A three stage model for the inner engine of GRBs: Prompt emission and early afterglow
Jan Staff, Brian Niebergal, Rachid Ouyed
We describe a model within the ``Quark-nova'' scenario to interpret the recent observations of early X-ray afterglows of long Gamma-Ray Bursts (GRB) with the Swift satellite. This…
Gamma Ray Burst engine activity within the quark nova scenario: Prompt emission, X-ray Plateau, and sharp drop-off
Jan Staff, Brian Niebergal, Rachid Ouyed
We present a three-stage model for a long GRB inner engine to explain the prompt gamma ray emission, and interpret recent Swift satellite observations of early X-ray afterglow plat…
SGRs and AXPs proposed as ancestors of the Magnificent seven
Brian Niebergal, Rachid Ouyed, Denis Leahy
The recently suggested correlation between the surface temperature and the magnetic field in isolated neutron stars does not seem to work well for SGRs, AXPs and X-ray dim isolated…
Fall-back crust around a quark-nova compact remnant II: The degenerate torus case with applications to AXPs
Rachid Ouyed, Denis Leahy, Brian Niebergal
In the first paper of this series we explored the case where a quark-nova ejecta forms a degenerate shell, supported by the star's magnetic field. Herein, we consider the case wher…
Magnetic Field Decay and Period Evolution of Anomalous X-Ray Pulsars in the Context of Quark Stars
Brian Niebergal, Rachid Ouyed, Denis Leahy
We discuss a model wherein soft gamma-ray repeaters (SGRs), anomalous X-ray pulsars (AXPs), and radio quiet isolated neutron stars (RQINSs) are all compact objects exhibiting super…
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…
