Homogeneous Analysis of Globular Clusters from the APOGEE Survey with the BACCHUS Code III. Cen
Szabolcs Mészáros, Thomas Masseron, José G. Fernández-Trincado +18
We study the multiple populations of Cen by using the abundances of Fe, C, N, O, Mg, Al, Si, K, Ca, and Ce from the high-resolution, high signal-to-noise (S/N70) spectra of…
The Rotation of Selected Globular Clusters and the Differential Rotation of M3 in Multiple Populations from the SDSS-IV APOGEE-2 Survey
László Szigeti, Szabolcs Mészáros, Gyula M. Szabó +3
In this paper, we analyze 10 globular clusters in order to measure their rotational properties by using high precision radial velocity data from the SDSS-IV APOGEE-2 survey. Out of…
APOGEE Data and Spectral Analysis from SDSS Data Release 16: Seven Years of Observations Including First Results from APOGEE-South
Henrik Jönsson, Jon A. Holtzman, Carlos Allende Prieto +20
The spectral analysis and data products in Data Release 16 (DR16; December 2019) from the high-resolution near-infrared APOGEE-2/SDSS-IV survey are described. Compared to the previ…
The Chemical Compositions of Accreted and {\it in situ} Galactic Globular Clusters According to SDSS/APOGEE
Danny Horta, Ricardo P. Schiavon, J. Ted Mackereth +16
Studies of the kinematics and chemical compositions of Galactic globular clusters (GCs) enable the reconstruction of the history of star formation, chemical evolution, and mass ass…
Discovery of a nitrogen-enhanced mildly metal-poor binary system: Possible evidence for pollution from an extinct AGB Star
José G. Fernández-Trincado, Ronald Mennickent, Mauricio Cabezas +13
We report the serendipitous discovery of a nitrogen-rich, mildly metal-poor ([Fe/H]=-1.08) giant star in a single-lined spectroscopic binary system found in the SDSS-IV Apache Poin…
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…
