A Tale of Two Disks: Mapping the Milky Way with the Final Data Release of APOGEE
Julie Imig, Cathryn Price, Jon A. Holtzman +24
We present new maps of the Milky Way disk showing the distribution of metallicity ([Fe/H]), -element abundances ([Mg/Fe]), and stellar age, using a sample of 66,496 red giant st…
The Eighteenth Data Release of the Sloan Digital Sky Surveys: Targeting and First Spectra from SDSS-V
Andrés Almeida, Scott F. Anderson, Maria Argudo-Fernández +151
The eighteenth data release of the Sloan Digital Sky Surveys (SDSS) is the first one for SDSS-V, the fifth generation of the survey. SDSS-V comprises three primary scientific progr…
Final Targeting Strategy for the SDSS-IV APOGEE-2N Survey
Rachael L. Beaton, Ryan J. Oelkers, Christian R. Hayes +57
APOGEE-2 is a dual-hemisphere, near-infrared (NIR), spectroscopic survey with the goal of producing a chemo-dynamical mapping of the Milky Way Galaxy. The targeting for APOGEE-2 is…
Chemical evolution of the Galactic bulge as traced by microlensed dwarf and subgiant stars. VIII. Carbon and oxygen
T. Bensby, A. Gould, M. Asplund +6
CONTEXT: [ABRIDGED]. For the Milky Way bulge, there are currently essentially no measurements of carbon in un-evolved stars, hampering our abilities to properly compare Galactic ch…
Nucleosynthesis signatures of neutrino-driven winds from proto-neutron stars: a perspective from chemical evolution models
Fiorenzo Vincenzo, Todd A. Thompson, David H. Weinberg +3
We test the hypothesis that the observed first-peak (Sr, Y, Zr) and second-peak (Ba) s-process elemental abundances in low-metallicity Milky Way stars, and the abundances of the el…
The SEGUE K Giant Survey. III. Quantifying Galactic Halo Substructure
William Janesh, Heather L. Morrison, Zhibo Ma +9
We statistically quantify the amount of substructure in the Milky Way stellar halo using a sample of 4568 halo K giant stars at Galactocentric distances ranging over 5-125 kpc. The…
The SEGUE K giant survey II: A Catalog of Distance Determinations for the SEGUE K giants in the Galactic Halo
Xiang-Xiang Xue, Zhibo Ma, Hans-Walter Rix +13
We present an online catalog of distance determinations for K giants, most of which are members of the Milky Way's stellar halo. Their medium-resolution spectra from SDS…
The chemical evolution of the Galactic Bulge seen through micro-lensing events
Sofia Feltzing, Thomas Bensby, Jorge Meléndez +6
Galactic bulges are central to understanding galaxy formation and evolution. Here we report on recent studies using micro-lensing events to obtain spectra of high resolution and mo…
SEGUE: A Spectroscopic Survey of 240,000 stars with g=14-20
II SEGUE Collaboration, Brian Yanny, Constance Rockosi +2
The SEGUE survey obtained 240,000 moderate resolution (R = 1800) spectra from 3900 - 9000 Angstroms of fainter Milky Way stars (14.0 < g < 20.3) of a wide variety of spectral types…
