Neutron capture on 130Sn during r-process freeze-out
J. Beun, J. C. Blackmon, W. R. Hix +3
We examine the role of neutron capture on 130Sn during r-process freeze-out in the neutrino-driven wind environment of the core-collapse supernova. We find that the global r-proces…
Fission Cycling in a Supernova r-process
J. Beun, G. C. McLaughlin, R. Surman +1
Recent halo star abundance observations exhibit an important feature of consequence to the r-process: the presence of a main r-process between the second and third peaks which is c…
Neutrinos, Fission Cycling, and the r-process
J. Beun, G. C. McLaughlin, R. Surman +1
It has long been suggested that fission cycling may play an important role in the r-process. Fission cycling can only occur in a very neutron rich environment. In traditional calcu…
Supernova Neutrinos: The Accretion Disk Scenario
G. C. McLaughlin, R. Surman
Neutrinos from core collapse supernovae can be emitted from a rapidly accreting disk surrounding a black hole, instead of the canonical proto-neutron star. For Galactic events, det…
Fission Cycling in Supernova Nucleosynthesis: Active-Sterile Neutrino Oscillations
J. Beun, G. C. McLaughlin, R. Surman +1
We investigate nucleosynthesis in the supernovae post-core bounce neutrino-driven wind environment in the presence of active-sterile neutrino transformation. We consider active-ste…
Nucleosynthesis in the Outflow from Gamma Ray Burst Accretion Disks
R. Surman, G. C. McLaughlin, W. R. Hix
We examine the nucleosynthesis products that are produced in the outflow from rapidly accreting disks. We find that the type of element synthesis varies dramatically with the degre…
