Abstract

The role of hydrodynamic, magnetic internal angular momentum transport, binary mass, and angular momentum transfer, is investigated. Models that include magnetic fields generated by differential rotation are presented. The capability of magnetic torques to efficiently pump angular momentum into the cores of accreting stars is also investigated. It is observed that binary models without magnetic fields can reproduce stellar cores with a high enough specific angular momentum to produce a collapsar and a GRB.
