Central engines of Gamma Ray Bursts. Magnetic mechanism in the collapsar model

Understand

In this study we explore the magnetic mechanism of hypernovae and relativistic jets of long duration gamma ray bursts within the collapsar scenario.

• This is an extension of our earlier work [1].
• We track the collapse of massive rotating stars onto a rotating central black hole using axisymmetric general relativistic magnetohydrodynamic code that utilizes a realistic equation of state and takes into account the cooling associated with emission of neutrinos and the energy losses due to dissociation of nuclei.
• The neutrino heating is not included.
