Metallicity and -element Abundance Gradients along the Sagittarius Stream as Seen by APOGEE
Christian R. Hayes, Steven R. Majewski, Sten Hasselquist +27
Using 3D positions and kinematics of stars relative to the Sagittarius (Sgr) orbital plane and angular momentum, we identify 166 Sgr stream members observed by the Apache Point Obs…
In Pursuit of Galactic Archaeology: Astro2020 Science White Paper
Melissa Ness, Jonathan Bird, Jennifer Johnson +30
The next decade affords tremendous opportunity to achieve the goals of Galactic archaeology. That is, to reconstruct the evolutionary narrative of the Milky Way, based on the empir…
The Origin of Elements Across Cosmic Time: Astro2020 Science White Paper
Jennifer A. Johnson, Gail Zasowski, David Weinberg +14
The problem of the origin of the elements is a fundamental one in astronomy and one that has many open questions. Prominent examples include (1) the nature of Type Ia supernovae an…
The Detailed Science Case for the Maunakea Spectroscopic Explorer, 2019 edition
The MSE Science Team, Carine Babusiaux, Maria Bergemann +258
(Abridged) The Maunakea Spectroscopic Explorer (MSE) is an end-to-end science platform for the design, execution and scientific exploitation of spectroscopic surveys. It will unvei…
Stellar Astrophysics and Exoplanet Science with the Maunakea Spectroscopic Explorer (MSE)
Maria Bergemann, Daniel Huber, Vardan Adibekyan +70
The Maunakea Spectroscopic Explorer (MSE) is a planned 11.25-m aperture facility with a 1.5 square degree field of view that will be fully dedicated to multi-object spectroscopy. A…
The GALAH Survey: Chemodynamics of the Solar Neighbourhood
Michael R. Hayden, Joss Bland-Hawthorn, Sanjib Sharma +13
We present the chemodynamic structure of the solar neighbourhood using 62 814 stars within a 500 pc sphere of the Sun observed by GALAH and with astrometric parameters from Gaia DR…
Identifying Sagittarius Stream Stars By Their APOGEE Chemical Abundance Signatures
Sten Hasselquist, Jeffrey L. Carlin, Jon A. Holtzman +17
The SDSS-IV Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey provides precise chemical abundances of 18 chemical elements for 176,000 red giant stars d…
The Lazy Giants: APOGEE Abundances Reveal Low Star Formation Efficiencies in the Magellanic Clouds
David L. Nidever, Sten Hasselquist, Christian R. Hayes +28
We report the first APOGEE metallicities and alpha-element abundances measured for 3600 red giant stars spanning a large radial range of both the Large (LMC) and Small Magellanic C…
