Prospect for measurements of (γ, n) reaction cross-sections of p-nuclei at ELI-NP

open access: yesFrontiers in Astronomy and Space Sciences, 2023
The gamma beam system under construction at the ELI-NP facility in Romania is projected to give the nuclear physics community access to an experimental system providing a high-intensity, narrow bandwidth photon beam at variable energy.

QUÍMICA ESTELAR E ESTRELAS APOCALÍPTICAS: ESTUDO COMPARATIVO

open access: yesColloquium Exactarum, 2012
All atoms existing in the Universe, except Hydrogen (H) and helium (He), arise from processes occurring in stars and their evolution. The stars transmute the H and He in other heavier elements through nuclear fusion and its process rolling, filling and ...

Nucleosynthesis and Kilonovae from Strange Star Mergers

open access: yesUniverse, 2019
In this talk, we summarize the work in progress toward a full characterization of strange star−strange star (SS−SS) mergers related to the GW/GRB/kilonova events.

Positron Transport and Annihilation in the Galactic Bulge

open access: yesGalaxies, 2018
The annihilation of positrons in the Milky Way Galaxy has been observed for ∼50 years; however, the production sites of these positrons remains hard to identify.

Big bang nucleosynthesis [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 1999
The concordance of standard big bang nucleosynthesis theory and the related observations of the light element isotopes (including some new higher \he4 abundances) will be reviewed. Implications of BBN on chemical evolution, dark matter and constraints on particle properties will be discussed.

The s-process Nucleosynthesis [PDF]

open access: yesProceedings of the International Astronomical Union, 2005
Theoretical as well as observational aspects of the s-process nucleosynthesis are reviewed. The classical site-independent s-process model as well as the s-process in massive stars are shortly described. A special attention is paid to the nucleosynthesis taking place in AGB stars and the extra-mixing invoked to explain the production of neutrons in the

Nuclear reactions involving light elements & BBN [PDF]

open access: yesEPJ Web of Conferences
Light elements play a key role in different scenario in astrophysics, ranging from primordial nucleosynthesis up to stellar nucleosynthesis and cosmic ray nucleosynthesis.

Leptonic photons and nucleosynthesis [PDF]

open access: yesPhysics Letters B, 1997
Should $U(1)$ long-range forces be associated to electron, muon and/or tau quantum number then their ''fine structure constants" are seen to be bound by nucleosynthesis data to be less than about $1.7 \times 10^{-11}$.
