Clues to the nature of massive star explosions from GRB X-ray afterglows

Abstract

X-ray afterglows of long gamma-ray bursts (GRBs) provide some insights into the details of massive star explosions. Clues to the nature of the progenitors can be found from the "canonical" phases of X-ray afterglows, including the initial steeply falling phase seen in many X-ray afterglows, the flat "plateau" phase, and the X-ray flares. The data point to extended central engine activity lasting much longer than the duration of the prompt gamma-ray emission, possibly indicating that the stellar collapse is protracted by fall-back of material for many hours after the explosion.
