Neutrino scattering in strong magnetic fields∗
Neutrino interactions in strong magnetic fields have gained a lot of attention because of the problem of neutrino emission from a proto-neutron star. It has been argued that a small asymmetry in the neutrino emission can explain the high peculiar velocities of pulsars. Based on earlier work[1] on neutrino dispersion relations in an external magnetic field, it has been shown[2] that neutrino osc...
متن کاملNeutrino Processes in Strong Magnetic Fields
The processes νe +n ⇋ e− + p and ν̄e + p ⇋ e +n provide the dominant mechanisms for heating and cooling the material below the stalled shock in a core-collapse supernova. We summarize the major effects of strong magnetic fields on the rates of the above reactions and illustrate these effects with a simple supernova model. Due to parity violation of weak interaction the heating rates are asymmetr...

متن کاملNeutron star composition in strong magnetic fields
We study the problem of neutron star composition in the presence of a strong magnetic field. The effects of the anomalous magnetic moments of both nucleons and electrons are investigated in relativistic mean field calculations for a β-equilibrium system. Since neutrons are fully spin polarized in a large field, generally speaking, the proton fraction can never exceed the field free case. An ext...
متن کاملThe Equation of State of Neutron-star Matter in Strong Magnetic Fields
We study the effects of very strong magnetic fields on the equation of state (EOS) in multicomponent, interacting matter by developing a covariant description for the inclusion of the anomalous magnetic moments of nucleons. For the description of neutron star matter, we employ a field-theoretical approach which permits the study of several models which differ in their behavior at high density. ...
