Chemical Abundances of M-dwarfs from the APOGEE Survey. I. The Exoplanet Hosting Stars Kepler-138 and Kepler-186
Diogo Souto, Katia Cunha, D. A. Garcia-Hernandez +18
We report the first detailed chemical abundance analysis of the exoplanet-hosting M-dwarf stars Kepler-138 and Kepler-186 from the analysis of high-resolution ( 22,500) $…
APOGEE Chemical Abundances of Globular Cluster Giants in the Inner Galaxy
Ricardo P. Schiavon, Jennifer A. Johnson, Peter M. Frinchaboy +27
We report chemical abundances obtained by SDSS-III/APOGEE for giant stars in five globular clusters located within 2.2 kpc of the Galactic centre. We detect the presence of multipl…
Two Groups of Red Giants with Distinct Chemical Abundances in the Bulge Globular Cluster NGC 6553 Through the Eyes of APOGEE
Baitian Tang, Roger E. Cohen, Doug Geisler +18
Multiple populations revealed in globular clusters (GCs) are important windows to the formation and evolution of these stellar systems. The metal-rich GCs in the Galactic bulge are…
Infrared High-Resolution Integrated Light Spectral Analyses of M31 Globular Clusters from APOGEE
Charli M. Sakari, Matthew D. Shetrone, Ricardo P. Schiavon +10
Chemical abundances are presented for 25 M31 globular clusters (GCs), based on moderately high resolution (R = 22, 500) H-band integrated light spectra from the Apache Point Observ…
Galactic planetary nebulae with precise nebular abundances as a tool to understand the evolution of asymptotic giant branch stars
D. A. Garcia-Hernandez, P. Ventura, G. Delgado-Inglada +3
We present nucleosynthesis predictions (HeCNOCl) from asymptotic giant branch (AGB) models, with diffusive overshooting from all the convective borders, in the metallicity range Z/…
On the formation of molecules and solid-state compounds from the AGB to the PN phases
D. A. Garcia-Hernandez, A. Manchado
During the asymptoyic giant branch (AGB) phase, different elements are dredge-up to the stellar surface depending on progenitor mass and metallicity. When the mass loss increases a…
