Quark-Nova Explosion inside a Collapsar: Application to Gamma Ray Bursts

Figure 3

Estimated fluence of the precursor in the thick envelope case (from (2). The four curves are for ejecta masses from 10⁻⁵𝑀_⊙ to 10⁻²𝑀_⊙ from left to right (all with a QN ejecta with Γ_𝑖=10). The peak fluence occurs at 𝑚_ejecta=2𝑚_env with a value of about 6% of 𝑚_ejecta𝑐².
