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…

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…

Shaping Galactic Habitability: the impact of stellar migration and gas giants

E. Spitoni, M. Palla, L. Magrini +9

In exoplanet research, the focus is increasingly on identifying Earth analogs, planets similar in density and habitability potential. As the number of rocky exoplanets grows, paral…

High N/O ratio at high redshift as a result of a strong burst of star formation and differential galactic winds

F. Rizzuti, F. Matteucci, P. Molaro +2

Recent observations by JWST have revealed supersolar N abundances in galaxies at very high redshift. On the other hand, these galaxies show subsolar metallicity. The observe…

Explaining the ratio in the Galactic halo: the contribution from shell mergers in primordial massive stars

F. Rizzuti, G. Cescutti, P. Molaro +5

Recent campaigns of observations have provided new measurements of the carbon isotopes in the most metal-poor stars of the Galaxy. These stars are so metal-poor that they could onl…
