The Impact of Recent LUNA Measurements of NeNa Reactions on ²⁶Al Stellar Nucleosynthesis

Universe
Recent measurements performed by the LUNA(Laboratory for Underground Nuclear Astrophysics) collaboration between 2019 and 2024 have provided the most precise direct determinations to date of several key reaction rates in the NeNa cycle, specifically the ...

Precise Calculations of Nucleosynthesis Parameters and Electron Self-mass

, 2023
We study the effect of temperature on beta decay rate during primordial nucleosynthesis. Using thermal contributions to the renormalized mass of electron, we re-compute thermal effects to the nucleosynthesis parameters in the early universe in relation ...

Nucleosynthesis in Core-Collapse Supernovae

, 2019
Core-collapse supernovae (CCSNe) are one of the most important nucleosynthesis sites and they hold a key role in the evolution of galaxies. In the explosion, CCSNe eject freshly synthesized iron-group nuclei from explosive burning alongside of ...

Inhomogeneous primordial nucleosynthesis: Coupled nuclear reactions and hydrodynamic dissipation processes [PDF]

, 1994
We present a detailed numerical study of inhomogeneous big bang nucleosynthesis where, for the first time, nuclear reactions are coupled to all significant fluctuation dissipation processes.

Neutron-induced nucleosynthesis

, 1996
Neutron-induced nucleosynthesis plays an important role in astrophysical scenarios like in primordial nucleosynthesis in the early universe, in the s-process occurring in Red Giants, and in the cu-rich freeze-out and r-process taking place in supernovae ...

Recommendations for Monte Carlo nucleosynthesis sampling

, 2012
Context. Recent reaction rate evaluations include reaction rate uncertainties that have been determined in a statistically meaningful manner. Furthermore, reaction rate probability density distributions have been determined and published in the form of ...

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,
