Neutrino Nucleosynthesis of radioactive nuclei in supernovae [PDF]

, 2015
We study the neutrino-induced production of nuclides in explosive supernova nucleosynthesis for progenitor stars with solar metallicity and initial main sequence masses between 15 M$_\odot$ and 40 M$_\odot$. We improve previous investigations i) by using

Mergers of Binary Neutron Star Systems: A Multimessenger Revolution

Frontiers in Astronomy and Space Sciences, 2021
On August 17, 2017, less than two years after the direct detection of gravitational radiation from the merger of two∼30 M⊙ black holes, a binary neutron star merger was identified as the source of a gravitational wave signal of ∼100 s duration that ...

Big bang nucleosynthesis [PDF]

Nuclear 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.

Neutron-Driven Nucleosynthesis in Stellar Plasma

Frontiers in Physics, 2022
A large uncertainty for the slow neutron capture nucleosynthesis (s-process) models is caused by the amount of neutrons available to the process itself.

Nucleosynthesis of $^{92}$Nb and the relevance of the low-lying isomer at 135.5 keV [PDF]

, 2016
Background: Because of its half-life of about 35 million years, 92Nb is considered as a chronometer for nucleosynthesis events prior to the birth of our sun. The abundance of 92Nb in the early solar system can be derived from meteoritic data.

Nucleosynthesis in the Early Galaxy [PDF]

The Astrophysical Journal, 2007
Recent observations of r-process-enriched metal-poor star abundances reveal a non-uniform abundance pattern for elements $Z\leq47$. Based on non-correlation trends between elemental abundances as a function of Eu-richness in a large sample of metal-poor stars, it is shown that the mixing of a consistent and robust light element primary process (LEPP ...

Direct reactions for astrophysical p-capture rates with ORRUBA and GODDESS

Frontiers in Physics
Understanding the nucleosynthesis and energy generation in quiescent and explosive stellar burning requires a detailed understanding of reaction rates on many unstable nuclides.

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.

Explosive Nucleosynthesis of Weak r-Process Elements in Extremely Metal-Poor Core-Collapse Supernovae

, 2008
There have been attempts to fit the abundance patterns of extremely metal-poor stars with supernova nucleosynthesis models for the lighter elements than Zn. On the other hand, observations have revealed that the presence of EMP stars with peculiarly high
