We present a simplified analysis using equations for the charge flow, which include ν_e capture, for the production of r-process nuclei in the context of the recent supernova hot bubble model. The role of ν_e capture in speeding up the charge flow, particularly at the closed neutron shells, is studied together with the β flow at freezeout and the effect of neutrino-induced neutron emission on the abundance pattern after freezeout. It is shown that a semiquantitative agreement with the gross… Expand
We examine the r-process in the neutrino-driven proto-neutron-star (PNS) wind of core-collapse supernovae in light of the recent findings of massive neutron stars in binaries as well as of anExpand
The r-, p-, and νp-Process
The processes discussed in this review are three of the four nucleosynthesis processes involved in producing heavy nuclei beyond Fe (not counting the rp-process in X-ray bursts). Opposite to theExpand
Nuclear structure studies at ISOLDE and their impact on the astrophysical r-process
The focus of the present review is the production of the heaviest elements in nature via the r-process. A correct understanding and modeling requires the knowledge of nuclear properties far fromExpand
Nuclear structure studies for the astrophysical r-process
Abstract The production of the heaviest elements in nature occurs via the r-process, i.e. a combination of rapid neutron captures, the inverse photodisintegrations, and slower β − -decays, β -delayedExpand
Isotopic r-process abundances produced by supernova explosions
The rapid neutron capture process (r-process) is one of the major nucleosynthesis processes responsible for the synthesis of heavy nuclei beyond iron. Isotopes beyond Fe are most exclusively formedExpand
Neutrino Fluence after r‐Process Freezeout and Abundances of Te Isotopes in Presolar Diamonds
Using the data of Richter, Ott, & Begemann on Te isotopes in diamond grains from a meteorite, we derive bounds on the neutrino fluence and the decay timescale of the neutrino flux relevant for theExpand
On the production of chemical elements beyond the iron peak
We discuss the possibility of elements heavier than iron being produced in the cooling central part of a low-mass supernova remnant in terms of a consistent kinetic model that incorporates reactionsExpand
The astrophysical r-process: A comparison of calculations following adiabatic expansion with classical calculations based on neutron densities and temperatures
The rapid neutron-capture process (r-process) encounters unstable nuclei far from β-stability. Therefore its observable features, like the abundances, witness (still uncertain) nuclear structure asExpand
Rapid neutron capture process in supernovae and chemical element formation
The rapid neutron capture process (r-process) is one of the major nucleosynthesis processes responsible for the synthesis of heavy nuclei beyond iron. Isotopes beyond Fe are most exclusively formedExpand
Nucleosynthesis in the early galaxy
Recent observations of r-process-enriched metal-poor star abundances reveal a nonuniform abundance pattern for elements -->Z ≤ 47. Based on noncorrelation trends between elemental abundances as aExpand


The alpha -Process and the r-Process
The paper explores the alpha-rich freeze-out for values of neutron excesses larger than previously treated, and reports the discovery of nuclear systematics that, for neutron excesses greater thanExpand
Neutrino-induced neutron spallation and supernova r -process nucleosynthesis
It is quite likely that the site of the r process is the hot, neutron-rich “bubble” that expands off a protoneutron star during a core-collapse supernova. The r process would then occur in an intenseExpand
Nucleosynthesis in Neutrino-Driven Winds. I. The Physical Conditions
During the first 20 s of its life, the enormous neutrino luminosity of a neutron star drives appreciable mass loss from its surface. Previous investigations have shown that this neutrino-driven windExpand
r-process nucleosynthesis in the high-entropy supernova bubble
We show that the high-temperature, high-entropy evacuated region outside the recent neutron star in a core-collapse supernova may be an ideal r-process site. In this high-entropy environment it isExpand
The r-process and neutrino-heated supernova ejecta
As a neutron star is formed by the collapse of the iron core of a massive star, its Kelvin-Helmholtz evolution is characterized by the release of gravitational binding energy as neutrinos. TheExpand
s-process nucleosynthesis-nuclear physics and the classical model
Among the various processes responsible for the formation of the heavy elements in stars, the slow neutron capture process (s-process) is distinguished by the fact that it involves mostly stableExpand
Neutrino Reactions on 4He and the r-Process
Neutrinos from a Kelvin-Helmholtz-cooling neutron star drive the winds in which the r-process of nucleosynthesis possibly occurs. The neutrinos establish the matter expansion rate, the entropy perExpand
Neutrino-induced nucleosynthesis and the site of the r process
If the r process occurs deep within a type II supernova, probably the most popular of the proposed sites, abundances of r-process elements may be altered by the intense neutrino flux. We point outExpand
