Neutrino Capture and r-Process Nucleosynthesis
We explore neutrino capture during r-process nucleosynthesis in neutrinodriven ejecta from nascent neutron stars. We focus on the interplay between charged-current weak interactions and element synthesis, and we delineate the important role of equilibrium nuclear dynamics. During the period of coexistence of free nucleons and light and/or heavy nuclei, electron neutrino capture inhibits the r-p...
متن کاملNeutrino-Driven Jets and Rapid-Process Nucleosynthesis
We have studied whether the jet in a collapse-driven supernova can be a key process for the rapid-process (r-process) nucleosynthesis. We have examined the features of a steady, subsonic, and rigidly rotating jet in which the centrifugal force is balanced by the magnetic force. As for the models in which the magnetic field is weak and angular velocity is small, we found that the r-process does ...
متن کاملNeutrino-nucleus interaction and supernova r-process nucleosynthesis
We discuss various neutrino-nucleus interactions in connection with the supernova rprocess nucleosynthesis, which possibly occurs in the neutrino-driven wind of a young neutron star. These interactions include νe and ν̄e absorptions on free nucleons, νe captures on neutron-rich nuclei, and neutral-current νμ(τ) and ν̄μ(τ) interactions with α-particles and neutron-rich nuclei. We describe how thes...
متن کاملSupernova SN1987A Bound on Neutrino Spectra for R-Process Nucleosynthesis
The neutrino driven wind during a core collapse supernova is an attractive site for r-process nucleosynthesis. The electron fraction Ye in the wind depends on observable neutrino energies and luminosities. The mean antineutrino energy is limited by supernova SN1987A data while lepton number conservation constrains the ratio of antineutrino to neutrino luminosities. If Ye, in the wind, is to be ...
متن کاملNeutrino-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 out that the effects would be especially pronounced for 8 isotopes that can be efficiently synthesized by the neutrino reactions following r-process freeze-out. We show that the observed abundances of the...
