Abstract
The analysis and classification of a sample of X-ray light curves of 64 long Gamma-ray bursts (GRB) observed by Swift/XRT without flaring activity reveals indeed similarities among different parts of the light curves. In this paper we focus on the shallow decays phases: we show that a spinning-down magnetar that powers the forward shock can quantitatively account for the shallow decay properties. In particular we demonstrate that this model can account for the plateau luminosity vs. end time anticorrelation found by Dainotti et al. (2008, 2010).
