavy elements in bright giant stars of the globular clusters M4 and M5 based on high-resolution, high signal-to-noise ratio spectra obtained with
Neutron-capture processes in the early Galaxy
Many observational studies of metal-poor stars that exhibit large excesses of r-process elements have been made in the past decade, and have provided useful constraints on modeling this process.
Primordial r-process Dispersion in Metal-Poor Globular Clusters
Heavy elements, those produced by neutron-capture reactions, have traditionally shown no star-to-star dispersion in all but a handful of metal-poor globular clusters (GCs). Recent detections of low
Rubidium and Lead Abundances in Giant Stars of the Globular Clusters M4 and M5
We present measurements of the neutron-capture elements Rb and Pb for bright giants in the globular clusters M4 and M5. The clusters are of similar metallicity ( -->[Fe/H] − 1.2) , but M4 is
Complete element abundances of nine stars in the r-process galaxy Reticulum II
We present chemical abundances derived from high-resolution Magellan/MIKE spectra of the nine brightest known red giant members of the ultra-faint dwarf galaxy Reticulum II. These stars span the full
Detailed abundances of 15 stars in the metal-poor globular cluster NGC 4833
We have observed 15 red giant stars in the relatively massive, metal-poor globular cluster NGC 4833 using the Magellan Inamori Kyocera Echelle spectrograph at Magellan. We calculate stellar
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 a
Characterizing the Heavy Elements in Globular Cluster M22 and an Empirical s-process Abundance Distribution Derived from the Two Stellar Groups
We present an empirical s-process abundance distribution derived with explicit knowledge of the r-process component in the low-metallicity globular cluster M22. We have obtained high-resolution, high
HEAVY-ELEMENT DISPERSION IN THE METAL-POOR GLOBULAR CLUSTER M92*
Dispersion among the light elements is common in globular clusters (GCs), while dispersion among heavier elements is less common. We present detection of r-process dispersion relative to Fe in 19 red

Neutron-Capture Element Abundances in the Globular Cluster M15.
TLDR
A weighted mean-observed Th/Eu ratio for the stars implies an age for the neutron-capture material in M15 stars of 14+/-3 Gyr, in reasonable agreement with other recent age estimates for Galactic globular clusters.

The heavy elements formed by neutron-capture processes have an interesting history from which we can extract useful clues to and constraints upon both the characteristics of the processes themselves
