Nucleosynthesis in core-collapse supernova explosions triggered by a quark-hadron phase transition
(2012-10-10)
We explore heavy-element nucleosynthesis in the explosion of massive stars that are triggered by a quark-hadron phase transition during the early post-bounce phase of core-collapse supernovae. The present study is based ...
The path to improved reaction rates for astrophysics
(2011-05)
This review focuses on nuclear reactions in astrophysics and, more specifically, on reactions with light ions (nucleons and alpha particles) proceeding via the strong interaction. It is intended to present the basic ...
Charged-particle and neutron-capture processes in the high-entropy wind of core-collapse supernovae
(2010-04-01)
The astrophysical site of the r-process is still uncertain, and a full exploration of the systematics of this process in terms of its dependence on nuclear properties from stability to the neutron drip-line within realistic ...
Neutron-induced astrophysical reaction rates for translead nuclei
(2010-04)
Neutron-induced reaction rates, including fission and neutron capture, are calculated in the temperature range 10(8)
Crucial inputs to nucleosynthesis calculations
(2008-01)
The first part of the paper discusses nuclear properties relevant to predict compound reactions. The second part addresses direct reactions with special emphasis on direct neutron capture.
Production of intermediate-mass and heavy nuclei
(Elsevier, 2007)
Nucleosynthesis is the science related to all astrophysical processes which are responsible for the abundances of the elements and their isotopes in the universe. The astrophysical sites are the big bang and stellar objects. ...
Nuclear physics : A key ingredient in astrophysical modeling
(2005-04-18)
Nuclear physics is a basic ingredient in a large number of energetic astrophysical environments which are characterized by sufficient temperatures and densities to permit scattering events among particles, leading to nuclear ...
Nuclear data needs for the study of nucleosynthesis in massive stars
(2003-05-05)
The critical nuclear physics needed to calculate the evolution of and nucleosynthesis in massive stars is reviewed with emphasis on the uncertainties. Some reaction rates - the most important and uncertain still being C-12 ...
Nucleosynthesis in supernovae
(Astronomical Society of the Pacific, 2002)
The evolution of gas abundances in galaxies and the enrichment of heavy elements as a function of space and time reflects the history of star formation and the lifetimes of the diverse contributing stellar objects. Supernovae ...
Nucleosynthesis and stellar evolution
(2002)
Two of the basic building blocks of galaxies are stars and the interstellar medium. The evolution of the abundance composition in the latter and especially the enrichment of heavy elements as a function of space and time ...
