Pulsar braking and the P–$\dot{P}$ diagram

Abstract:

The location of radio pulsars in the period–period derivative (P–P˙) plane has been a key diagnostic tool since the early days of pulsar astronomy. Of particular importance is how pulsars evolve through the P–P˙ diagram with time. Here we show that the decay of the inclination angle (α˙) between the magnetic and rotation axes plays a critical role. In particular, α˙ strongly impacts on the braking torque, an effect that has been largely ignored in previous work. We carry out simulations that ...
