Abstract: (ADS)
The motion of a rigid axisymmetric deformed pulsar model in which the body symmetry axis is inclined to the angular momentum axis will modulate the emission from a pulsar introducing such features into individual pulse structure as quasi-periodic drifting, nulling, and mode switching, much as is seen in certain pulsars. For very small eccentricity, the period of the modulation can be very long (many orders of magnitude) compared to the pulsar period. In certain situations the modulation due to precession can simulate orbital motion of a pulsar with a companion. It can also produce long null intervals, or otherwise modulate both the intensity and the frequency of the pulsar signals.References(0)
