Quark-Nova Explosion inside a Collapsar: Application to Gamma Ray Bursts
Outline of the initial phases for GRBs from Quark-Novae (QN). Stage 1. A newly formed neutron star with expanding ejecta and SN shock wave, as well as the stationary WR stellar envelope is also shown. Angular momentum of the progenitor results in low-density polar funnels. Stage 2. An explosive neutron star to quark star conversion (i.e., Quark-Nova) occurs producing the QN ejecta. The QN ejecta can then propagate freely through the funnel, while in other directions it will overtake the SN ejecta. Stage 3. The QN ejecta along the funnel interacts with the WR stellar envelope, while the collision of the SN ejecta and QN ejecta leads to an energized outgoing ejecta (suggestive of a hypernova).
