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 black hole-neutron star merger and calculate the neutrino and antineutrino fluxes emitted from the resulting accretion disk. We then follow the element synthesis in material outflowing the disk along parameterized trajectories. We find that at least a weak r-process is produced, and in some cases a main r-process…

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 outcome
Production of the entire range of r-process nuclides by black hole accretion disc outflows from neutron star mergers
We consider $r$-process nucleosynthesis in outflows from black hole accretion discs formed in double neutron star and neutron star -- black hole mergers. These outflows, powered by angular momentum
Delayed outflows from black hole accretion tori following neutron star binary coalescence
Expulsion of neutron-rich matter following the merger of neutron star (NS) binaries is crucial to the radioactively-powered electromagnetic counterparts of these events and to their relevance as
Outflows from accretion discs formed in neutron star mergers: effect of black hole spin
The accretion disk that forms after a neutron star merger is a source of neutron-rich ejecta. The ejected material contributes to a radioactively-powered electromagnetic transient, with properties
Signatures of hypermassive neutron star lifetimes on r-process nucleosynthesis in the disc ejecta from neutron star mergers
We investigate the nucleosynthesis of heavy elements in the winds ejected by accretion discs formed in neutron star mergers. We compute the element formation in disc outflows from hypermassive
The r-process in the neutrino-driven wind from a black-hole torus
We examine r-process nucleosynthesis in the neutrino-driven wind from the thick accretion disk (or 'torus') around a black hole. Such systems are expected as remnants of binary neutron star or
Black hole (BH) accretion disks have been proposed as good candidates for a range of interesting nucleosynthesis, including the r-process. The presence of the BH influences the neutrino fluxes and
The influence of neutrinos on the nucleosynthesis of accretion disc outflows
We present a short review of recent progress on the influence of neutrinos on the nucleosynthesis from black hole accretion disc outflows. Discs that form from the end of life of rapidly rotating
Neutron Star Mergers and Nucleosynthesis of Heavy Elements
The existence of neutron star mergers has been supported since the discovery of the binary pulsar and the observation of its orbital energy loss, consistent with General Relativity. They are
Nucleosynthesis in core-collapse supernova explosions triggered by a quark-hadron phase transition
We explore heavy element nucleosynthesis in the explosion of massive stars which are triggered by a quark-hadron phase transition during the early post bounce phase of core-collapse supernovae. The


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 accretion
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 windlike outflows driven by
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 neutrinos
r-Process in Neutron Star Mergers.
Sufficient material is ejected to explain the amount of r-process nuclei in the Galaxy by decompression of neutron star material, and the calculated abundances fit the observed solar r-pattern excellently for nuclei that include and are heavier than the A approximately 130 peak.
Black Hole-Neutron Star Mergers as Central Engines of Gamma-Ray Bursts.
Hydrodynamic simulations of the merger of stellar mass black hole-neutron star binaries are compared with mergers of binary neutron stars and the use of a physical nuclear equation of state allows us to include the effects of neutrino emission.
The Lowest-Mass Stellar Black Holes: Catastrophic Death of Neutron Stars in Gamma-Ray Bursts
Mergers of double neutron stars are considered the most likely progenitors for short gamma-ray bursts. Indeed, such a merger can produce a black hole with a transient accreting torus of nuclear
Neutrino-induced nucleosynthesis of A>64 nuclei: the nu p process.
In this process, antineutrino absorptions in the proton-rich environment produce neutrons that are immediately captured by neutron-deficient nuclei, allowing for the nucleosynthesis of nuclei with mass numbers A>64, , making this process a possible candidate to explain the origin of the solar abundances of (92,94)Mo and (96,98)Ru.
Nucleosynthesis in the Outflow from Gamma-Ray Burst Accretion Disks
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
