Abstract

The possibility to divide GRBs in different subclasses allow to understand better thephysics underlying their emission mechanisms and progenitors. The induced gravitationalcollapse scenario proposes a binary progenitor to explain the time-sequence in GRBs-SNe.We show the existence of a common behavior of the late decay of the X-ray afterglowemission of this subclass of GRBs, pointing to a common physical mechanism of their lateemission, consistent with the IGC picture.
