摘要：According to the ‘beads on a wire’ approximation, electrons that flow out of pulsarmagnetosphere are dragged into corotational motion by strong magnetic field. We develop a simple analytical model to learn how this phenomenon affects pulse shapes and polarisation. The caustic peaks and fast changes of polarisation angle are found to be intimately related to the regions in pulsar magnetospherewhere the curvature of electron trajectories in the inertial observer frame vanishes, or is minimal.
