Among a sample of 140 OB associations and clusters, we want to identify probable parent associations for the Guitar pulsar (PSR B2224+65), which would then also constrain its age. For this purpose, we are using an Euler–Cauchy technique, treating the vertical component of the Galactic potential to calculate the trajectories of the pulsar and each association into the past. To include errors, we use Monte Carlo simulations varying the initial parameters within their error intervals. The whole range of possible pulsar radial velocities is taken into account during the simulations.
We find that the Guitar pulsar most probably originated from the Cygnus OB3 association ≈0.8 Myr ago, inferring a current radial velocity of vr≈−30 km s−1, consistent with the inclination of its bow shock.
