Over the last three years, the rates of all the main nuclear reactions involving the destruction and production of 26Al in stars (26Al(n, p)26Mg, 26Al(n, α)23Na, 26Al(p, γ)27Si and 25Mg(p, γ)26Al) have been re-evaluated thanks to new high-precision e...

The cosmic production of the short-lived radioactive nuclide 26Al is crucial for our understanding of the evolution of stars and galaxies. However, simulations of the stellar sites producing 26Al are still weakened by significant nuclear uncertaintie...

The NuGrid AGB Evolution and Nucleosynthesis Data Set (2022)
Journal Article
Battino, U., Pignatari, M., Tattersall, A., Denissenkov, P., & Herwig, F. (2022). The NuGrid AGB Evolution and Nucleosynthesis Data Set. Universe, 8(3), Article 170. https://doi.org/10.3390/universe8030170

Asymptotic Giant Branch (AGB) stars play a key role in the chemical evolution of galaxies. These stars are the fundamental stellar site for the production of light elements such as C, N and F, and half of the elements heavier than Fe via the slow neu...

We studied α cluster states in Mg26 via the Ne22(Li6,dγ)Mg26 reaction in inverse kinematics at an energy of 7 MeV/nucleon. States between Ex = 4-14 MeV in Mg26 were populated and relative α spectroscopic factors were determined. Some of these states...

Slow White Dwarf Mergers as a New Galactic Source of Trans-Iron Elements (2021)
Presentation / Conference Contribution
Battino, U., Lederer-Woods, C., Travaglio, C., Röpke, F. K., & Gibson, B. (2021, September). Slow White Dwarf Mergers as a New Galactic Source of Trans-Iron Elements. Paper presented at 16th Symposium on Nuclei in the Cosmos, NIC-XVI 2021, Chengdu, China

The astrophysical origins of the heaviest stable elements that we observe today in the Solar System are still not fully understood. Recent studies have demonstrated that H-accreting white dwarfs (WDs) in a binary system exploding as type Ia supernova...
