Impact of a varying accelerated electron fraction ζ: spectral evolution. Time-resolved spectra are plotted for Case B assuming a varying parameter ζ during the propagation of internal shocks (see text). The corresponding light curves are shown in the right panel of Fig. 10. Each curve corresponds to a time interval of 0.25 s, starting with the bluest curve (0.5–0.75 s) and finishing with the reddest one (9.75–10 s). The time bin corresponding to the pulse maximum is indicated (1.5–1.75 s). The time-integrated spectrum is also plotted as a thick black line. A thin dashed line of photon index α = − 1 is indicated for comparison.
