  • Jet powered by fallback accretion into a black hole of 3-5 solar masses. The inital spherically symmetric explosion had 0.255 x 1051 ergs and failed to unbind approximately 5.8 solar masses of the core which fell back in a few hundred seconds. 0.1% of the fallback accretion rest mass energy was injected through the inner boundary at 10,000 km with opening angle 10 degrees, internal pressure of half the ram pressure and velocity 1/3 the speed of light. Shown at t=9 s, 27 s and 68 s:
