The Supercritical Pile Model for GRBs
Abstract
We present the spectral and temporal radiative signatures expected within the Supercritical Pile model of Gamma Ray Bursts GRBs This model is motivated by the need for a process that provides the dissipation necessary in GRBs and presents a well defined scheme for converting the energy stored in the relativistic protons of the Relativistic Blast Waves RBW associated with GRBs into radiation at the same time it leads to spectra which exhibit a peak in the nu F nu distribution of the burst at an energy E p sim 1 MeV in the observer s frame in agreement with observation and largely independent of the Lorentz factor Gamma of the associated relativistic outflow Furthermore this scheme does not require but does not preclude acceleration of particles at the shock other than that provided by the isotropization of the flow bulk kinetic energy on the RBW frame In the present paper we show a detailed evolution of the spectra as the RBW expands into a constant density environment and discuss ways of connecting the prompt emission with the afterglow within the framework of this model
