The Universal Stellar Mass-Stellar Metallicity Relation for Dwarf Galaxies
Evan N. Kirby, Judith G. Cohen, Puragra Guhathakurta +3
We present spectroscopic metallicities of individual stars in seven gas-rich dwarf irregular galaxies (dIrrs), and we show that dIrrs obey the same mass-metallicity relation as the…
Normal and Outlying Populations of the Milky Way Stellar Halo at [Fe/H] < -2
Judith Cohen, Norbert Christlieb, Ian Thompson +5
From detailed abundance analysis of >100 Hamburg/ESO candidate extremely metal-poor (EMP) stars we find 45 with [Fe/H] < -3.0 dex. We identify a heretofore unidentified group: Ca-d…
Measuring Detailed Chemical Abundances From Co-added Medium Resolution Spectra I. Tests using Milky Way dwarf spheroidal galaxies and globular clusters
Lei Yang, Evan N. Kirby, Puragra Guhathakurta +2
The ability to measure metallicities and α-element abundances in individual red giant branch (RGB) stars using medium-resolution spectra () is a valuable tool for d…
