Query: Stationary Electromagnetic Fields of a Slowly Rotating Magnetized
  Neutron Star in General Relativity   Following the general formalism presented by Rezzolla, Ahmedov and Miller
(MNRAS, 322, 723 2001), we here derive analytic solutions of the
electromagnetic fields equations in the internal and external background
spacetime of a slowly rotating highly conducting magnetized neutron star. The
star is assumed to be isolated and in vacuum, with a dipolar magnetic field not
aligned with the axis of rotation. Our results indicate that the
electromagnetic fields of a slowly rotating neutron star are modified by
general relativistic effects arising from both the monopolar and the dipolar
parts of the gravitational field. The results presented here differ from the
ones discussed by Rezzolla, Ahmedov and Miller (MNRAS, 322, 723 2001) mainly in
that we here consider the interior magnetic field to be dipolar with the same
radial dependence as the external one. While this assumption might not be a
realistic one, it should be seen as the application of our formalism to a case
often discussed in the literature.
