Abstract

Long duration Gamma Ray Bursts (LGRB) are thought to originate from massive rotating stars and the interaction of their expanding jet will be affected by the structure of their circumburst medium. In this work we use rotating stellar models of massive stars to determine the state of circumbust material in various types of progenitor scenarios and we describe how this external matter can appear in GRB observations.
