Abstract
General relativistic effects, due to spacetime curvature and rotation, on the arrival times of pulsar signals are investigated using a rotationally perturbed spherical metric. For the millisecond pulsar PSR 1937 + 214, the advancement in arrival time (assuming the usual polar cap model for emission mechanism and a radius-to-frequency mapping) due to these effects is found to be nontrivial. The results are compared with recent multifrequency timing measurements on PSR 1937 + 214, and the implications regarding emission region thickness and emission mechanism for fast pulsars are discussed. 19 references.
