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…
From the bulge to the outer disc: StarHorse stellar parameters, distances, and extinctions for stars in APOGEE DR16 and other spectroscopic surveys
A. B. A. Queiroz, F. Anders, C. Chiappini +27
We combine high-resolution spectroscopic data from APOGEE-2 Survey Data Release 16 (DR16) with broad-band photometric data from several sources, as well as parallaxes from {\it Gai…
Homogeneous Analysis of Globular Clusters from the APOGEE Survey with the BACCHUS Code. II. The Southern Clusters and Overview
Szabolcs Mészáros, Thomas Masseron, D. A. García-Hernández +33
We investigate the Fe, C, N, O, Mg, Al, Si, K, Ca, Ce and Nd abundances of 2283 red giant stars in 31 globular clusters from high-resolution spectra observed in both the northern a…
Two Ultra-Faint Milky Way Stellar Systems Discovered in Early Data from the DECam Local Volume Exploration Survey
S. Mau, W. Cerny, A. B. Pace +56
We report the discovery of two ultra-faint stellar systems found in early data from the DECam Local Volume Exploration survey (DELVE). The first system, Centaurus I (DELVE J1238-40…
Stellar population models based on the SDSS-IV MaStar library of stellar spectra. I. Intermediate-age/old models
C. Maraston, L. Hill, D. Thomas +14
We use the first release of the SDSS/MaStar stellar library comprising ~9000, high S/N spectra, to calculate integrated spectra of stellar population models. The models extend over…
On the nature of a shell of young stars in the outskirts of the Small Magellanic Cloud
David Martinez-Delgado, A. Katherina Vivas, Eva K. Grebel +35
Understanding the evolutionary history of the Magellanic Clouds requires an in-depth exploration and characterization of the stellar content in their outer regions, which ultimatel…
Astro2020 Science White Paper: Are Supernovae the Dust Producer in the Early Universe?
Jeonghee Rho, Danny Milisavljevic, Arkaprabha Sarangi +23
Whether supernovae are a significant source of dust has been a long-standing debate. The large quantities of dust observed in high-redshift galaxies raise a fundamental question as…
Achieving Transformative Understanding of Extreme Stellar Explosions with ELT-enabled Late-time Spectroscopy
D. Milisavljevic, R. Margutti, R. Chornock +35
Supernovae are among the most powerful and influential explosions in the universe. They are also ideal multi-messenger laboratories to study extreme astrophysics. However, many fun…
Close companions around young stars
Marina Kounkel, Kevin Covey, Maxwell Moe +26
Multiplicity is a fundamental property that is set early during stellar lifetimes, and it is a stringent probe of the physics of star formation. The distribution of close companion…
Multi-Messenger Astronomy with Extremely Large Telescopes
Ryan Chornock, Philip S. Cowperthwaite, Raffaella Margutti +82
The field of time-domain astrophysics has entered the era of Multi-messenger Astronomy (MMA). One key science goal for the next decade (and beyond) will be to characterize gravitat…
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…
