Scientific paper

Using Gadget 2 to model the collapse and accretion of polytropic envelopes with different initial angular momentum onto a BH, we observed the formation of an accretion disk due to rotation. We also tested the accretion of a non rotating polytropic envelope onto a BH using a Paczynski-Wiita potential to account for some relativistic effects on the gas. These series of tests will help develop the necessary modifications to Gadget 2 in the context of the collapsar model for GRBs.
