Talk	Oral abstract	Title	The wrapping of magnetic field lines due to frame dragging around a neutron star
Co-authors	Rhameez Herbst and Ebrahim Momoniat
Abstract	About 30 years ago Remo Ruffini asked me if radiation from a neutron star would be enhanced or reduced by relativistic effects. On the one hand lines of force “hitting the light cylinder” seem to enhance it; on the other, the lines of force may be “wrapped around the star” due to frame dragging. My first intuition was the latter but first attempts by Belinski et al and by De Paolis and me, seemed to support the former. Here an obliquely rotating magnetic dipole was boosted (in the latter case embedded in a neutron star) for constant circular motion. A better attempt using the work of Haxton and Ruffini lent itself to incorporating the effect of mass. A crude attempt by Al-Aithan et al seemed to support the earlier intuition, but its reliability was dubious. We now definitely find that the lines of force do get wrapped around the star and the radiation is suppressed.
