Cannonballs in the context of Gamma Ray Bursts: Formation sites ?
Jan E. Staff, Christian Fendt, Rachid Ouyed
We investigate possible formation sites of the cannonballs (in the gamma ray bursts context) by calculating their physical parameters, such as density, magnetic field and temperatu…
3-Dimensional Simulations of the Reorganization of a Quark Star's Magnetic Field as Induced by the Meissner Effect
Rachid Ouyed, Brian Niebergal, Wolfgang Dobler +1
In a previous paper (Ouyed et al. 2004) we presented a new model for soft gamma-ray repeaters (SGR), based on the onset of colour superconductivity in quark stars. In this model, t…
Cooling of Quark Stars in the Color Superconductive Phase: Effect of Photons from Glueball decay
R. Ouyed, M. J. Hamp, S. C. Woodworth
The cooling history of a quark star in the color superconductive phase is investigated. Here we specifically focus on the 2-flavour color (2SC) phase where novel process of photon…
Fireballs from Quark Stars in the CFL Phase: Application to Gamma Ray Bursters
R. Ouyed, R. Rapp, C. Vogt
Recent studies of photon-generation mechanisms in the color-superconducting Color-Flavor Locked (CFL) phase of dense quark matter have found gamma-ray emissivities in excess of ~ 1…
GRMHD Simulations of Disk/Jet Systems: Application to the Inner Engines of Collapsars
Jean-Pierre De Villiers, Jan Staff, Rachid Ouyed
We have carried out 2D and 3D general relativistic magnetohydrodynamic simulations of jets launched self-consistently from accretion disks orbiting Kerr black holes and applied the…
