For short gamma-ray bursts (GRBs), double neutron star (NS) mergers are traditionally adopted as progenitors. We propose a classification of short bursts into two sub-classes: short gamma-ray flashes (S-GRFs) with isotropic energy Eiso ≲ 1052 erg and rest-frame spectral peak energy Ep,i ≲ 2 MeV, when the merger leads to a very massive NS (MNS),...
