Abstract EN
If a quark-nova occurs inside a collapsar, the interaction between the quark-nova ejecta (relativistic iron-rich chunks) and the collapsar envelope leads to features indicative of those observed in Gamma Ray Bursts.
The quark-nova ejecta collides with the stellar envelope creating an outward moving cap (Γ∼ 1–10) above the polar funnel.
Prompt gamma-ray burst emission from internal shocks in relativistic jets (following accretion onto the quark star) becomes visible after the cap becomes optically thin.
Model features include (i) precursor activity (optical, X-ray, γ-ray), (ii) prompt γ-ray emission, and (iii) afterglow emission.
We discuss SN-less long duration GRBs, short hard GRBs (including association and nonassociation with star forming regions), dark GRBs, the energetic X-ray flares detected in Swift GRBs, and the near-simultaneous optical and γ-ray prompt emission observed in GRBs in the context of our model.
