Chandra measurements of the proper motion of the γ-ray pulsar J0633+0632

Abstract

Abstract We measured the proper motion of a γ-ray radio-quiet pulsar J0633+0632 using Chandra observations performed in 2009 and 2017. The measured proper motion is 53 ± 15 mas yr−1. We found that the proper motion direction does not follow the extension of the J0633+0632 pulsar wind nebula. The J0633+0632 pulsar wind nebula therefore can be a jet-like feature or a misaligned outflow. We also discuss a possible birth cite of the pulsar.
