Description

We have detected relativistic and/or kinematic post-Keplerian parameters of no fewer than five pulsar-white dwarf binary systems in long-term timing observations at Arecibo. We discuss the resulting constraints on pulsar and companion masses. The general trend is that the pulsar mass measurements are compatible with the canonical value of 1.35 solar masses, but in most cases somewhat higher masses are preferred.
