Scientific paper

Propagation of photons in the space-time exterior of a rapidly rotating neutron star is investigated, using a rotationally perturbed spherical metric, to determine the pulse profile of fast pulsars. It is found that space-time curvature produces a substantial amount of divergence in the pulse beam width accompanied by a reduction in the pulse intensity. Effects due to rotation are comparatively smaller, but rotation has the qualitatively important feature of producing a tilt of the pulse cone in the direction of rotation and a deformation of the cone. The asymmetry in the resultant pulse profile introduces a time delay in the arrival of photons emitted within the cone, which in turn affects the duty cycle of the pulsar.
