X-shooter spectroscopy of giant stars in the nuclear star cluster
L. Origlia, C. Fanelli, A. Mucciarelli +5
Near-IR spectra of a homogeneous sample of 15 red giants in the Galactic nuclear star cluster, within 1.5 pc of SgrA*, have been acquired with X-shooter at the Very Large Telescope…
CRIRES+ reveals the chemistry of the stellar sub-populations in the bulge fossil fragment Liller 1
L. Chiappino, L. Origlia, C. Fanelli +10
In this paper we present the chemical screening of the complex stellar population discovered in the Bulge Fossil Fragment Liller 1. This study is part of the Bulge Cluster Origin (…
The multi-age stellar populations of Terzan 5 as revealed by JWST
G. Zullo, C. Pallanca, F. R. Ferraro +10
The James Webb Space Telescope provides an exciting opportunity to investigate stellar systems located in heavily obscured regions like the Galactic bulge. Possibly, the most enigm…
Stellar rotation in the intermediate-age massive cluster NGC 1783: clues on the nature of UV-dim stars
Silvia Leanza, Emanuele Dalessandro, Mario Cadelano +9
Over the past decade, stellar rotation has emerged as a key factor in shaping the morphology of color-magnitude diagrams of young and intermediate-age star clusters. In this study,…
On the manifest link between Terzan 5 and the Galactic bulge
L. Origlia, F. R. Ferraro, C. Fanelli +4
We address the chemical link between Terzan 5 (hereafter Ter5) and the Bulge, as probed by the observed distributions of [/Fe] abundance ratios with varying [Fe/H] and by suita…
The Bulge Cluster Origin (BulCO) survey at the ESO-VLT: probing the early history of the Milky Way assembling. Design and first results in Liller1
F. R. Ferraro, L. Chiappino, A. Bartolomei +14
We present the scientific goals and the very first results of the Bulge Cluster Origin (BulCO) survey. This survey has been specifically designed to perform an unprecedented chemic…
