The Nuclear Astrophysics program at n_TOF (CERN)

EPJ Web of Conferences, 2017
An important experimental program on Nuclear Astrophysics is being carried out at the n_TOF since several years, in order to address the still open issues in stellar and primordial nucleosynthesis.

Mixing and Magnetic Fields in Asymptotic Giant Branch Stars in the Framework of FRUITY Models

Universe, 2021
In the last few years, the modeling of asymptotic giant branch (AGB) stars has been much investigated, both focusing on nucleosynthesis and stellar evolution aspects. Recent advances in the input physics required for stellar computations made it possible

Probing the fission properties of neutron-rich actinides with the astrophysical r process [PDF]

EPJ Web of Conferences, 2020
We review recent work examining the influence of fission in rapid neutron capture (r-process) nucleosynthesis which can take place in astrophysical environments.

Stellar signatures of inhomogeneous big bang nucleosynthesis [PDF]

Physical Review D, 2020
We evaluate abundance anomalies generated in patches of the universe where the baryon-to-photon ratio was locally enhanced by possibly many orders of magnitude in the range $ = 10^{-10} - 10^{-1}$. Our study is motivated by the possible survival of rare dense regions in the early universe, the most extreme of which, above a critical threshold ...

Structure effects of 20N in elemental abundance estimations during explosive nucleosynthesis [PDF]

EPJ Web of Conferences
Most nuclei far from the valley of stability, and typically near the drip lines, exhibit exotic features that have challenged our current understanding of nuclear structure.

θ-dependence of light nuclei and nucleosynthesis

Physical Review Research, 2020
We investigate the impact of the QCD vacuum at nonzero θ on the properties of light nuclei, Big Bang nucleosynthesis, and stellar nucleosynthesis. Our analysis starts with a calculation of the θ-dependence of the neutron-proton mass difference and ...

The Influence of Nuclear Reactions and Nuclear Structure in Astrophysics

EPJ Web of Conferences, 2017
Nuclear reactions play an important role for the energy production and the nucleosynthesis in stars. New facilities, able to accelerate radioactive nuclei or high-intensity stable beams have allowed us to measure in the laboratory reactions involving ...

The s-process nucleosynthesis in massive stars: current status and uncertainties due to convective overshooting [PDF]

, 2012
Context: It is well known that the so-called s-process is responsible for the production of neutron-rich trans-iron elements, that form the bulk of the "heavy nuclides" (i.e.

Nucleosynthesis in Stellar Explosions [PDF]

, 1984
The final evolution and explosion of stars from 10 M⊙ to 106 M⊙ are reviewed with emphasis on factors affecting the expected nucleosynthesis. We order our paper in a sequence of decreasing mass. If, as many suspect, the stellar birth function was peaked towards larger masses at earlier times (see e.g., Silk 1977; but also see Palla, Salpeter, and ...
