Nuclear Reactions For Nucleosynthesis Beyond Fe [PDF]
, 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
Universe, 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 ...

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

Proton-rich nucleosynthesis and nuclear physics [PDF]
, 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,

Pygmy resonances and nucleosynthesis [PDF]
EPJ 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.

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

Annual Review of Nuclear and Particle Science, 1984 This article provides a review of the present status of research in nucleosynthesis, with emphasis on problems of nucleosynthesis in stellar and supernova environments. The authors begin by surveying abundance patterns in the Sun, our galaxy and other galaxies, calling attention to the manner in which such data serve to guide and to restrict ...

Revisiting big-bang nucleosynthesis constraints on long-lived decaying particles [PDF]
, 2017 The authors provide a state of the art analysis of the effects of long-lived non-Standard Model massive particles, decaying during big-bang nucleosynthesis (BBN), on the primordial abundances of light elements. Besides updated standard BBN reaction rates,
