Abstract:

The shock model of gamma-ray bursts (GRBs) has two free parameters: epsilon(B) and epsilon(e). It has been shown that epsilon(B) should range between few x 10(-3) and few x 10(-4). However, how to calculate the value of ee has remained an outstanding theoretical problem for over a decade. Here, we demonstrate that the Weibel theory inevitably predicts that epsilon(e) similar or equal to root epsilon(B). The GRB afterglow data fully agree with this theoretical prediction. Our result explains why the electrons are close to equipartition in GRBs. This epsilon(e) epsilon(B) relation can potentially be used to reduce the number of free parameters in afterglow models.
