title: The circumstellar environment of rotating Wolf-Rayet Stars and the implications for GRB afterglows.
abstract: If Wolf-Rayet stars are the progenitors of gamma-ray bursts (GRBs), they must rotate rapidly to produce the GRB. This rotation may affect their stellar-wind bubbles and possibly explain why so many GRB afterglows occur in a constant density medium.
