Abstract

We report on 5 yr of pulsar observations of the globular cluster NGC 5904 (M5). A timing model has been obtained for the two known pulsars, and a deep search for additional faint isolated pulsars has lowered the detection flux limit to 40 μJy without further detection. We discuss the details and implications of the phase coherent timing models for PSR B1516+02A and PSR B1516+02B. Of particular interest for the binary PSR B1516+02B are the observed negative period derivative due to acceleration in the gravitational field of M5 and a detection of orbital precession.
