GRB1 |
Theoretical interpretation of the luminosity and spectral properties of GRB 980425 |
GRB 980425 is one of the most important GRBs observed by BeppoSAX. First of all it is the neares GRB ever detected, with the lowest luminosity. Moreover it is the first manifest case of an association between GRBs and Supernovae. The aim of this talk is to show how all its peculiarities find, without any new assuption, a simple explanation in our model. We reproduced the light curves in all the BeppoSAX energy bands as well as the time-integrated photon number spectrum in the prompt phase. Also, a possible interpretation of the GRB-SN connection will be outlined. |

GRB970228 as a prototype for Short GRBs with afterglow. |
GRB970228 is analyzed as a prototype to understand the relative role of the short GRBs and their associated afterglows, recently observed by Swift and HETE-II. Detailed theoretical computation of the GRB970228 light curves in selected energy bands as well as of the instantaneous and time-integrated spectra are presented and compared and contrasted with observational BeppoSAX data. |
