| Abstract: |
We explore our speculation that the progenitors of gamma-ray bursts are born and located in the centers of massive low-metallicity protoglobular clusters. A binary merger of the two most massive stars in the mass segregated dense proto-cluster core may lead to a rapidly rotating object exploding as a hypernova, leaving a collapsar remnant (cf. Bally and Zinnecker 2005). The particular role of low metallicity is addressed. |
