Population-Dependent r-process Scatter in the Globular Cluster M15
Lauren E. Henderson, Roman Gerasimov, Evan N. Kirby
Multiple populations, defined by correlations between light element abundances, are an almost ubiquitous property of globular clusters. On the other hand, dispersions among the hea…

Estimating Fe and Mg Abundances in the Milky Way Dwarf Galaxies Using Subaru/HSC and DEIMOS
Jihye Hong, Evan N. Kirby, Tiffany M. Tang +5
We investigate the chemical abundance distributions of the Fornax, Sculptor, Ursa Minor, and Draco dwarf galaxies using Subaru/HSC photometric data. The HSC dataset, which includes…

Neutron-capture Element Abundances of 491 Stars in Milky Way Dwarf Satellite Galaxies from Medium-Resolution Spectra
Lauren E. Henderson, Evan N. Kirby, Mithi A. C. de los Reyes +2
The chemical compositions of evolved stars in Local Group dwarf spheroidal galaxies (dSphs) provide insight into the galaxy's past star formation and nucleosynthesis. Neutron-captu…
