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…
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…
Prospects for obtaining an r-process from Gamma Ray Burst Disk Winds
G. C. McLaughlin, R. Surman
We discuss the possibility that r-process nucleosynthesis may occur in the winds from gamma ray burst accretion disks. This can happen if the temperature of the disk is sufficientl…
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…
