Ignition of Weak Interactions and r-process Outflows in Supercollapsar Accretion Disks

The collapse of rotating massive (∼10 M _⊙ ) stars resulting in hyperaccreting black holes (BHs; “collapsars”) is a leading model for the central engines of long-duration gamma-ray bursts (GRBs) and a promising source of rapid neutron-capture ( r -process) elements. R -process nucleosynthesis in dis...
