A view of the H-band light-element chemical patterns in Globular Clusters under the AGB self-enrichment scenario
F. Dell'Agli, D. A. García-Hernández, P. Ventura +7
We discuss the self-enrichment scenario by AGB stars for the formation of multiple populations in globular clusters (GCs) by analyzing data set of giant stars observed in 9 Galacti…
Target Selection for the SDSS-IV APOGEE-2 Survey
G. Zasowski, R. E. Cohen, S. D. Chojnowski +34
APOGEE-2 is a high-resolution, near-infrared spectroscopic survey observing roughly 300,000 stars across the entire sky. It is the successor to APOGEE and is part of the Sloan Digi…
Carbon-enhanced metal-poor stars in the SDSS-APOGEE database
Collin L. Kielty, Kim A. Venn, Nicholas B. Loewen +5
We identify six new CEMP stars ([C/Fe]>+0.7 and [Fe/H]< -1.8) and another seven likely candidates within the APOGEE database following Data Release 12. These stars have chemical co…
