The evolution and explosion of massive Stars II: Explosive hydrodynamics and nucleosynthesis [PDF]

, 1995
The nucleosynthetic yield of isotopes lighter than A = 66 (zinc) is determined for a grid of stellar masses and metallicities including stars of 11, 12, 13, 15, 18, 19, 20, 22, 25, 30, 35, and 40 M{sub {circle_dot}} and metallicities Z = 0, 10{sup {minus}

GRB-SN CONNECTION: CENTRAL ENGINE OF LONG GRBs AND EXPLOSIVE NUCLEOSYNTHESIS

, 2011
I have developed two-dimensional general relativistic magnetohydrodynamic (GRMHD) code. I have performed numerical simulations of collapsars using these codes and realistic progenitor models.

Direct Measurement of 59Cu(p,α)56Ni Precludes a Strong NiCu Cycle in Type-I X-Ray Bursts

The Astrophysical Journal
Model-observation comparisons of type-I X-ray bursts (XRBs) can reveal the properties of accreting neutron star systems, including the neutron star compactness. XRBs are powered by nuclear burning, and a handful of reactions have been shown to impact the

Sensitivity study of explosive nucleosynthesis in type Ia supernovae: Modification of individual thermonuclear reaction rates [PDF]

, 2012
Background: Type Ia supernovae contribute significantly to the nucleosynthesis of many Fe-group and intermediate-mass elements. However, the robustness of nucleosynthesis obtained via models of this class of explosions has not been studied in depth ...

SPIRIT Solver: Accelerating r-process Nucleosynthesis with Sparse Preconditioning

The Astrophysical Journal Supplement Series
We introduce Sparse Matrix Preconditioner for Iterative Refinement and Inversion Toolkit (SPIRIT), a general-purpose sparse matrix solver with a novel preconditioner designed for the large, sparse, and ill-conditioned Jacobian systems that arise in r ...

Effects of Hoyle state de-excitation on νp–process nucleosynthesis and Galactic chemical evolution

Physics Letters B
The particle-induced hadronic de-excitation of the Hoyle state in 12C induced by inelastic scattering in a hot and dense plasma can enhance the triple-alpha reaction rate.

Shell Evolutions and Nuclear Forces

EPJ Web of Conferences, 2014
During the last 30 years, and more specifically during the last 10 years, many experiments have been carried out worldwide using different techniques to study the shell evolution of nuclei far from stability.
