Abstract
In this work we present the results of the analysis of GRB 101023 in the fireshell scenario. Its redshift is not known, so we attempted to infer it from the Amati Relation, obtaining z = 0.9. Its light curve presents a double emission, which makes it very similar to the already studied GRB 090618. We called each part Episode 1 and Episode 2. We performed a time-resolved spectral analysis with RMFIT using different spectral models, and fitted the light curve with a numerical code integrating the fireshell equations of motion. We used Fermi GBM data to build the light curve, in particular the second NaI detector, in the range (8.5–1000 keV). We considered different hypotheses regarding which part of the light curve could be the GRB and performed the analysis of all of them. We noticed a great variation of the temperature with time in the first episode, as well as almost no variation of the progenitor radius. We found that the first emission does not match the requirements for a GRB, while the second part perfectly agrees with being a canonical GRB, with a P-GRB lasting 4 s.
