Aims: We investigate the behavior of the frequency-centered light curves expected within the standard model of gamma ray bursts, allowing the maximum electron energy (γmax) to be a free parameter that may take low values.
Methods: We solve the spatially averaged kinetic equations that describe the simultaneous evolution of particles and photons, obtaining the multi-wavelength spectra as a function of time. From these we construct the frequency-centered light curves with an emphasis on the X-ray and optical bands.
Results: We show that in cases where γmax takes low values, the produced X-ray light curves show a plateau as the synchrotron component gives its place to the synchrotron self-Compton one in the X-ray band.}, keywords = {acceleration of particles, Astrophysics - High Energy Astrophysical Phenomena, gamma-rays: general, radiation mechanisms: non-thermal}, isbn = {0004-6361}, url = {https://ui.adsabs.harvard.edu/abs/2011A\&A...531A..76P}, author = {Petropoulou, M. and Mastichiadis, A. and Piran, T.} }
