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 Bulge Cluster Origin (BulCO) survey with CRIRES at the ESO-VLT: a chemical screening of the Globular Cluster NGC 6553
A. Bartolomei, L. Origlia, C. Fanelli +10
In this paper we present the chemical screening of the stellar population belonging to the globular cluster NGC 6553 in the Galactic bulge. This study has been conducted in the con…
How homogeneous was the chemical enrichment of the Milky Way 13 gigayears ago?
Riano E. Giribaldi, Laura Magrini, Martina Rossi +3
We reanalyze the chemical composition of the metal-poorest tail of the Galactic halo using highly accurate atmospheric parameters Giribaldi et al. (2021, 2023) and cutting-edge 3D…
The metal-poorest tail of the Galactic halo: hypothesis on its origin from precise spectral analysis
Riano E. Giribaldi, Laura Magrini, Martina Rossi +3
The origin of the Galactic halo is one of the fundamental topics linking the study of galaxy formation and evolution to cosmology. We aim at deriving precise and accurate stellar p…
