Untangling the Sources of Abundance Dispersion in Low-metallicity Stars II: Neutron Capture Elements
Emily J. Griffith, Marissa Blum, David H. Weinberg +4
We present the abundances of 23 elements, including 11 heavy elements (Cu, Zn, Sr, Y, Zr, Ba, La, Ce, Nd, Sm, Eu) for up to 86 metal-poor (-2 < [Fe/H] < -1) subgiants. We use KORG,…
On the Origin of Abundance Variations in the Milky Way's High- Plateau
Tawny Sit, David H. Weinberg, Emily J. Griffith
Using multi-element abundances from the SDSS APOGEE survey, we investigate the origin of abundance variations in Milky Way (MW) disk stars on the "high- plateau," with $-0.5\leq…
Many elements matter: Detailed abundance patterns reveal star-formation and enrichment differences among Milky Way structural components
Emily J. Griffith, David W. Hogg, Sten Hasselquist +5
Many nucleosynthetic channels create the elements, but two-parameter models characterized by and Fe nonetheless predict stellar abundances in the Galactic disk to accuracies of…
The Milky Way Radial Metallicity Gradient as an Equilibrium Phenomenon: Why Old Stars are Metal-Rich
James W. Johnson, David H. Weinberg, Guillermo A. Blanc +12
Metallicities of both gas and stars decline toward large radii in spiral galaxies, a trend known as the radial metallicity gradient. We quantify the evolution of the metallicity gr…
2-process Model and Residual Abundance Analysis of the Milky Way Massive Satellites
Sten Hasselquist, Christian R. Hayes, Emily J. Griffith +4
The ``2-process Model'' is a promising technique for interpreting stellar chemical abundance data from large-scale surveys (e.g., SDSS-IV/V, GALAH), enabling more quantitative empi…
The Apache Point Observatory Galactic Evolution Experiment (APOGEE)
Steven R. Majewski, Ricardo P. Schiavon, Peter M. Frinchaboy +75
The Apache Point Observatory Galactic Evolution Experiment (APOGEE), one of the programs in the Sloan Digital Sky Survey III (SDSS-III), has now completed its systematic, homogeneo…
The First Data Release of the Sloan Digital Sky Survey
The SDSS collaboration, Kevork Abazajian
The Sloan Digital Sky Survey has validated and made publicly available its First Data Release. This consists of 2099 square degrees of five-band (u, g, r, i, z) imaging data, 186,2…
Retrieving Bulge and Disk Parameters and Asymptotic Magnitudes from the Growth Curves of Galaxies
Sadanori Okamura, Naoki Yasuda, Kazuhiro Shimasaku +2
We show that the growth curves of galaxies can be used to determine their bulge and disk parameters and bulge-to-total luminosity ratios, in addition to their conventional asymptot…
