抄録

We have performed 2.5-dimensional general relativistic magnetohydrodynamic (MHD) simulations of collapsars as a model of gamma ray bursts (GRBs). This simulation showed the formation of a disk-like structure and the generation of a mildly relativistic jet (～0.3c). We have found the jet is accelerated by the magnetic pressure and the centrifugal force and is collimated by the pinching force of the toroidal magnetic field amplified by the rotation.
