A semi-analytical solution to the forward–reverse shock hydrodynamics of the gamma-ray burst afterglow
ABSTRACT We extend the standard model of forward–reverse shock (FS–RS) for gamma-ray burst (GRB) afterglow to more general cases. On one hand, we derive the analytical solution to the hydrodynamics of the shocks in two limiting cases, i.e. an ultrarelativistic reverse shock case and a Newtonian reverse shock case. Based …
