BACCHUS Analysis of Weak Lines in APOGEE Spectra (BAWLAS)
Christian R. Hayes, Thomas Masseron, Jennifer Sobeck +11
Elements with weak and blended spectral features in stellar spectra are challenging to measure and require specialized analysis methods to precisely measure their chemical abundanc…
Exploring the Galactic Warp Through Asymmetries in the Kinematics of the Galactic Disk
Xinlun Cheng, Borja Anguiano, Steven R. Majewski +10
Previous analyses of large databases of Milky Way stars have revealed the stellar disk of our Galaxy to be warped and that this imparts a strong signature on the kinematics of star…
Spatial variations in the Milky Way disc metallicity-age relation
Diane K. Feuillet, Neige Frankel, Karin Lind +5
Stellar ages are a crucial component to studying the evolution of the Milky Way. Using Gaia DR2 distance estimates, it is now possible to estimate stellar ages for a larger volume…
APOGEE Chemical Abundances of the Sagittarius Dwarf Galaxy
Sten Hasselquist, Matthew Shetrone, Verne Smith +23
The Apache Point Observatory Galactic Evolution Experiment (APOGEE) provides the opportunity to measure elemental abundances for C, N, O, Na, Mg, Al, Si, P, K, Ca, V, Cr, Mn, Fe, C…
An Infrared Diffuse Circumstellar Band? The Unusual 1.5272 Micron DIB In the Red Square Nebula
G. Zasowski, S. Drew Chojnowski, D. G. Whelan +3
The molecular carriers of the ubiquitous absorption features called the diffuse interstellar bands (DIBs) have eluded identification for many decades, in part because of the enormo…
Abundances, Stellar Parameters, and Spectra From the SDSS-III/APOGEE Survey
Jon A. Holtzman, Matthew Shetrone, Jennifer A. Johnson +39
The SDSS-III/APOGEE survey operated from 2011-2014 using the APOGEE spectrograph, which collects high-resolution (R~22,500), near-IR (1.51-1.70 microns) spectra with a multiplexing…
