On the Nature of Radio Pulsars with Long Periods

Abstract

We show that the drift waves near the light cylinder can cause modulation of the emission with periods of the order of several seconds. These periods explain the intervals between successive pulses observed in magnetars and radio pulsars with long periods. The model under consideration makes it possible to calculate the real rotation periods of the host neutron stars. They are less than 1 s for the investigated objects. The magnetic fields at the surface of the neutron star are of the order of 1011-1013 G and equal to the usual fields for known radio pulsars.
