Revised Proper-Motion Results for the Soft X-Ray--emitting Radio Pulsar PSR 0656+14
Abstract
A third set of astrometric observations of the soft X-ray-emitting radio pulsar PSR 0656+14 has been carried out with the NRAO Very Large Array. Our result for the magnitude of the proper motion, 0.070 sec +/- 0.010 sec yr-1, is in agreement with our previously reported result based on the first two observations. The direction of motion, however, has been found to be 180 deg from that previously reported. This casts doubt on a proposed connection between this pulsar and the Gemini-Monoceros X-Ray Enhancement.
