Cool stars in the Galactic Center as seen by APOGEE: M giants, AGB stars and supergiant stars/candidates
M. Schultheis, A. Rojas-Arriagada, K. Cunha +11
The Galactic Center region, including the nuclear disk, has until recently been largely avoided in chemical census studies because of extreme extinction and stellar crowding. Makin…
APOGEE DR14/DR15 Abundances in the Inner Milky Way
G. Zasowski, M. Schultheis, S. Hasselquist +14
We present an overview of the distributions of 11 elemental abundances in the Milky Way's inner regions, as traced by APOGEE stars released as part of SDSS Data Release 14/15 (DR14…
The Milky Way bar and bulge revealed by APOGEE DR16 and Gaia EDR3
A. B. A. Queiroz, C. Chiappini, A. Perez-Villegas +23
We investigate the inner regions of the Milky Way with a sample of unprecedented size and coverage thanks to APOGEE DR16 and Gaia EDR3 data. Our inner Galactic sample has more than…
Chemical abundances of the young inner-disk open cluster NGC 6705 observed by APOGEE: sodium-rich and not -enhanced
V. Loaiza-Tacuri, K. Cunha, D. Souto +19
Previous results in the literature have found the young inner-disk open cluster NGC 6705 to be mildly -enhanced. We examined this possibility via an independent chemical abunda…
A chemical and kinematical analysis of the intermediate-age open cluster IC 166 from APOGEE and Gaia DR2
J. Schiappacasse-Ulloa, B. Tang, J. G. Fernández-Trincado +26
IC 166 is an intermediate-age open cluster ( Gyr) which lies in the transition zone of the metallicity gradient in the outer disc. Its location, combined with our very limi…
Chemical radial gradients for the bulge-bar stellar populations from the APOGEE survey
J. V. Sales-Silva, K. Cunha, V. V. Smith +20
The Milky Way bulge-bar is composed of multiple populations. Using chemical and kinematical planes, we segregate six populations in a bulge-bar sample observed by the APOGEE survey…
Target Selection for the Apache Point Observatory Galactic Evolution Experiment (APOGEE)
G. Zasowski, Jennifer A. Johnson, P. M. Frinchaboy +43
The Apache Point Observatory Galactic Evolution Experiment (APOGEE) is a high-resolution infrared spectroscopic survey spanning all Galactic environments (i.e., bulge, disk, and ha…
Open Cluster Chemical Homogeneity Throughout the Milky Way
Vijith Jacob Poovelil, G. Zasowski, S. Hasselquist +10
The chemical homogeneity of surviving stellar clusters contains important clues about interstellar medium (ISM) mixing efficiency, star formation, and the enrichment history of the…
How Many Components? Quantifying the Complexity of the Metallicity Distribution in the Milky Way Bulge with APOGEE
A. Rojas-Arriagada, G. Zasowski, M. Schultheis +14
We use data of 13,000 stars from the SDSS/APOGEE survey to study the shape of the bulge MDF within the region and , and spatially constr…
