Overall Evolution of Realistic Gamma-ray Burst Remnant and Its Afterglow

  • 25 June 1999
Abstract
Conventional dynamic model of gamma-ray burst remnants is found incorrect for adiabatic blastwaves during the non-relativistic phase. We have derived a new model, which is shown to be correct for both radiative and adiabatic blastwaves, and during both ultra-relativistic and non-relativistic phase. Our model also takes the evolution of the radiative efficiency into account. The importance of the transition from the ultra-relativistic phase to the non-relativistic phase is stressed.
