Is GRB 050904 a super-long burst?

Abstract
By considering synchrotron radiative process in the internal shock model and assuming that all internal shocks are nearly equally energetic, we analyze the gamma-ray burst (GRB) emission at different radii corresponding to different observed times. We apply this model to GRB 050904 and find that our analytical results can provide a natural explanation for the multi-band observations of GRB 050904. This suggests that the X-ray flare emission and the optical emission of this burst could have originated from internal shocks being due to collisions among nearly-equally-energetic shells ejected from the central engine. Thus GRB 050904 appears to be a burst with super-long central engine activity.
