Simultaneous Constraints on the Star Formation History and Nucleosynthesis of Sculptor dSph
Mithi A. C. de los Reyes, Evan N. Kirby, Alexander P. Ji +1
We demonstrate that using up to seven stellar abundance ratios can place observational constraints on the star formation histories (SFHs) of Local Group dSphs, using the Sculptor d…
Star Formation Histories of Ultra-Faint Dwarf Galaxies: environmental differences between Magellanic and non-Magellanic satellites?
Elena Sacchi, Hannah Richstein, Nitya Kallivayalil +18
We present the color-magnitude diagrams and star formation histories (SFHs) of seven ultra-faint dwarf galaxies: Horologium 1, Hydra 2, Phoenix 2, Reticulum 2, Sagittarius 2, Trian…
Stellar kinematics of dwarf galaxies from multi-epoch spectroscopy: application to Triangulum II
Rachel Buttry, Andrew B. Pace, Sergey E. Koposov +9
We present new MMT/Hectochelle spectroscopic measurements for 257 stars observed along the line of sight to the ultra-faint dwarf galaxy Triangulum II. Combining with results from…
Empirical Constraints on Core Collapse Supernova Yields using Very Metal Poor Damped Lyman Alpha Absorbers
Evan Haze Nuñez, Evan N. Kirby, Charles C. Steidel
We place empirical constraints on the yields from zero- and low-metallicity core collapse supernovae (CCSNe) using abundances measured in very metal-poor (VMP; [Fe/H] )…
NGC 147 Corroborates the Break in the Stellar Mass-Stellar Metallicity Relation for Galaxies
Zhuyun Zhuang, Evan N. Kirby, Nicha Leethochawalit +1
The stellar mass-stellar metallicity relation (MZR) is an essential approach to probe the chemical evolution of galaxies. It reflects the balance between galactic feedback and grav…
Elemental Abundances in M31: Gradients in the Giant Stellar Stream
Ivanna Escala, Karoline M. Gilbert, Jennifer Wojno +2
We analyze existing measurements of [Fe/H] and [/Fe] for individual red giant branch (RGB) stars in the Giant Stellar Stream (GSS) of M31 to determine whether spatial abundance…
