High-Precision Timing of Millisecond Pulsars and Precision Astrometry

Abstract

We present the technique of long-term, high-precision timing of millisecond pulsars as applied to precision astrometry. We provide a tutorial on pulsars and pulsar timing, as well as up-to-date results of long-term observation of two millisecond pulsars. We consider the feasibility of tying the extragalactic and optical reference frames to that defined by solar system objects, and we conclude that precision astrometry from millisecond pulsar timing will continue to yield interesting results at an accelerating pace in the next decade.
