Compact objects, magnetic field and the effect in their structure and velocities |

Abstract |
Extreme magnetic fields are present in compact objects. We explain the effects of the magnetic field in the structure of these exotic objects and also in the translational velocities of Neutron stars. Regarding the structure of these stars, the anisotropy produced by the magnetic field in the pressures suggests the necessity of using structure equations that take into account the axial symmetry of the magnetized system. So, we propose a model that generalizes the Tolman-Oppenheimer-Volkoff equations for the magnetized case and discuss some preliminary results. Concerning the translational velocities of Neutron stars, we study the anisotropic neutrino emission from the core of neutron stars induced by the star’s magnetic field. we find that the anisotropic neutrino emission produces a rocket effect that contributes to the star’s kick velocity, which lies within the range of the observed values, reaching velocities of the order of ∼1000 km s−1 for magnetic fields between $10^{15}$ − $10^{18}$ G and radii of 20 to 5 km, respectively. |
