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 degree of neutrino trapping in the disk and therefore the accretion rate of the disk. Disks with relatively high accretion rates such as {dot M} = 10 M {circle_dot} s{sup -1} can produce very neutron-rich nuclei that are found in the r-process. Disks with more moderate accretion rates can produce copious amounts of nickel… Expand
We investigate nucleosynthesis inside the outflows from gamma-ray burst (GRB) accretion disks formed by the Type II collapsars. In these collapsars, massive stars undergo core collapse to form aExpand
Nucleosynthesis in the accretion disks of Type II collapsars
We investigate nucleosynthesis inside the gamma-ray burst (GRB) accretion disks formed by the Type II collapsars. In these collapsars, the core collapse of massive stars first leads to the formationExpand
Nucleosynthesis of elements in gamma-ray burst engines
We consider the gamma ray burst (GRB) central engine that is powered by the collapse of a massive rotating star or compact binary merger. The engine is a hot and dense accretion disk, which isExpand
Nucleosynthesis of Nickel-56 from Gamma-Ray Burst Accretion Disks
We examine the prospects for producing Nickel-56 from black hole accretion disks, by examining a range of steady state disk models. We focus on relatively slowly accreting disks in the range of 0.05Expand
Nucleosynthesis in Supernovae
We present the status and open problems of nucleosynthesis in supernova explosions of both types, responsible for the production of the intermediate mass, Fe-group and heavier elements (with theExpand

Short gamma-ray bursts require a rotating black hole, surrounded by a magnetized relativistic accretion disk, such as the one formed by coalescing binary neutron stars or neutron star - black holeExpand
Production of Nickel-56 in black hole-neutron star merger accretion disk outflows
The likely outcome of a compact object merger event is a central black hole surrounded by a rapidly accreting torus of debris. This disk of debris is a rich source of element synthesis, the outcomeExpand
r-Process Nucleosynthesis in Hot Accretion Disk Flows from Black Hole - Neutron Star Mergers
We consider hot accretion disk outflows from black hole-neutron star mergers in the context of the nucleosynthesis they produce. We begin with a three-dimensional numerical model of a blackExpand
Nucleosynthesis and Evolution of Massive Metal-Free Stars
The evolution and explosion of metal-free stars with masses 10-100 M ? are followed, and their nucleosynthetic yields, light curves, and remnant masses determined. Such stars would have been theExpand
The role of neutrinos in r-process nucleosynthesis in supernovae and gamma-ray bursts
The exact astrophysical site of the r-process is uncertain, but the likely candidates—supernovae and compact merger events—are environments with high neutrino fluxes. Here we examine the role ofExpand


Nucleosynthesis in Gamma-Ray Burst Accretion Disks
We follow the nuclear reactions that occur in the accretion disks of stellar-mass black holes that are accret- ing at a very high rate, 0.01-1 Ms � 1 , as is realized in many current models forExpand
Nucleosynthesis inside an Accretion Disk and Disk Winds Related to Gamma-Ray Bursts
We investigate nucleosynthesis inside both a gamma-ray burst accretion disk and a wind launched from an inner region of the disk using one-dimensional models of the disk and wind. Far from a centralExpand
Neutrino Interactions in the Outflow from Gamma-Ray Burst Accretion Disks
We examine the composition of matter as it flows away from gamma-ray burst (GRB) accretion disks in order to determine what sort of nucleosynthesis may occur. Since there is a large flux of neutrinosExpand
Neutrinos and Nucleosynthesis in Gamma-Ray Burst Accretion Disks
We calculate the nuclear composition of matter in accretion disks surrounding stellar mass black holes as are thought to accompany gamma-ray bursts (GRBs). We follow a mass element in the accretionExpand
Prospects for obtaining an r process from Gamma Ray Burst Disk Winds
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 sufficiently high thatExpand
Bipolar Supernova Explosions: Nucleosynthesis and Implications for Abundances in Extremely Metal-Poor Stars
Hydrodynamics and explosive nucleosynthesis in bipolar supernova explosions are examined to account for some peculiar properties of hypernovae as well as peculiar abundance patterns of metal-poorExpand
Nucleosynthesis in the hot convective bubble in core-collapse supernovae
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 star. ShortlyExpand
A variety of current models of gamma-ray bursts (GRBs) suggest a common engine: a black hole of several solar masses accreting matter from a disk at a rate of 0.01 to 10 M☉ s-1. Using a numericalExpand
