Amplification of neutron star magnetic fields by thermoelectric effects. II - Linear approximation

Abstract: In the first paper (Geppert & Wiebicke 1990), a formalism for investigating the influence of thermoelectric effects on the magnetic field in the envelope of neutron stars, based on the simultaneous solution of the time-dependent nonlinear heat transport equation and induction equation, was presented. Here, the linear approximation is considered, which is justified for moderate magnetic field strengths. Numerically calculated growth and decay rates of magnetic field components with different multipolarities n are presented
