Abstract

Observational evidence suggests long-duration, collapsar-type gamma-ray bursts (GRBs) may have been more common in the early universe. These events are thought to be powered by accretion disks around black holes (AD-BHs). While GRBs require AD-BHs, not all AD-BHs will power bursts and therefore their formation will be more common than GRBs themselves. Outflows from AD-BHs may therefore be important contributors to the nuclear abundances in the oldest stars, particularly for rare species or those not uniformly observed. Here we consider the nucleosynthesis in this environment starting with relativistic disk models of Kerr black holes and following the element synthesis in a parameterized outflow. We present nucleosynthesis results from a range of AD-BH models.
