Models for the circumstellar medium of long gamma-ray burst progenitor candidates

A. J. van Marle, N. Langer, A. Achterberg +1

We present hydrodynamical models of circumstellar medium (CSM) of long gamma-ray burst (GRB) progenitor candidates. These are massive stars that have lost a large amount of mass in…

Forming a constant density medium close to long gamma-ray bursts

A. J. van Marle, N. Langer, A. Achterberg +1

The progenitor stars of long Gamma-Ray Bursts (GRBs) are thought to be Wolf-Rayet stars, which generate a massive and energetic wind. Nevertheless, about 25 percent of all GRB afte…
