Collapsar Disk Outflows III: Detectable Neutrino and Gravitational Wave Signatures
Rodrigo Fernández, Silas Janke, Coleman Dean +1
We investigate the neutrino and gravitational wave (GW) signals from accretion disks formed during the failed collapse of a rotating massive star (a collapsar). Following black hol…

Collapsar disk outflows II: Heavy element production
Coleman Dean, Rodrigo Fernández
We investigate nucleosynthesis in the sub-relativistic outflows from black hole (BH) accretion disks formed in failed supernovae from rapidly-rotating Wolf-Rayet stars. These disks…

Collapsar disk outflows I: Viscous hydrodynamic evolution in axisymmetry
Coleman Dean, Rodrigo Fernández
We investigate mass ejection from accretion disks formed during the collapse of rapidly-rotating Wolf-Rayet stars. The neutrino-cooled, black hole (BH) accretion disk system that f…
