Slow and Fast Components in X-Ray light curves of GRBs. II: New Analysis
Abstract
Vetere et al. (2006) proposed that the light curves of some GRBs observed by the WFCs on board BeppoSAX are characterised by peaks superposed on a slowly evolving pedestal, which at high energy is less apparent. We described this behaviour with the presence of two components (slow and fast) having different time scales. The slow component, SC, is usually less pronounced in the 5-10 keV energy range and almost disappears at higher energies, whereas the residual fast component FC generally show a harder spectrum. In this contribution we present a new analysis of the SC and FC properties of the GRB 010222 and discuss on the possible presence of a genuine SC in the light curve of GRB 030329 observed by HETE.
