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 ...

New Results on Nucleosynthesis in Massive Stars; Nuclear Data Needs for Nucleosynthesis

, 2001
We review the current status of the nuclear reaction rates needed to study nucleosynthesis in massive stars. Results for the calculated nucleosynthesis of all stable species from Hydrogen to Bismuth in a completely evolved 25 M{sub {circle_dot}} star of ...

Universality and variability of the heavy r-process element abundance pattern from a nonequilibrium approach

Frontiers in Astronomy and Space Sciences
A striking feature in the observed chemical composition of the majority of stars is the universality of the relative abundances of the heavy elements, although some outliers exist.

From (p)reheating to nucleosynthesis

, 2002
This paper gives a brief qualitative description of the possible evolution of the early universe between the end of an inflationary epoch and the end of big-bang nucleosynthesis.

Neutrino-driven winds and nucleosynthesis [PDF]

, 2008
Baryonic outflows from proto-neutron stars formed in core-collapse supernova explosions are one of the possible scenarios for the production of heavy elements via the r-process.

Violent mergers revisited: The origin of the fastest stars in the Galaxy

Astronomy & Astrophysics
Binary systems of two carbon-oxygen white dwarfs are one of the most promising candidates for the progenitor systems of Type Ia supernovae. Violent mergers, where the primary white dwarf ignites when the secondary white dwarf smashes into it while being ...
