Abstract
The Swift observation of GRB 060614, as well as the catalog analysis by Norris and Bonnell [1], opened the door "on a new Gamma-Ray Bursts (GRBs) classification scheme that straddles both long and short bursts" [2]. Within the "fireshell" model for the Gamma-Ray Bursts (GRBs) we define a "canonical GRB" light curve with two sharply different components: the Proper-GRB (P-GRB), emitted when the optically thick fireshell of electron-positron plasma originating the phenomenon reaches transparency, and the afterglow, emitted due to the collision between the remaining optically thin fireshell and the CircumBurst Medium (CBM). We here outline our "canonical GRB" scenario, which implies three different GRB classes: the "genuine" short GRBs, the "fake" or "disguised" short GRBs and the other (so-called "long") GRBs. We also outline some implications for the theoretical interpretation of the Amati relation. © 2008 American Institute of Physics.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
