Nucleosynthesis in early supernova winds III: No significant contribution from neutron-rich pockets
R. D. Hoffman, J. Pruet, J. L. Fisker +3
Recent nucleosynthesis calculations of Type II supernovae using advanced neutrino transport determine that the early neutrino winds are proton-rich. However, a fraction of the ejec…
On the origin of the lightest Molybdenum isotopes
Jacob Lund Fisker, Robert D. Hoffman, Jason Pruet
We discuss implications of recent precision measurements for the Rh93 proton separation energy for the production of the lightest molybdenum isotopes in proton-rich type II superno…
Nucleosynthesis in Early Supernova Winds II: The Role of Neutrinos
J. Pruet, R. D. Hoffman, S. E. Woosley +2
One of the outstanding unsolved riddles of nuclear astrophysics is the origin of the so called ``p-process'' nuclei from A = 92 to 126. Both the lighter and heavier p-process nucle…
Nucleosynthesis in the Hot Convective Bubble in Core-Collapse Supernovae
J. Pruet, S. E. Woosley, R. Buras +2
As an explosion develops in the collapsed core of a massive star, neutrino emission drives convection in a hot bubble of radiation, nucleons, and pairs just outside a proto-neutron…
On the Contribution of Gamma Ray Bursts to the Galactic Inventory of Some Intermediate Mass Nuclei
Jason Pruet, Rebecca Surman, Gail C. McLaughlin
Light curves from a growing number of Gamma Ray Bursts (GRBs) indicate that GRBs copiously produce radioactive Ni moving outward at fractions of the speed of light. We calculate nu…
Nucleosynthesis in Outflows from the Inner Regions of Collapsars
Jason Pruet, Todd Thompson, R. D. Hoffman
We consider nucleosynthesis in outflows originating from the inner regions of viscous accretion disks formed after the collapse of a rotating massive star. We show that wind-like o…
