Timing Fast Pulsars at the GBT

Abstract

Continuing a successful program begun at the VLA in 1990, we propose to make timing observations of four recycled pulsars. Our major goals include characterization of the planetary mass companion in the triple pulsar system B1620-26, and estimates of component masses in the B1802-07 and B1820-11 binaries, as well as inter-observatory calibration using the fast isolated pulsar B1937+21. This program can be easily and flexibly scheduled, and offers significant scientific return and a straightforward commissioning-phase test of the pulsar timing capabilities of the GBT.
