Imaging neutron capture cross sections: i-TED proof-of-concept and future prospects based on Machine-Learning techniques
V. Babiano-Suárez, J. Lerendegui-Marco, J. Balibrea-Correa +132
i-TED is an innovative detection system which exploits Compton imaging techniques to achieve a superior signal-to-background ratio in () cross-section measurements using time-…
s-Processing in AGB Stars Revisited. III. Neutron captures from MHD mixing at different metallicities and observational constraints
Maurizio Busso, Diego Vescovi, Sara Palmerini +2
We present post process neutron capture computations for Asymptotic Giant Branch stars of 1.5 to 3 Mo and metallicities -1.3 to 0.1. The reference stellar models are computed with…
On the mass and metallicity distribution of parent AGB stars of presolar SiC
Sergio Cristallo, Ambra Nanni, Gabriele Cescutti +5
The vast majority (>=90%) of presolar SiC grains identified in primitive meteorites are relics of ancient asymptotic giant branch (AGB) stars, whose ejecta were incorporated into t…
The luminosity constraint in the era of precision solar physics
Diego Vescovi, Carlo Mascaretti, Francesco Vissani +2
The luminosity constraint is a very precise relationship linking the power released by the Sun as photons and the solar neutrino fluxes. Such a relation, which is a direct conseque…
Production of very light elements and strontium in the early ejecta of neutron star mergers
A. Perego, D. Vescovi, A. Fiore +10
We study the production of very light elements () in the dynamical and spiral-wave wind ejecta of binary neutron star mergers by combining detailed nucleosynthesis calculat…
Magnetic-buoyancy Induced Mixing in AGB Stars: Presolar SiC Grains
Diego Vescovi, Sergio Cristallo, Maurizio Busso +1
Isotope ratios can be measured in presolar SiC grains from ancient Asymptotic Giant Branch (AGB) stars at permil-level (0.1\%) precision. Such precise grain data permit derivation…
Modeling the formation of the C neutron source in AGB stars
Diego Vescovi, Sergio Cristallo
A major source of uncertainty in AGB models is the partial-mixing process of hydrogen, required for the formation of the so-called C pocket. Among the attempts to derive a s…
