Chemical Evolution of R-process Elements in Stars (CERES). III. Chemical abundances of neutron capture elements from Ba to Eu
L. Lombardo, C. J. Hansen, F. Rizzuti +11
The chemical abundances of elements such as barium and the lanthanides are essential to understand the nucleosynthesis of heavy elements in the early Universe as well as the contri…
Chemical Evolution of R-process Elements in Stars (CERES): IV. An observational run-up of the third r-process peak with Hf, Os, Ir, and Pt
Arthur Alencastro Puls, Jan Kuske, Camilla Juul Hansen +8
The third r-process peak (Os, Ir, Pt) is poorly understood due to observational challenges, with spectral lines located in the blue or near-ultraviolet region of stellar spectra. T…
Chemical Evolution of R-process Elements in Stars (CERES) II. The impact of stellar evolution and rotation on light and heavy elements
Raphaela Fernandes de Melo, Linda Lombardo, Arthur Alencastro Puls +4
Context. Carbon, nitrogen, and oxygen are the most abundant elements throughout the universe, after hydrogen and helium. Studying these elements in low-metallicity stars can provid…
HR-GO I: Comprehensive NLTE abundance analysis of the Cetus stream
T. M. Sitnova, Z. Yuan, T. Matsuno +8
Dwarf galaxy streams encode vast amounts of information essential to understanding early galaxy formation and nucleosynthesis channels. Due to the variation in the timescales of st…
MINCE II. Neutron capture elements
P. François, G. Cescutti, P. Bonifacio +24
The MINCE (Measuring at Intermediate metallicity Neutron-Capture Elements) project aims to gather the abundances of neutron-capture elements but also of light elements and iron pea…
High-speed stars. II. An unbound star, young stars, bulge metal-poor stars, and Aurora candidates
P. Bonifacio, E. Caffau, L. Monaco +6
The data from the Gaia satellite led us to revise our conception of the Galaxy structure and history. Hitherto unknown components have been discovered and a deep re-thinking of wha…
