Proposal Type: General Category: Observation Category: Total Time Requested: Prop osal Title: ABSTRACT: Long-term Pulsars Galactic 10 Hours

One more orbit: long-term timing of PSR J0407+1607

We request 10 hr of Arecib o time spread over the next 2 years to extend our existing database of time-of-arrival measurements for the 1.8-yr binary pulsar J0407+1607. The goal of these observations is to measure the prop er motion and rate of change of the pro jected semi-ma jor axis. From this we should b e able to constrain the orbital inclination of the binary system with resp ect to the plane of the sky and the masses of the pulsar and its companion. In addition to providing invaluable input for future constraints of the strong equivalence principle, the prop er motion data would b e useful for studies of the origin and evolution of low-mass binary pulsars.
