摘要: The two-component emission model to explain the plateau phase of X-ray afterglows gamma-ray bursts (GRBs) is proposed. One component, which responsible for and subsequent normal decay afterglow, prior via outflow ejected from central engine before main burst. other outflow, causes prompt GRB initial steep afterglow. In this model, transition an artifact choice zero time. For events with distinct phase, active 103-104 s launch outflow. According a in and/or optical bands possibly seen, will be tested by near-future instruments such as Monitor All-sky Image (MAXI), WIDe-field telescope Early Timing (WIDGET), so on.
