Timing Measurements of the Relativistic Binary Pulsar PSR B1913+16

Understand

We present results of more than three decades of timing measurements of the first known binary pulsar, PSR B1913+16.

• Like most other pulsars, its rotational behavior over such long time scales is significantly affected by small-scale irregularities not explicitly accounted for in a deterministic model.
• Nevertheless, the physically important astrometric, spin, and orbital parameters are well determined and well decoupled from the timing noise.
• We have determined a significant result for proper motion, $\mu_{\alpha} = -1.43\pm0.13$, $\mu_{\delta}=-0.70\pm0.13$ mas yr$^{-1}$.
