Detailed abundances in the Galactic center: Evidence of a metal-rich alpha-enhanced stellar population
B. Thorsbro, N. Ryde, R. M. Rich +8
We present a detailed study of the composition of 20 M giants in the Galactic center with 15 of them confirmed to be in the Nuclear Star Cluster. As a control sample we have also o…
Fluorine in the solar neighbourhood: the need for several cosmic sources
Nils Ryde, Henrik Jönsson, Gregory Mace +14
The cosmic origin of fluorine is still not well constrained. Several nucleosynthetic channels at different phases of stellar evolution have been suggested, but these must be constr…
Stellar Population Astrophysics (SPA) with the TNG: Identification of a Sulphur line at lambda(air) = 1063.600nm in GIANO-B stellar spectra
N. Ryde, H. Hartman, E. Oliva +6
Context. In the advent of new infrared, high-resolution spectrometers, accurate and precise atomic data in the infrared is urgently needed. Identifications, wavelengths, strengths,…
The inner two degrees of the Milky Way. Evidence of a chemical difference between the Galactic Center and the surrounding inner bulge stellar populations
M. Schultheis, R. M. Rich, L. Origlia +4
Although there have been numerous studies of chemical abundances in the Galactic bulge, the central two degrees have been relatively unexplored due to the heavy and variable inters…
Abundances of disk and Bulge giants from high-resolution optical spectra III. Sc, V, Cr, Mn, Co, Ni
M. Lomaeva, H. Jönsson, N. Ryde +2
Context. Recent observations of the Bulge, e.g., its X-shape, cylindrical stellar motions, and a potential fraction of young stars propose that it formed through secular evolution…
Detailed Abundances for the Old Population near the Galactic Center: I. Metallicity distribution of the Nuclear Star Cluster
R. M. Rich, N. Ryde, B. Thorsbro +4
We report the first high spectral resolution study of 17 M giants kinematically confirmed to lie within a few parsecs of the Galactic Center, using R=24,000 spectroscopy from Keck/…
