Evidence of Supernova Between Formation of Stellar Populations in a Globular Cluster
Evan N. Kirby, Roman Gerasimov, Alice Cai +3
Globular clusters do not undergo conventional chemical evolution driven by supernova enrichment. Instead, they exhibit unique abundance patterns of the light elements, which cannot…

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…

-process Abundance Dispersion in the Globular Cluster M5 using Keck Archival Data
Pranav Nalamwar, Evan N. Kirby, Alice Cai
We studied RGB stars in the mildly metal-rich globular cluster M5 ([Fe/H] ) using archival high-resolution spectra from the Keck Observatory archive (KOA) to better u…
