The nucleosynthesis of Ba in the Early Universe. Constraints from elemental abundances and isotopic ratios
Riano E. Giribaldi, Marco Palla, Laura Magrini +6
The [Ba/Eu] abundance ratio is commonly adopted as a tracer of the relative contributions of the slow (s) and rapid (r) neutron-capture processes. However, at [Fe/H] < -2 dex, Ba c…
The LEGARE Project. I. Chemical evolution model of the Nuclear Stellar Disc in a Bayesian framework
E. Spitoni, M. Schultheis, F. Matteucci +5
The Nuclear Stellar Disc (NSD) of the Milky Way is a dense, rotating stellar system in the central 200 pc. The NSD is thought to be primarily fuelled by bar-driven gas inflows from…
Fluorine Evolution in the Galactic Halo
Valeria Grisoni, Federico Rizzuti, Gabriele Cescutti
The chemical evolution of fluorine is still a matter of debate in Galactic archaeology, especially at low metallicities, where it is particularly challenging to obtain the correspo…
Impact of AGB stars on the chemical evolution of neutron-capture elements
Gabriele Cescutti, Francesca Matteucci
In this paper we discuss the impact of the s-process nucleosynthesis in Asymptotic Giant Branch stars on the enrichment of heavy elements. We review the main steps made on this sub…
Lithium evolution in the Galactic thin disc from Main-Sequence and early Red-Giant-Branch stars
C. T. Nguyen, G. Cescutti, F. Matteucci +7
The role of novae as producers of galactic lithium has been suggested since the 1970s, and it has been reconsidered recently with the detection of Be in their outbursts. At the…
PARSEC V2.0: Rotating tracks and isochrones for seven addtional metallicities in the range Z=0.0001-0.03
C. T. Nguyen, G. Costa, A. Bressan +10
PARSEC v2.0 rotating stellar tracks were previously presented for six values of metallicity from subsolar to solar values, with initial rotation rates (, defined as…
