英文摘要 | Stellar-mass black holes (BHs) surrounded by neutrino-dominated accretion flows (NDAFs) are plausible sources of power. for. gamma-ray bursts (GRBs) via neutrino. emission and their annihilation. The progenitors of short-duration GRBs (SGRBs) are generally considered to be compact binary. mergers. According to the simulation results, the disk mass of the NDAF is limited after merger events. We can estimate such disk masses. using the current SGRB observational data and fireball model. The results show that the disk mass of a certain SGRB mainly depends on its output energy, jet opening angle, and central BH characteristics. Even for the extreme BH parameters, some SGRBs require massive disks, which approach or exceed the limits in simulations. We suggest that there may exist alternative MHD processes or mechanisms that increase the neutrino emission to produce SGRBs with reasonable BH parameters and disk masses. |
