The Binary Fraction of Stars in Dwarf Galaxies: the Cases of Draco and Ursa Minor
Meghin Spencer, Mario Mateo, Edward Olszewski +3
Measuring the frequency of binary stars in dwarf spheroidal galaxies (dSphs) requires data taken over long time intervals. We combine radial velocity measurements from five literat…
Elemental Abundances in M31: Alpha and Iron Element Abundances from Low-Resolution Resolved Stellar Spectroscopy in the Stellar Halo
Ivanna Escala, Evan N. Kirby, Karoline M. Gilbert +2
Measurements of [Fe/H] and [/Fe] can probe the minor merging history of a galaxy, providing a direct way to test the hierarchical assembly paradigm. While measurements of [/F…
Neutron Star Mergers Are the Dominant Source of the r-process in the Early Evolution of Dwarf Galaxies
Gina E. Duggan, Evan N. Kirby, Serge M. Andrievsky +1
There are many candidate sites of the r-process: core-collapse supernovae (including rare magnetorotational core-collapse supernovae), neutron star mergers, and neutron star/black…
HALO7D I: The Line of Sight Velocities of Distant Main Sequence Stars in the Milky Way Halo
Emily C. Cunningham, Alis J. Deason, Constance M. Rockosi +5
The Halo Assembly in Lambda-CDM: Observations in 7 Dimensions (HALO7D) dataset consists of Keck II/DEIMOS spectroscopy and Hubble Space Telescope-measured proper motions of Milky W…
Evolution of the Stellar Mass--Metallicity Relation - I: Galaxies in the z~0.4 Cluster Cl0024
Nicha Leethochawalit, Evan N. Kirby, Sean M. Moran +2
We present the stellar mass-stellar metallicity relationship (MZR) in the Cl0024+1654 galaxy cluster at z~0.4 using full spectrum stellar population synthesis modeling of individua…
