s-Processing in Asymptotic Giant Branch Stars in the Light of Revised Neutron-Capture Cross Sections

open access: yesUniverse, 2021
Current AGB stellar models provide an adequate description of the s-process nucleosynthesis that occurs. Nonetheless, they still suffer from many uncertainties related to the modeling of the 13C pocket formation and the adopted nuclear reaction rates ...

Pygmy resonances and nucleosynthesis [PDF]

open access: yesEPJ Web of Conferences, 2015
A microscopic theoretical approach based on a self-consistent density functional theory for the nuclear ground state and QRPA formalism extended with multi-phonon degrees of freedom for the nuclear excited states is implemented in investigations of new low-energy modes called pygmy resonances.

R-Process with Magnetized Nuclei at Dynamo-Explosive Supernovae and Neutron Star Mergers

open access: yesUniverse, 2021
Nucleosynthesis at latge magnetic induction levels relevant to core-collapse supernovae and neutron star mergers is considered. For respective magnetic fields of a strength up to ten teratesla, atomic nuclei exhibit a linear magnetic response due to the ...

Following Fission Products in Explosive Astrophysical Environments [PDF]

open access: yesEPJ Web of Conferences, 2020
The astrophysical process by which the heaviest elements are formed in the universe is known as the rapid neutron capture process, or r process, of nucleosynthesis.

Nuclear Reactions For Nucleosynthesis Beyond Fe [PDF]

open access: yes, 2015
Many more nuclear transitions have to be known in the determination of stellar reactivities for trans-iron nucleosynthesis than for reactions of light nuclei. This requires different theoretical and experimental approaches.

Nucleosynthesis Predictions and High-Precision Deuterium Measurements

open access: yesUniverse, 2017
Two new high-precision measurements of the deuterium abundance from absorbers along the line of sight to the quasar PKS1937–1009 were presented. The absorbers have lower neutral hydrogen column densities (N(HI) ≈ 18 cm − 2 ) than for previous ...

Proton-rich nucleosynthesis and nuclear physics [PDF]

open access: yes, 2012
Although the detailed conditions for explosive nucleosynthesis are derived from astrophysical modeling, nuclear physics determines fundamental patterns in abundance yields, not only for equilibrium processes. Focussing on the nu p- and the gamma-process,

The Nuclear Astrophysics program at n_TOF (CERN)

open access: yesEPJ 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.
