Key parameters and mass fractions of nuclides (selected from the top 50 species) produced in collapsar accretions for cases A1-3 and B1-3.
Final mass fractions of explosive nucleosynthesis in the outflows associated with GRBs at r = 3rsch for cases A1-3 and B1-3.
As Table 2, but for cases A1-3 and B1-3 at r = 10rsch.
As Table 2, but for cases A1-3 and B1-3 at r = 20rsch.
As Table 2, but for cases A1-3 and B1-3 at r = 30rsch.
As Table 2, but for cases A1-3 and B1-3 at r = 40rsch.
As Table 2, but for cases A1-3 and B1-3 at r = 50rsch.
Total yields after radioactive decays in the final step tf for 1 M⊙ matter ejected from outflows associated with GRBs.

Fig. 3
Explosive nucleosynthesis in the outflow region associated with GRB for case A1 at r = 3rsch (case A1r = 3). The radioactive decays have been taken into account within the dynamic process [ t0,tf), but did not include the final step (tf), which can prevent some decayed species, as shown in this picture, from precipitously dropping to zero in the final step tf. |

Fig. 4
As Fig. 3, but for case A1 at r = 50rsch (case A1r = 50). It only shows the long (relative) half-life species (τ0.5> 1 day) by considering the timing of observations; the species with half-lives of τ0.5 ≤ 1 day are not plotted. The final abundances of nuclides as shown in this figure (selected from Table 7) exceed 10-11. |

Fig. 5
Five up-species abundance increase when the value of collapsar accretion rate Ṁ increases in panels a)−c) in the left column and in panels d)−f) in the right column. The other five down-species abundances decrease as Ṁ increases. The abscissa is scaled in the value of Ṁ. In a same panel, the same colors denote the same chemical species. |
