Long-duration GRB 211211A that lacks a supernova emission even down to very stringent limits at such a low redshift z = 0 . 076 and associate with kilonova emission, suggest that its physical origin is from binary compact stars merger. By re-analyzing its data observed with the GBM on board Fermi mission, we find that both time-integrated and time-resolved spectra can be fitted well by using Band plus blackbody (Band+BB) model in the prompt emission. The bulk Lorentz factors (Γ ph ) of the outflow…
