Thefireshellmodel and the“canonical GRBscenario

摘要：

The Swift observation of GRB 060614,as well as the catalog analysis by Norris and Bonnell 1,opened thedoor“on a new Gamma-Ray Bursts(GRBs)classification scheme that straddles both long and short bursts2．Within the“fireshellmodel for the Gamma-Ray Bursts (GRBs)we define a“canonical GRBlight curve with two sharply differentcomponents：the Proper-GRB(P-GRB),emitted when the optically thick fireshell of electron-positron plasma originatingthe phenomenon reaches transparency,and the afterglow,emitted due to the collision between the remaining optically thinfireshell and the CircumBurst Medium(CBM)．We here oufline our“canonical GRBscenario,Which implies three differentGRB classes：the“genuineshort GRBs,the“fakeor“disguisedshort GRBs and the other(so-called“long)GRBs．Wealso outline some implications for the theoretical interpretation of the Amati relation．
