Statistics of interpulse radio pulsars: the key to solving the alignment/counter-alignment problem.


Abstract (from CDS):

At present, there are theoretical models of radio pulsar evolution that predict both the alignment, i.e. evolution of inclination angle χ between magnetic and rotational axes to 0°, and its counter-alignment, i.e. evolution to 90°. At the same time, both models describe well the pulsar distribution on the P-{dot}P diagram. For this reason, up to now it was impossible to determine the braking mechanisms since it was rather difficult to estimate the evolution of the inclination angle based on observations. In this paper, we demonstrate that the statistics of interpulse pulsars can give us the key to solve the alignment/counter-alignment problem as the number of interpulse pulsars (having both χ ∼ 0° and χ ∼ 90°) drastically depends on the evolution of the inclination angle.
