Untangling the Sources of Abundance Dispersion in Low-Metallicity Stars

Emily J. Griffith, Jennifer A. Johnson, David H. Weinberg +4

We measure abundances of 12 elements (Na, Mg, Si, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni) in a sample of 86 metal-poor ($-2\lesssim \text{[Fe/H]}\lesssim -1$) subgiant stars in the so…
