Modelling chemical clocks -- Theoretical evidences of the space and time evolution of [s/alpha] in the Galactic disc with Gaia-ESO survey
Marta Molero, Laura Magrini, Marco Palla +6
Chemical clocks based on [s-process elements/alpha-elements] ratios are widely used to estimate ages of Galactic stellar populations. However, the [s/alpha] vs. age relations are n…
Yields from massive stars in binaries. Chemical evolution of the Milky Way disk
E. Pepe, M. Palla, F. Matteucci +1
A large fraction of massive stars in the Galaxy reside in binary systems and their evolution is different from that of single stars. The yields of massive stars, which are the main…
Chemical Abundances in the Nuclear Star Cluster of the Milky Way: alpha-Element Trends and Their Similarities with the Inner Bulge
N. Ryde, G. Nandakumar, M. Schultheis +15
A chemical characterization of the Galactic Center is essential for understanding its formation and structural evolution. Trends of alpha-elements, such as Mg, Si, and Ca, serve as…
Constraints on the history of Galactic spiral arms revealed by Gaia GSP-Spec alpha-elements
M. Barbillon, A. Recio-Blanco, E. Poggio +4
The distribution of chemical elements in the Galactic disc can reveal fundamental clues on the physical processes that led to the current configuration of our Galaxy. We map chemic…
