Nucleosynthesis: Stellar and Solar Abundances and Atomic Data [PDF]

, 2006
Abundance observations indicate the presence of often surprisingly large amounts of neutron capture (i.e., s- and r-process) elements in old Galactic halo and globular cluster stars.

Nucleosynthesis by N-14 depletion during shell He burning in massive stars

, 1987
New computations of He shell nucleosynthesis occurring during both radiative and convective phases are presented for stars in the range 8 - 25 M_sun;, taking in account the recent changes proposed for many cross sections.

Production of Heavy α-Elements and 44Ti in Cas A: Comparison to Abundances from 1D Core-collapse Supernova Models and Evidence for Carbon–Oxygen Shell Mergers

The Astrophysical Journal Letters
The merger between the carbon (C) and oxygen (O) shells hours to days before the collapse of a massive star significantly changes its nucleosynthesis, which is reflected in the elemental ratios observed in supernova remnants (SNRs).

Constraining Neutron-Capture Nucleosynthesis from Surface Chemical Composition of Chemically Peculiar Stars: The Puzzling Case of HE 1005-1439

Galaxies
The chemical composition of stellar atmospheres provides a valuable window into the complex processes of stellar nucleosynthesis. Among chemically peculiar cool stars, many objects are the products of mass transfer in binary systems, including most ...

Nucleosynthesis and Nucleo-Cosmochronology

, 2004
I discuss a few selected topics on nucleosynthesis and nucleo-cosmochronology in faint, if not totally illusory, hopes of helping to gain a clear perspective of the future astronuclear physics.

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 ...
