Tracing the W3/W4/W5 and Perseus complex dynamical evolution with star clusters
A. Della Croce, E. Dalessandro, E. Vesperini +4
The Perseus complex offers an ideal testbed to study cluster formation and early evolution as it hosts two major hierarchical structures (namely LISCA I and LISCA II) and the W3/W4…
Multi-iron subpopulations in Liller 1 from high resolution H-band spectroscopy
C. Fanelli, L. Origlia, R. M. Rich +7
We present a high resolution chemical study of a representative sample of 21 luminous giant stars of Liller~1, a complex stellar system in the Galactic bulge, based on H band spect…
X-shooter spectroscopy of Liller1 giant stars
D. A. Alvarez Garay, C. Fanelli, L. Origlia +8
We present the first comprehensive chemical study of a representative sample of 27 luminous red giant branch (RGB) stars belonging to Liller 1, a complex stellar system in the Gala…
Stellar Population Astrophysics (SPA) with TNG, Fluorine abundances in seven open clusters
Shilpa Bijavara Seshashayana, Henrik Jönsson, Valentina D'Orazi +9
The age, evolution, and chemical properties of the Galactic disk can be effectively ascertained using open clusters. Within the large program Stellar Populations Astrophysics at th…
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…
Evidence against anomalous compositions for giants in the Galactic Nuclear Star Cluster
B. Thorsbro, N. Ryde, M. Schultheis +5
Very strong Sc I lines have been found recently in cool M giants in the Nuclear Star Cluster in the Galactic Center. Interpreting these as anomalously high scandium abundances in t…
Three candidate double clusters in the LMC: truth or dare?
E. Dalessandro, A. Zocchi, A. L. Varri +6
The Large Magellanic Cloud (LMC) hosts a large number of candidate stellar cluster pairs. Binary stellar clusters provide important clues about cluster formation processes and the…
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/…
Detailed near-IR stellar abundances of red giants in the Inner Bulge and Galactic Center
N. Ryde, R. M. Rich, B. Thorsbro +3
Owing to their extreme crowding and high and variable extinction, stars in the Galactic Bulge, within +-2 degrees of the Galactic plane, and especially those in the Nuclear Star Cl…
Detailed abundance analysis of a metal-poor giant in the Galactic Center
N. Ryde, T. K. Fritz, R. M. Rich +4
We report the first results from our program to examine the metallicity distribution of the Milky Way nuclear star cluster connected to SgrA*, with the goal of inferring the star f…
