We propose a possible new mechanism for a strong and stable magnetic field of compact stars due to an instability in the presence of a chirality imbalance of electrons—the chiral plasma instability. A large chirality imbalance of electrons inevitably occurs associated with the parity-violating weak process during core collapse of supernovae. We estimate the magnetic field due to this instabilit...

We use numerical MHD to look at the stability of a possible poloidal field in neutron stars (Flowers & Ruderman 1977), and follow its unstable evolution, which leads to the complete decay of the field. We then model a neutron star after the formation of a solid crust of high conductivity. As the initial magnetic field we use the stable ‘twisted torus’ field which was the result of our earlier w...

The standard model for a short duration Gamma-Ray Burst (GRB) involves the merger of a neutron star binary system, resulting in a black hole which accretes for a brief period of time. However, some of the short-duration GRBs observed by the Swift satellite show features in their light curves which are difficult to explain in this model. As an alternative, we examine the light curves of the Swif...

Abstract We propose that chirally asymmetric plasma can be produced in the gap regions of magnetospheres pulsars and black holes. show that, case supermassive holes situated active galactic nuclei, chiral charge density chemical potential are very small unlikely to have any observable effects. In contrast, asymmetry magnetars substantial. It trigger instability turn, lead phenomena magnetars. p...
