Spectroscopic age estimates for APOGEE red-giant stars: Precise spatial and kinematic trends with age in the Galactic disc
F. Anders, P. Gispert, B. Ratcliffe +12
Over the last few years, many studies have found an empirical relationship between the abundance of a star and its age. Here we estimate spectroscopic stellar ages for 178 825 red-…
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…
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…
Red giants observed by CoRoT and APOGEE: The evolution of the Milky Way's radial metallicity gradient
F. Anders, C. Chiappini, I. Minchev +21
Using combined asteroseismic and spectroscopic observations of 418 red-giant stars close to the Galactic disc plane (6 kpc kpc, kpc), w…
Chemical tagging with APOGEE: Discovery of a large population of N-rich stars in the inner Galaxy
Ricardo P. Schiavon, Olga Zamora, Ricardo Carrera +42
Formation of globular clusters (GCs), the Galactic bulge, or galaxy bulges in general, are important unsolved problems in Galactic astronomy. Homogeneous infrared observations of l…
Galactic Archaeology with asteroseismology and spectroscopy: Red giants observed by CoRoT and APOGEE
F. Anders, C. Chiappini, T. S. Rodrigues +42
With the advent of the space missions CoRoT and Kepler, it has become feasible to determine precise asteroseismic masses and ages for large samples of red-giant stars. In this pape…
