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…

Evidence for a metal-poor population in the inner Galactic Bulge

M. Schultheis, K. Cunha, G. Zasowski +14

The inner Galactic Bulge has, until recently, been avoided in chemical evolution studies due to extreme extinction and stellar crowding. Large, near-IR spectroscopic surveys, such…

Mixed Early and Late-Type Properties in the Bar of NGC 6221: Evidence for Evolution along the Hubble Sequence?

J. C. Vega Beltran, W. W. Zeilinger, P. Amico +5

Rotation curves and velocity dispersion profiles are presented for both the stellar and gaseous components along five different position angles (P.A.=5, 50, 95, 125 and 155 degrees…
