The Apache Point Observatory extra-Galactic Evolution Experiment (APOeGEE): Chemical Abundance Trends for Seven Dwarf Spheroidal Galaxies in the APOGEE Survey
Matthew Shetrone, Rachael L. Beaton, Christian R. Hayes +10
In addition to comprehensive surveys of the Milky Way bulge, disk, and halo, the Apache Point Galactic Evolution Experiment (APOGEE) project observed seven dwarf spheroidal satelli…
A Galactic Self-Portrait: Density Structure and Integrated Properties of the Milky Way Disk
Julie Imig, Jon A. Holtzman, Gail Zasowski +23
The evolution history of the Milky Way disk is imprinted in the ages, positions, and chemical compositions of individual stars. In this study, we derive the intrinsic density distr…
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…
Chemical Cartography with APOGEE: Two-process Parameters and Residual Abundances for 288,789 Stars from Data Release 17
Tawny Sit, David H. Weinberg, Adam Wheeler +4
Stellar abundance measurements are subject to systematic errors that induce extra scatter and artificial correlations in elemental abundance patterns. We derive empirical calibrati…
Probing the early Milky Way with GHOST spectra of an extremely metal-poor star in the Galactic disk
Anya Dovgal, Kim A. Venn, Federico Sestito +31
Pristine_183.6849+04.8619 (P1836849) is an extremely metal-poor ([Fe/H]) star on a prograde orbit confined to the Galactic disk. Such stars are rare and may have their…
Small-scale stellar haloes: detecting low surface brightness features in the outskirts of Milky Way dwarf satellites
Jaclyn Jensen, Christian R. Hayes, Federico Sestito +5
Dwarf galaxies are valuable laboratories for dynamical studies related to dark matter and galaxy evolution, yet it is currently unknown just how physically extended their stellar c…
